A) a wooden box with holes
B) a rock and cup of water
C) ice in a glass and a thermometer

Answer 1

B. a rock and a cup of water, this will show the water displacement which is showing a increase in volume due to the rock taking up space in the cup of water

Answer 2

I think the correct answer from the choices listed above is option D. If you wanted to describe an increase in volume to your class, the object that would be best to use is a soccer ball and a pump. Adding more air to the ball will expand the ball. This is adding more internal pressure to the ball.
