How is science like a puzzle?

X-Box Conclusions1. Science is like a puzzle we have not yet solved – we

assume all the pieces fit together2. Trial and Error are essential in science3. Sometimes we get lucky and find the right answer4. Current information may be incomplete or incorrect5. New information may require old theory to be

changed6. Working together is helpful7. Once we get the answer it seems to all make sense8. Communicating our results to others benefits the

entire scientific community

These 8 things describe science

but…what is Science?

What is Science…

a way of knowing and understanding the natural world.

Can science study/answer/explain ALL things…

No! Science has limits.• Should animals have rights?• Did Beethoven or Mozart write better symphonies?• Just because we can create a new type of bacteria, should we?• Does God exist?

What isn’t Science…

Science Has Limits!

• Science doesn't make moral judgments• Science doesn't make aesthetic judgments• Science doesn't tell you how to use scientific

knowledge• Science doesn't draw conclusions about

supernatural explanations

What isn’t Science…

Science Looks for evidence and explanations!

Let’s Try• Dog fighting is wrong.• Nuclear weapons are effective.• Bottle water is cleaner than tap water.• The Razorbacks are more awesome than any

other team.• I think steel chairs are stronger than wood chairs. • Ghosts are scary.

What is Science, What isn’t Science…

We’ve described science, we’ve defined what science

is and isn’t, but how do we do Science?!

Science Process SkillsHow scientists think

• Observe – to use one or more of your senses to gather information.

• Infer – to explain or interpret the things you observe.

• Research – gathering information to inform predictions

• Predict – to make a forecast of what will happen in the future based on past experience or evidence.

• Hypothesis – an educated prediction

• Experiment – a process to test a hypothesis

• Collect/Analyze Data – looking at the facts, figures, or other evidence gathered through observations and experiments

• Draw Conclusions – summarizing what you have learned from an experiment (was the hypothesis supported?, do we need to do more?)

• Communicate Results – sharing the results of the experiment with others through writing and/or speaking

Science Process SkillsHow scientists think

• Classify – to group together items that are alike in some way

• Make Models – to create a representation of an object or process

•Are scientists the only ones that use these skills?

Graphs Notes• Double Line Graph – used to compare 2 sets of data – usually over time

Graphs Notes• Scatter Plot – used to plot data in order to see trends or patterns

Graphs Notes• Histogram – similar to a bar graph but uses data ranges on the X-

axis and the bars are touching
