THE GOAL OF SCIENCE IS…
To investigate To understand To explain

HOW DO SCIENTISTS DO SCIENCE?
Using a method called
Scientific Inquiry
![Page 8: Scientific inquiry powerpoint](https://reader035.vdocuments.net/reader035/viewer/2022062418/556ba5ccd8b42a207e8b4a32/html5/thumbnails/8.jpg)
STEPS TO SCIENTIFIC INQUIRY
State the problem by posing a question.
Make observations. Form hypothesis. Design an experiment. Collect, record, and analyze
data. Draw conclusions.

1. POSE A QUESTION TO STATE THE SCIENTIFIC PROBLEM.
Do heavier objects
fall faster than
lighter objects?

2. MAKE OBSERVATIONS With your
shoulder buddy, look at the objects at your desk.
Write down observations about your objects.

3. FORM A HYPOTHESIS Which object do you think will hit the
ground first? Why? With your shoulder buddy, write
down your hypothesis (your prediction that will answer the scientific question)

4. DESIGN AN EXPERIMENT
Hold both of the objects at the same height.
Release the objects at the same time. Let your shoulder buddy try.

5. COLLECT, RECORD, & ANALYZE DATA With your
shoulder buddy, write down data you collected from your experiement.
Examine, or analyze, your data with your partner.

6. DRAW CONCLUSIONS Was your hypothesis correct? Why or why not? Do heavier items fall faster than
lighter items?
