O f f i c e o f E l e m e n t a r y E d u c a t i o n P a g e | 4Students will demonstrate the thinking and acting inherent in the practice of science.A. CONSTRUCTING KNOWLEDGE

1. Gather and question data from many different forms of scientific investigations which include reviewing appropriate print resources, observing what things are like or what is happening somewhere, collecting specimens for analysis, and doing experiments.

a. Support investigative findings with data found in books, articles, and databases, and identify the sources used and expect others to do the same.

b. Select and use appropriate tools hand lens or microscope (magnifiers), centimeter ruler (length), spring scale (weight), balance (mass), Celsius thermometer (temperature), graduated cylinder (liquid volume), and stopwatch (elapsed time) to augment observations of objects, events, and processes.

c. Explain that comparisons of data might not be fair because some conditions are not kept the same.

d. Recognize that the results of scientific investigations are seldom exactly the same, and when the differences are large, it is important to try to figure out why.

e. Follow directions carefully and keep accurate records of one's work in order to compare data gathered.

f. Identify possible reasons for differences in results from investigations including unexpected differences in the methods used or in the circumstances in which the investigation is carried out, and sometimes just because of uncertainties in observations.

g. Judge whether measurements and computations of quantities are reasonable in a familiar context by comparing them to typical values when measured to the nearest:

Millimeter - length Square centimeter - area Milliliter - volume Newton - weight Gram - mass Second - time Degree C - temperature

Standard 1.0 Skills and Processes

Students will demonstrate the thinking and acting inherent in the practice of science.

B. APPLYING EVIDENCE AND REASONING

1. Seek better reasons for believing something than "Everybody knows that..." or "I just know" and discount such reasons when given by others.

a. Develop explanations using knowledge possessed and evidence from observations, reliable print resources, and investigations.

b. Offer reasons for their findings and consider reasons suggested by others.

c. Review different explanations for the same set of observations and make more observations to resolve the differences.

d. Keep a notebook that describes observations made, carefully distinguishes actual observations from ideas and speculations about what was observed, and is understandable weeks or months later.C. COMMUNICATING SCIENTIFIC INFORMATION

1. Recognize that clear communication is an essential part of doing science because it enables scientists to inform others about their work, expose their ideas to criticism by other scientists, and stay informed about scientific discoveries around the world.

a. Make use of and analyze models, such as tables and graphs to summarize and interpret data.

b. Avoid choosing and reporting only the data that show what is expected by the person doing the choosing.

c. Submit work to the critique of others which involves discussing findings, posing questions, and challenging statements to clarify ideas.

d. Construct and share reasonable explanations for questions asked.

e. Recognize that doing science involves many different kinds of work and engages men and women of all ages and backgrounds.

1. DESIGN CONSTRAINTS: Develop designs and analyze the products: "Does it work?" "Could I make it work better?" "Could I have used better materials?"

a. Choose appropriate common materials for making simple mechanical constructions and repairing things.

b. Realize that there is no perfect design and that usually some features have to be sacrificed to get others, for example, designs that are best in one respect (safety or ease of use) may be inferior in other ways (cost or appearance).

c. Identify factors that must be considered in any technological design-cost, safety, environmental impact, and what will happen if the solution fails.2. DESIGNED SYSTEMS: Investigate a variety of mechanical systems and analyze the relationship among the parts.

a. Realize that in something that consists of many parts, the parts usually influence one another.

b. Explain that something may not work as well (or at all) if a part of it is missing, broken, worn out, mismatched, or misconnected.3. MAKING MODELS: Examine and modify models and discuss their limitations.

a. Explain that a model is a simplified imitation of something and that a model's value lies in suggesting how the thing modeled works.

b. Investigate and describe that seeing how a model works after changes are made to it may suggest how the real thing would work if the same were done to it.

c. Explain that models, such as geometric figures, number sequences, graphs, diagrams, sketches, number lines, maps, and stories can be used to represent objects, events, and processes in the real world, although such representations can never be exact in every detail.

d. Realize that one way to make sense of something is to think how it is like something more familiar.Standard 1.0 Skills and Processes

solventsolutesaturated solution

Focus Question

Is there a limit to the amount of salt that can dissolve in 50 ml of water?

A solution is made of two parts, the solvent and the solute. When a solute dissolves in a solvent until no more will dissolve, the result is a saturated solution. Salt will dissolve in water until it reaches saturation. No more salt will dissolve once saturation is reached. The amount of salt in a saturated solution can be determined by weighing the saturated solution and subtracting the mass of the water.

Focus Questions

What happens when a solution is made with water and two different solutes?

How do you know when a chemical reaction has occurred?

When two or more materials (chemicals) are mixed together and a change occurs, a chemical reaction has taken place. A precipitate is a solid material that forms as a product of a reaction. Change is the process of becoming something different. Sometimes when two or more chemicals are mix, changes take place and a new material form. Changes, such as heat, gas formation, and precipitate formation, are evidence of a chemical reaction.

Disappearing Water ~ Have the students write their names on clear plastic cups with a permanent marker. Fill the cups half full. Mark the water level on the cup with a permanent marker. Record the data for the next 3-5 days. Mark each water level on the cup and record the changes. Did the water change? Where do you think the water went? Can you think of other places water could be evaporated? (rivers, oceans, pebbles, fishbowls, swimming pools)

Resource: Science Experiments for Young Learners, Even Moor Corp

Water in the Air ~ Put several ice cubes in a jar. Put the lid on the jar and wipe off the outside of the jar with a paper towel. Let the jar sit in a warm place for a little while. Look at the jar to see what has happened. Record observations. What did you find on the outside of your jar? Where did the water come from? When the warm air touches the cold jar, the water in the air forms into drops they can see (condensation). Can you think of another place where you have seen water that came from air? (windshield, pitcher of lemonade, dew on the grass.)

Observing changes of state: water (gas – liquid) ~ Place a saucer of water inside a large glass jar or aquarium. Put some Vaseline around the rim of the container, and cover it with plastic wrap. Be sure it is tightly sealed. Students can observe the saucer periodically to see what happens to the water. (It will evaporate.) Ask where the water went. (It can be seen as droplets on the glass sides of the container.) Students will begin to understand that when water disappears (condenses), it usually becomes a liquid again. Students can repeat this activity using other liquids such as oil or solids such as cubes of ice.

Resource: Everyday Science Sourcebook, Lowery

Observing Condensation ~ Have students watch water condense on the outside of a jar with a seal after adding ice to it. Ask where the water comes from. If students think that the droplets come from the ice water through the glass, prepare an identical jar, but fill it with warm water. They will see that droplets do not form on this jar. They will realize that there is water in the air in the form of an invisible gas and the when the gas cools, as it goes against the glass, it takes on the form of a liquid. You can explain that the term condensation describe what they saw. Some students might tell about dew that they have seen and recall the time of day and conditions when it was observed (usually on cool mornings). Others can describe the droplets that form on windows, mirrors in bathrooms, and eyeglasses. Challenge them to recall the conditions that might have caused the droplets. The surface upon which the droplets formed was probably cool. Students will begin to realize that water in a gaseous state will condense as a liquid against cooler surfaces.

Resource: Everyday Science Sourcebook, Lowery

Observing evaporation ~ Students can take turns dripping a finger or hand in water and waving it until it dries. Let them describe what they feel, and ask them where the water went. Explain that when liquids, like water, seem to disappear, they have charged into an invisible gas. You might tell them that the term evaporation describes what they observe. Next, set a saucer of water in direct sunlight and have students check it periodically as the water evaporates.

Water Cycle Bottle

How is water constantly recycled on Earth?

Materials: Clear 2 liter soda bottle for each group (cut the top of the bottles about 20 centimeters from the bottom above the label. You’ll have a cylinder and a funnel. Make sure the caps are screwed on tightly. Remove the labels), 1 cup of warm water, cellophane tape, 3 ice cubes per group, and a sunny window

Pour the cup of warm water into the soda bottle cylinder. Screw the top tightly onto the funnel top of the soda bottle and place it upside down into the soda bottle cylinder. Use cellophane tape to seal the space where the two parts of the bottle join together. Place the bottle in direct sunlight for 5 minutes. What do you think will happen to the air temperature inside the bottle after it is exposed to the sun? Why? Observe the inner surface of the cylinder and the bottom of the funnel. Describe what you see. Place 2 or 3 ice cubes into the funnel and wait 5 minutes. What do you think will happen to the air temperature near the top of the soda bottle cylinder? Why?

Water Cycle Observations

What happens to water when it is left in a warm, closed system such as inside a Ziploc bag?

Materials: graduated cylinder, small plastic cups, large Ziploc bags, tape

Use the graduated cylinder to measure 40 mL of water into a small cup. Place the cup in the corner of the bag. Tape the cup to the back to hold it in place. Zip the bag shut and tape it to a window where it will get sunlight and heat. Predict what will happen to the water inside the cup over time. Observe the bag each day for 4 days and record the observations. At the end of day 4 write a summary of what happened to the water in the cup. Estimate or measure how much water is in the Ziploc bag. Record the measurements and compare it to the amount of water you put in the bag. Relate the process observed in the closed system to the water cycle in nature. Describe the evidence for each process ~ condensation, evaporation, and precipitation. Draw and label the water cycle as it occurred in the bag.

Extension: Follow the directions above adding 5 mL of salt to the 40 mL of water in the cup.

Session One

1. Tell students that they are going to build a model of the water cycle. Have students describe the meaning of model in their own words. (A model is a representation of something else.)

2. Distribute a copy of the Water Cycle Model Science Notebook Sheets (pages 1-3) to each student.

3. Explain to students how to set up the model. In a cup, place one rock that has been warmed. Using a graduated cylinder or beaker, pour 75 ml of warm water into the cup. Cover the cup with a second cup, placed upside down. You may want to place a few pieces of tape to keep the two cups attached. Place a third cup right side up on top of the first two cups. Fill the top cup with ice.

4. Have one student from each group come up and get 3 cups, a rock, and some tape pieces. Tell students to begin to set up their water cycle models. One student from each group should also collect a cup of ice, and one student should measure 75 ml of water and pour it into the cup with the rock.

The rock represents Earth’s land. Direct students to write a prediction on page 1 of the Water Cycle Model Science Notebook Sheet about what they think will happen in the water cycle model. Remind students to explain their thinking in the “I think this because…” section of the sheet.

6. Have students turn to page 2 of the Water Cycle Model Science Notebook Sheets. Ask them to draw a picture of their water cycle model in the box on the left side of that page (under “Water Cycle Model – start”).

7. Have students place their models next to a window for one hour.

Session 2, one hour after Session 1

8. Have students observe their water cycle models. Have students answer questions 3a and 3b on page 3 of the Water Cycle Model Science Notebook Sheet to guide their observations. Students should look for changes in the model.

9. Have students turn back to page 2 of the Water Cycle Model Science Notebook Sheets. Ask them to draw a picture of what their water cycle model looks like now in the box on the right side of that page (under “Water Cycle Model – 1 hour later”). When they have completed their drawings, take time to have students compare and contrast the “start” and “1 hour later” drawings as a class.

10. Write evaporation on the board. Review with students that evaporation is when water changes from a liquid to a gas, like when a puddle dries up. Ask students if they think evaporation happened in their model. (Some students should say yes.) Ask the students if they saw, or observed, evaporation happening. (No, students could not actually observe evaporation happening.) Ask students what made them think evaporation might have happened. (They may have observed that the water level in the bottom cup was lower.). Tell students that they inferred that evaporation occurred. They did not observe evaporation, but they found evidence to suggest that evaporation occurred. The lower water level and identification of water in places where it wasn’t before provides evidence for evaporation. Have students record their thinking in question 4a on page 3 of the science notebook sheets.

11. Write condensation on the board. Review with students that condensation is when water changes from a gas (such as water vapor) to a liquid, like the example of dew on grass that they read about. Ask students if they think condensation happened in their model. (Answers will vary.) Ask if any students observed WCPS 2010 Grade 5 Standard 4: Chemistry

Page 48: Science Grade 5 Unit 2 Guide 2010

O f f i c e o f E l e m e n t a r y E d u c a t i o n P a g e | 48condensation occurring. (No, students could not actually observe condensation occurring.) Ask students what made them think condensation might have happened. (They may have observed that the water droplets formed at the top of the cup.) Tell students that they inferred that condensation occurred. They did not observe condensation, but they found evidence to suggest that condensation occurred. Water droplets formed in another location in the model, near the cold ice. When you infer, you make a statement that something happened based on evidence, but not direct observation. Have students record their thinking in question 4b on page 3 of the science notebook sheets.

Note Students may also observe that the outside of the plastic cup of ice is “wet.” Ask students how they think the water got there. (Accept all responses.) Remind students that water vapor is part of the air all around us. Water vapor is part of the air all around the water cycle model, too. Ask students if they know what happens to water vapor when it is cooled. (Accept all responses.) Point out that the ice has made the outside of the top cup colder. The cold cup cools the air around it. Water vapor in the air turns into droplets of water on the outside of the cup. This is not really part of the model of the water cycle they have created, but it certainly is another example of condensation.

12. Write precipitation on the board. Tell students that precipitation is any form of water falling from clouds to Earth. Rain, snow, sleet, and hail are forms of precipitation. Ask students if they think they observed precipitation in the model. If students see drops of water fall from the top of one cup to the other, then they are observing precipitation. Have students record their thinking in question 4b on page 3 of the science notebook sheets.

13. Have students use the markers to draw arrows on the cups to show the water cycle process. Use a different color marker to make the arrow for each of the three stages: evaporation, condensation, and precipitation. Have students place self-adhesive labels that say evaporation, condensation, and precipitation on the model.

14. Have students begin to think about the sequence, or steps of the water cycle. Ask students what causes the water cycle. Students may suggest evaporation. If so, ask them what causes evaporation. If students suggest condensation, ask where the water comes from for condensation to occur. Take students through the water cycle process to the sun. Energy causes motion. The water is put into motion because of the energy from the sun. The sun drives the water cycle. The energy from the sun causes evaporation. The water vapor rises into the cool air in the atmosphere. The vapor cools and forms droplets of water. This is called condensation. When the droplets get too big and heavy, they fall to the ground as precipitation. The water accumulates in streams, rivers, ponds, oceans, and puddles. The water is also absorbed by the soil for plants and rocks. The sun can then cause the cycle to start all over again.

15. Review the vocabulary words and post word cards on the word wall.

Teacher Script for

Water Cycle Bracelet

Materials:

Pony beads ~ 1 of each color (see below) per student

String ~ approximately one 6” piece per student

Directions:

Below are suggested bead colors for each description of the water cycle. However, it is best to just read the description and allow the students to pick the bead color. This way gives them ownership so they will remember what their beads represent when they describe the water cycle. For example some students may want to use the dark blue bead for precipitation and the light blue bead for oceans, lakes, ponds, and stream based on their interpretation.

Light blue bead ~ This bead represents precipitation (rain or snow that falls to the ground).

Dark blue bead ~ This bead represents oceans, lakes, ponds and streams where some of the rainfall flows. When water falls to the ground some of it runs off directly into streams and rivers and some of it soaks into the soil to become ground water.

Green bead ~ This bead represents the plants and trees that use the water. Transpiration is the process through which excess water is released from plants through tiny openings called stomata, as water vapor.

Yellow bead ~ The Sun provides energy needed for water to change from a liquid to a gaseous state so that transpiration and evaporation can occur.

Clear/silver bead ~ Evaporation takes place from open surface areas of water. When water is heated by the sun it changes from a liquid to a gas, water vapor, and rises into the air. Water evaporates faster the higher the temperature and the larger the surface area of the water body.

White bead ~ This bead represents the way water vapor forms clouds. Water vapor condenses or comes together into tiny droplets that attach to specks of dirt or dust that then forms clouds.

Tie the bracelet into a knot. The water cycle is continuously reoccurring. The water on earth today is the same water that existed billions of years ago.

Water Cycle

Background information

Energy from the Sun drives the water cycle. The Sun’s heat warms the water on Earth’s surface. It makes water from oceans, lakes, rivers, and plants evaporate. During evaporation, liquid water becomes water vapor, a gas in the air. The water vapor rises high into the atmosphere. There, the water vapor cools and condenses. It forms tiny water droplets. The water droplets form clouds. The water droplets in clouds become larger and heavier. They fall to Earth as precipitation. Precipitation can be rain, snow, sleet, or hail. The temperature determines the type of precipitation that reaches Earth.

When precipitation hits Earth, most flows downhill into streams, rivers, and the oceans. This water is called runoff. Some precipitation soaks into the ground. This is called groundwater. Some runoff and groundwater become our water supply. Some precipitation is absorbed by plants.

The Sun’s energy keeps warming the water in streams, rivers, and the oceans. The water evaporates. The cycle continues.

Measuring Liquid Volumes ~ The volumes of a liquid can be measured in a number of ways by using any small container to fill a larger one. Each filling from the small container represents a unit of measure.

a. Arrange containers of various sizes and shapes for students to see. Fill a drinking glass to the brim with water or another liquid (the liquid should be colored so that it can be easily observed). Ask students to estimate how high the liquid would be if it were pointed into one of the other containers. Empty the contents into one container, refill the glass, and repeat for several containers. Discuss the various levels observed. Note: Liquids take on the shape of the

container that holds them. This fact often misleads children, because a tall, narrow, container seems to contain more liquid than a shallow, wider one.) Ask how the different levels might be measured. The amounts have already been measured; the same tumbler was used to each case.

b. Fill a large container to see how many tumblers or other units of measurement it will hold.c. Partially fill a large bucket with water or other liquid. Ask students to determine how much water is in the bucket. They can use tumblers or other containers

to find out the volume of the water (the water can be withdrawn in equal units.) Possible measuring containers range from thimbles to buckets. Students can choose the best size unit to use.

Resource: Everyday Science Sourcebook, Lowery

Weighing liquids ~ To help students realize that any weighing is a comparison of a known amount (mass) whose weight has been decided against an unknown amount (mass), ask them to determine the actual weight of an amount of water (mass) in a carton that is filled to the brim. They can use arbitrary units of measure (e.g., washers, nails, pennies, marbles) or standard units. Compare results with the weights of other liquids in identical cartons.

Observe and describe the changes heating and cooling causes to the different states in which water exists.

Heating causes: ice (solid) to melt forming liquid water; liquid water to evaporate forming water vapor (gas).

Cooling causes: liquid water to freeze forming ice (solid); water vapor (gas) to form liquid water.

MSDE Clarification

Heating and cooling cause changes in the properties of materials. When liquid water disappears, it turns into a gas (vapor) in the air and can reappear as a liquid when cooled, or a solid if cooled below the freezing point of water. Water turns from a solid to a liquid when it absorbs enough heat. If it absorbs even more heat, the water will turn to a gas (steam or vapor). Melting and boiling points are the temperatures at which matter changes state.

Observing Changes of State

Ice (solid ~ liquid) ~ Have the students watch ice cubes melt in dishes placed in different parts of the classroom. After seeing which melts fastest, let them try to tell why. (It is usually because of heat.) Challenge the students to bring a solid ice cube to school from home. (They will have to be inventive to keep it from melting.) Discuss factors that contributed to those that were brought successfully to school. Next, challenge students to devise ways to make ice cubes spherical, hollow, or various other shapes. They might discover that the shape (i.e., amount of surface area) influences the rate at which each melts. For controlled comparisons, differently shaped ice of equal volumes can be made by pouring equal amounts of water into paper cups with flat bottoms and pointed bottoms; various candy cups; cookie molds; round lids or covers; tall cylinders. Set the frozen shapes of dishes in the same locations to keep temperature conditions the same. Students can record and compare the time it takes each to melt.

Determining the melting point of different solids ~ Students can harden some olive oil in a jar by placing it in a refrigerator for a day. When hard, set the jar of oil in a sunny place. As the oil stars to melt, tip the jar so that the students can take the oil’s temperature. Have them record the melting point, then follow the same procedure using margarine, butter, lard, ice, and ice cream. The different materials can be seriated by their melting points.

Observing Condensation (liquid ~ gas) ~ Fill a quart or liter jar with ice water, let it stand out in the room, and have student observe the moisture that collects on the outside of the jar. Add some food coloring or ink to the water in the jar, and they will realize that because moisture on the outside is clear, it probably did not come through glass. Students can also exhale against the glass and watch the moisture form. Tell them what they observed is called condensation. You might make analogies to common experience such as the formation of moisture on mirrors and windows.

Based on data explain the importance of water’s ability to exist in all three states within the temperatures normally found on Earth.

MSDE Clarification

Classroom Example

Water exists in three states of matter on Earth. This iceberg--floating on liquid water in the Arctic Ocean--represents water in its solid state. The atmosphere surrounding the iceberg contains water in a gaseous form known as water vapor.

The water cycle helps to sustain life on Earth through the constant cycling of water between the atmosphere, the ocean, organisms and the land. Although water continuously changes states from solid to liquid to gas, the amount of water on Earth stays the same. There is as much water now as there was hundreds of millions of years ago. The properties of water in the liquid state are most important to life on Earth. Water’s ability to dissolve nutrients and gases is critical to sustaining life in terrestrial and aquatic environments. Sea water and fresh water provide habitats for many organisms. Water in the gaseous state in the atmosphere is transported to most parts of the Earth. As it condenses and falls to Earth as precipitation, it helps provide a suitable habitat for terrestrial organisms.

WHICH STATE IS MOST IMPORTANT?Ask students to brainstorm examples of different states of water found on Earth. Give a reason or use for each example. Divide ideas into the three states of water: solid, liquid, and gas. Students use various reference materials to research their example and determine its importance on Earth. (Students may use a scale of 1-5, less important to most important.) Have each group present their research and defend their importance ratings.

Analyze data from observations to support the idea that when materials change from one state to another the amount of material stays the same.

MSDE Clarification

When materials change from one state to another, although the properties change, the mass stays the same. Also, when matter expands or contracts because of the gaining or losing of heat, the amount of matter does not change. The mass of a cup of water, before and after freezing, will remain the same. A plastic bottle that expands when held in warm water has the same amount of mass as the same bottle contracting when placed in a bowl of ice.

Classroom Example

Object Mass before Type of Change

Chocolate bar 9 grams Melted

Investigate and describe what happens to the properties of materials when several materials are combined to make a mixture, such as table salt and pepper; various kinds of nuts, chocolate pieces, and coconut; sugar dissolved in

milk.

MSDE Clarification

When materials are physically combined, they form a mixture. In mixtures, the parts blend together without forming a new substance. The materials in a mixture keep their original properties.

A solution is a mixture that is blended completely and can be separated into the original substances using one or more properties (color, shape, density, boiling point, solubility).

Saltwater is a mixture of salt dissolved in water. This is an example of a physical change since no new materials were formed in the process. This mixture could be separated by evaporating the water, leaving the salt behind.

Directions1. Give each group or pair of students a sample of the mixture, a magnet, filter paper, water, and a spoon. Tell them that one of the substances is salt. Have students

examine the mixture and determine how many substances are in the mixture. (4) 2. Have each group write a procedure explaining how they will separate the parts of the mixture. 3. Have each group follow their procedure to separate the mixture.

Sample procedure:

Use the magnet to remove the iron filings. Add water to make foam pieces float. Stir to dissolve salt. Sand will sink so salt water can be poured through filter to separate sand and salt water. Evaporate water to leave salt behind. Discuss as a class which methods were most successful.

Students should follow all local school system safety guidelines during investigations.

Observing Some Solids That Dissolve ~ After students examine the characteristics of solid pieces of salt and sugar with a hand lens, let them place 1 teaspoon of each in different jars of water. The materials will dissolve. Next, set the jars in the sunlight or near a heat source to allow the water to evaporate. When the water has evaporated, the students can examine the solid materials again with a hand lens. They will realize that water can contain unseen, dissolved solid materials. Encourage them to test other solid materials to see which dissolved and which do not.

Observing materials dissolving in water ~ Have students bring several tea bags to school. Cut a hole in the top of each bag and remove the tea. Pour dissolvable material into each tea bag (for example, salt, sugar, etc.) Place each bag in a separate beaker of warm water. Let students observe and describe what WCPS 2010-2011 Grade 5 Standard 4: Chemistry

they see. (Note: A sheet of black paper placed behind the beakers will aid the observations.) Test other materials in a similar way. Students will find that some dissolve and some do not.

Resource: Everyday Science Sourcebook, Lowery

Comparing the times at which different solutions freeze ~ Give students four or five plastic water bottles without the lids containing water in which different amounts of salt have dissolved (e.g. 0 teaspoons full, 1 teaspoons full, 2 teaspoons full, or use 5 ml spoon full.) Have them place the jars in plastic bags and set the bags in a freezer. Compare the times it takes for different solutions to freeze by checking them at half hour intervals. (Note: Some may never freeze.) Remove the jars after four hours and record the results. The jars can be left in the schoolroom to see which frozen solution melts first. Students will see whether or not a salt solution inhibits the melting of water. This activity can be repeated using different solutions such as sugar.

O f f i c e o f E l e m e n t a r y E d u c a t i o n P a g e 125

Time frame: About an hour

1. Show the students a breath mint or hard candy and pose the following question: What are some things you think might affect how quickly a piece of candy like this would dissolve? Have student in small groups brainstorm factors. Choose just one of those factors to experiment with. Try to find out whether or not it really does affect how quickly the candy dissolves in liquid.

2. Help the student procure any materials they will need for their experiments. For example, if students are testing with water temperature, they will need access to a range of hot and cold water, and possibly a thermometer. If they are comparing dissolving rates in different types of liquids, they might want to use water, vinegar, seltzer water, juice, etc. Other materials (salt or stirring sticks, for example) might also be requested. Most students will set up their experiments in their clear plastic cups provided, but even the containers could be considered a factor to be tested. If the materials requested by the students are not available, have them choose a different factor to test.

3. After the students have set up and run their experiments, have them describe their procedures and summarize their results.

Assessment Criteria

Whether the experiment they designed is a valid test of the factor they have selected How clearly they describe their experiment and communicate their results Whether the conclusion they draw are valid

Prompts for Getting Started

What will your experiment tell you? How can you make your experiment a fair test of the factor? What do you predict might happen in your experiment?

Assessing the Work

How well students can isolate and test one factor (variable)? Did the student conduct a well-organized and reliable experiment? Did the student’s experiment test one factor only, with controlling all others? Is the experiment clearly described? Are the experimental results or conclusions clearly stated and reasonable?

Scoring Rubric

Low Response The student has been unable to identify, isolate, and test a factor for its effect. The concept of dissolving may

have been explored informally, but a controlled experiment has not been conducted. The report may be fairly clear in detailing the student’s procedures.

Medium Response An experiment has been set up and conducted, although the experimental procedures may be flawed. The experiment is fairly clearly described. Because of problems in experimental procedures, conclusions are based on questionable evidence.

High Response The experiment is well organized and a valid test of the factor in question. Experimental procedures are clearly described, and a reasonable conclusion has been drawn.

Extending the Learning

Have the students make a list of the factors the students thought might influence the dissolving rate of a piece of candy in water. Pick one of the factors from the list. Have the students discuss how they think and experiment for that factor should be conducted.

Talking It Over

What is the best way to find out if the temperature of the water makes a difference? What are the steps we should go through?

What does everyone think? Is stirring alright?

Which liquid mixtures will separate?

Materials: for each group 3 cups labeled for vinegar, water, and cooking oil ~ add 5 mL of each liquid to the cups, goggles, marking pen for each group, stirring sticks, and post it notes

Label the three cups as vinegar and water, vinegar and oil, and water and oil. Predict which mixtures will separate after the liquids are combined. Add about half of each liquid to the appropriate cups, and mix with a stirring stick. After five minutes, observe each cup to see if the mixture separated. Record the results. Try other liquids such as honey, lemonade, or milk mixed with water or oil.

Formative Assessments

“Formative assessments are used to gain information that improves instruction and advances student learning. Formative assessment entails both “gathering information about children’s ongoing development of ideas and skills and using this in modifying activities and the teacher’s interventions to meet the children’s needs” (Harlen 2001, p. 64) This process of gathering and using information about student understanding is thus ongoing and cyclical.”

Resource: Science and Learning, March 2007, “Assessing for Science Learning”, Michele H. Lee and Sandra K. Abell

Administering the formative assessments is optional and the scores are NOT reported.

Formative assessments provide an opportunity to informally assess students after each investigation for instructional purposes.

The formative assessments do not serve as a “practice” for the end of the unit assessment.

A formative assessment is provided for each unit investigation.A key is provided for each formative assessment.

Literature in the Science Classroom

“The use of literature in the science classroom enhances student understanding of scientific concepts. Literature can expose students to lives of real and fictitious people were instrumental in scientific discovery or who have applied scientific ideas to real-life situations.” Resource: Fossweb.com

“Children should be encouraged to use many different books to learn about science. A book can be the expert to refer to for an answer or clarification, or a book can spark an interest or an investigation. More often, however, books, simply serve to deepen a child’s understanding of some familiar topic, helping them to make increasing sense of the world and function more confidently in it.”

Teacher DirectionsPART 1Distribute the Test Materials

Today we are going to take the Unit 2 Science test. Do your best to select or write an answer for each question on the test.I am now going to give you the test materials you will need. Please do not open your Test Book until I tell you to do so.

Distribute the Test Books, No. 2 pencils with erasers, and scratch paper.

The Unit 2 Science consists of Selected Response (SR) questions and Brief Constructed Response (BCR) questions. The SR questions require you to select the correct answer from four choices and darken the appropriate circle in the Test Book. BCR questions require you to write your response in the boxed answer area of the Test Book. Now turn to page 3 in your Test Book. Read the directions to yourself as I read them aloud.

Selected Response Instructions•Be sure to fill in the circle completely and make your mark heavy and dark in your test book and on your scan sheet.• If you want to change an answer, completely erase the mark you made before making a new mark.• Remember to read and follow all directions and information in the Test Book.

Brief Constructed Response Instructions • In addition to Selected Response questions, there will be Brief Constructed Response questions that require a written answer.

• You may underline, mark, and make calculations and notes in your Test Book; however, be sure to mark and write all your answers in the space provided in your Test Book.• Remember, only what you write in the boxed area in your Test Book will be scored.

For Constructed Response questions, you do not need to use the entire answer space. Do not write outside the boxed area. Answers written outside the boxed area will not be scored. To answer some of the questions on this test, you will be asked to read a passage or review a diagram. Questions will follow each passage or diagram. If you do not know the answer to a question, do your best but do not spend too much time on any one item. You may return later if time permits during that Test Part. Do you have any questions?

Answer any questions students may have. Repeat any of the instructions, as necessary.

explanation of the water cycle. the role of the sun.

2.E.1.a Score Student Response3 ~ Full and Complete Understanding

The response includes but not limited to: The sun is our main source of energy. It warms the water and the water begins to evaporate. The water vapor (gas) becomes part of the air and rises into the atmosphere. The higher the air gets the cooler it gets and the water vapor (gas) begins to condense. The

gas turns back into tiny droplets of water. This is called condensation. The droplets become large and heavy and fall back to Earth as precipitation (rain, sleet,

snow, etc.) Without evaporation condensation would not occur. Therefore, precipitation in the form of

raindrops also would not occur.2 ~ General Understanding

The response includes a general description of the water cycle and included the conclusion that without evaporation or condensation, precipitation would not occur.

1 ~ Minimal Understanding

The response includes a minimal description of the water cycle and does not conclude that without evaporation or condensation, precipitation would not occur.

This summer we experienced a drought. Local farmers reported that their crops were destroyed and their fields showed evidence of soil erosion.

29. Which natural agent would be responsible for soil erosion? In your explanation be sure to include why other natural agents would not be responsible for the soil erosion during a drought.

2.A.1.a Score Student Response3 ~ Full and Complete Understanding

The response includes but not limited to: The natural agent responsible for the soil erosion is wind. Wind has moved the soil from one place to another. Other natural agents such as water and ice would have not been responsible for the soil

erosion. A drought is a when there is very little or no rain for a period of time. The drought occurred in the summer, so the air would be too warm for ice.

2 ~ General Understanding

The response includes that wind is the natural agent responsible for soil erosion and the other agents that were not responsible but does not explain why.

1 ~ Minimal Understanding

The response includes that wind is the natural agent responsible for soil erosion but does not identify the other agents not responsible and/or does not clearly explain why.

0 ~ No Understanding Other
