This video shows students the effects of matter changing phase. Changing phase simply means when matter changes from a solid to a liquid, or from a liquid to a gas. It can also change phases backwards from a gas to a liquid then to a solid. The follow video demonstrates this while at the same time keeping the students aware of the scientific method.

STUDENTS: Show of your learning skills by following the instructions on the video and asking your parents what they think will happen.
