Overview

In this lesson, students will be able to explain that cooling water can change it to ice and that heating ice can change it back to liquid water. Students will be able to explain that this process can also happen to other substances. Students will also be able to explain that heating a substance makes its molecules move faster and cooling a substance makes its molecules move slower. The lesson can also be used to lay a foundation for learning about changes in state and chemical changes which can be further developed in later grades.

SC15.2.4
Provide evidence that some changes in matter caused by heating or cooling can be reversed (e.g., heating or freezing of water) and some changes are irreversible (e.g., baking a cake, boiling an egg).

Knowledge

Students know:

Characteristics of materials before heating or cooling.
Characteristics of materials after heating and cooling.
Characteristics of materials when heating or cooling is reversed.

Skills

Students are able to:

Analyze evidence to support a claim that heating and cooling causes change in matter.

Understanding

Students understand that:

Heating or cooling a substance may cause changes that can be observed. Sometimes these changes are reversible and sometimes they are not.
