Discrepant Activity for - Floating - Density - Capacity concept assessment


Draw a picture or show a photograph of a container of water with different objects - floating, sunk, and in between the top and bottom.



Show the pictures of different objects floating with all parts above the water surface, half above and half below, submerged but not on the bottom, and on the bottom to the students and ask them.

Which objects are floating?

Which objects are sunk?

What are these objects in between doing?

What else might the objects be doing?

What about the one on top? Could it be doing anything, but floating?
