1. Activity 3

2. 1.) Write The Question You Are Investigating
How does the mass of an object affect the amount of PE and KE it has?

3. 2.)Write What You Think Will Happen
If we drop 2 spheres of different masses from the same height, then the __________ sphere will…

4. 3.) List The Materials You Will Use
2 Spheres
Meter Stick and measuring tape
Spring Scale
Cloth bag
Sand

5. 4.) Write The Steps You Will Take
Weigh the spheres
Drop a heavy sphere from 1 meter height into sand and measure the indent it makes (x3)
Repeat step 2 but with the wooden sphere
Record data

6. 5.) Make A Chart To Organize Your Data
Trial 1
Trial 2
Trial 3
Average
Wooden Sphere
__5__ g
Steel Sphere
__70__ g
Observations:

7. Rewrite your hypothesis to make it correct
Conclusion
Claim: Write your hypothesis if correct OR
Rewrite your hypothesis to make it correct
I believe that if…..then….

8. Conclusion
Evidence: Explain what your data tells us (patterns you see)
From the experiment, the data showed that…
Also include observations
I noticed that…

9. Conclusion
Reasoning: Make connections from what you already to know to what you just learned
Key words/ concepts to include:
Potential Energy
Kinetic Energy
Gravity
Mass
Same mass/ different mass
Same heights/Different heights

10. Conclusion Future: What would I do differently next time and why?
If I were to do this experiment again I would …. because….
