The Nature of Science

Which of the following descriptions accurately describes the nature of science?

CHECK ALL THAT APPLY

• constant (never changing)

• based on evidence

• tentative (always changing)

• based on beliefs

• historical

The variable that is being measured or observed is called the _______________. Hint: this is the variable that is the result or effect

• independent variable

• dependent variable

• control variable

Why do we want to test one variable at a time?

• Because it is hard to setup a data table with more
• To know what is causing the changes. This helps us understand cause and effect.
• It is what has always been done

What is being changed in this experiment?

• ramp height
• the speed that the ball rolls
