Intro Tab:

1. How can you use a block and the other tools on the Intro tab to determine the density of the "Oil"?

2. Determine what forces act on an object when is it in a fluid. How are the forces similar and different when the object sinks, floats immersed in the fluid, and when it is only partially submerged.

3. Give specific examples that you could use to explain what buoyancy is and how an objects weight can appear to change when in a fluid. Make sure to include situations where the object sinks, floats immersed in the fluid, and when it is only partially submerged.

Playground Tab:

4. Explain how you can use the information about the block and the fluid to determine if the block will sinks, floats immersed in the fluid, and when it is only partially submerged.

5. How can you determine the apparent mass of an object if you know the density of the object and the density of the fluid?

6. Challenge: Explain how an object that is more dense than water can be kept afloat by placing it on an object that is less dense than water.
