Warm-up•List homework in your agenda and turn in any late work see bin on window side counter.Predict: What is Matter?What are some of the components in the following items: loaf of bread, textbook, bicycle. *Can you break down any of the components even further? For example, one of the components of a book is obviously paper, but what are the components of paper? Record your thoughts in your science notebook/binder.
Warm-upCopy homework in agenda and pick it up from the table under the board.
If not finished recoding information for the marble volume quick lab finish now (you may get the marbles and graduated cylinders if needed).
Explain in your own words: What is volume? Draw a picture demonstrating you know what volume is using the correct metric units.
The Properties of Matter
Essential Questions: What is Matter?What is mass?
What is volume?
ObjectivesDescribe the two properties of all matter.
Identify the units used to measure volume and mass.
Distinguish between mass and weight.
Quick Lab (1) Material Getter
beaker Cup Paper towel
(2) Discussion Leader BEFORE EXPERIMENT: What do you expect the paper towel
to be like when it comes out of the bowl? AFTER EXPERIMENT: Was the paper towel like how you
expected? Draw conclusions as to why the paper is the way it is? How can you support this idea with science.
(3) Lab Initiator Wedge the paper towel in the bottom of the cup. All of the
paper towel should be mashed in the bottom of the cup, with no edges sticking out.
Place the cup upside down, perpendicular to the surface of the water.
Do not tilt the cup or place it at an angle. Push the cup into the water until the rim of the cup touches
the bottom of the bowl. Whole group: Countdown from 8. (4) Data Collector
Describe the paper towel before and after the experiment.
Matter
Matter is anything that has mass and takes up space.
It’s that simple! Everything in the universe that you can see is made up of some type of matter.
What do all these things have in
common?
They are all made-up of MATTER!
What ismatter?
Anything that has mass and takes up space
Everything you see: boats, cars, people
Some things you cannot see like air
Matter and Volume: The amount of space taken up, or occupied, by
an object is known as the objects volume.Liquid Volume Liters (L) and milliliters (mL)
are the units used most often to express the volume of liquids.
Measuring the Volume of Liquids -We will use a graduated cylinder instead of a measuring cup to measure the
volume of liquids. The curve at the surface of liquid is called a meniscus.
The space taken up by an object.
Two objects cannot share the same space.Ex: Air and Water in the quick lab
What isVolume?
Quick Lab ReviewCan water and air both occupy the inside
of a cup at the same time?As a lab group, review the results from
your experiment.Continue your discussion on why the
towel was the way it was AFTER your experiment. Can you now use science to support why the towel was dry?
Teacher shows what happens if there is a place for matter to escape.
What materialsare used to measure volume?
Graduated cylinders and beakers. Liquid in these have a meniscus curved water line
Read the bottom of the curve for accuracy
Define and Draw the meaning of: MeniscusDefine:
Meniscus is the curve at the surface of liquid.
Draw:
Meniscus
What unit is
Used to Measureliquidvolume?
Liters (l) and milliliters (ml)
Volume of a Regularly Shaped Solid Object The volume of any solid object is expressed in cubic units. The word cubic means having three dimensions.
Volume of an Irregularly Shaped Solid Object You can measure the volume of any solid object by measuring the volume of water that the object displaces.
How is the Volumeof a RegularlyShaped object
found?
Multiply the three dimensions of the object
volume = length x width x height or v = l x w x h
units used will be cubic meters (m3) or cubic centimeters (cm3)
How is thevolume of anIrregularlyshaped objectfound?
Water displacementmethod drop an object
in aknown volume of water (30 ml) the water level
will rise(40 ml) The differencebetween the 2 levelsrepresents the volume
ofthe object: 40 – 30 =
10ml1 ml = 1 cm3 both can
represent volumeAlmost always liquids
in ml and solids in cm3
Quick LabIn your Science binder, start a new page titled:Quick Lab. Finding the Volume of an Irregular Object.
Using what you have learned today, set-up a quick lab that allows you to measure the volume of the marbles at your table.
WHAT WERE YOUR RESULTS?
Mass and WeightMass:
Mass is the amount of matter in an object.
Weight:Weight is a measure of the gravitational
force exerted on an object.
Measuring Mass and WeightMass Measurement:
The SI unit of mass is the gram (g), but mass is often expressed in kilograms(kg) and milligrams (mg), too.
Weight Measurement: Weight is a measure of gravitational force and is expressed in the SI unit of force, the newton (N).
What is the differencebetweenmass and weight? video
Mass will stay the same for an object at any location
Mass measures an objects amount of matter
Measured in grams (g) or kilograms (kg)
Weight changes due to gravity’s force and distance of celestial body Planets, stars, etc.
Measured in Newtons and pounds
Review ObjectivesDescribe the three properties of all matter.
All matter has mass, volume Identify the units used to measure volume
and mass.The unit for Volume = milliliter (ml) or
cubic centimeter (cm3)The unit for Mass = kilogram (kg), gram (g),
and milligram (mg)
Distinguish between mass and weight.Mass is the amount of matter in an object.Weight is the gravitational force on an object.
Annotated reading assignment w/questions
Students work in partners, one reads while the other annotates:
Circle or underline words you do not understand.
Write any questions in the marginsAfter reading one paragraph students stop,
discuss and summarize, especially if there are words or phrases circled/questions in margins
For each paragraph switch jobs. After all of reading and discussion is complete begin questions. Take turns recording answers in space provided. Highlight the answer in the text and notate on the answer paragraph # and sentence # where found.
