Lesson Plan

Changes Caused by Heating and Cooling

Curated and Reviewed by Lesson Planet

It's heating up—and cooling down—in here! A hands-on lesson plan allows learners to experiment with melting and freezing butter to observe changes as a substance transitions between liquid and solid form. They also view an animation that describes the molecular structure of the liquid and solid material.
