1. SC.8.P.8.2 Differentiate between weight and mass recognizing that weight is the amount of gravitational pull on an object and is distinct from, though proportional to mass.

2. Question
How does the mass of an object affect its weight?

3. Hypothesis
If the object is changed and the mass and weight is measured then the mass and weight will be _________________.

4. To teach 8th graders the difference between mass and weight.
Rationale
To teach 8th graders the difference between mass and weight.

5. Materials List
4 smaller items from your backpack
1 balance
1 scale

6. Procedures Gather materials
Take 1st small object and place it on the balance.
Adjust the weights to find the mass of the object.
Log the mass on data table
Repeat steps 2-4 with 3 other objects
Take 1st small object and place it on the scale
Log the weight on the data table
Repeat steps 6-7 with 3 other objects

7. Data
Object Name
Mass
Weight

9. Conclusion What is the difference between mass and weight?
What misconception or confusion might exist about the difference between mass and weight?

11. Follow Up
Why do you weigh less on Mercury and WAY less on Pluto if your mass stays the same?
