Can Boiling Make Something Freeze?
Use boiling as an avenue for freezing. Young scholars watch as liquid nitrogen removes heat from the ingredients for ice cream. As this happens, the nitrogen boils and the ice cream freezes—all in the same container. A little science magic!
Curated OER
Heat Transfer
The students construct a heating curve and explain its components. They perform calculations. They review phase changes and quantify Energy differences. They review phases of matter and their energy content.
Curated OER
What Is the Freezing Point?
Students remove heat energy and determine how it causes a phase change.

Chemistry E3 Lesson Plan
Ninth graders perform a series of experiment to investigate heat transfer and phase changes. In this physical science lesson, 9th graders identify and calculate the different subatomic particles. They explain the importance of scientific...
Curated OER
The Chemistry of Ice Cream
Students investigate the effects of temperature change on phase changes. They explore the effects of changes in freezing point and incorporate the law of conservation of energy. They utilize these concepts to make ice cream.
Curated OER
The Same But Different
Fourth graders identify the characteristics of a simple physical change. They describe objects by the properties of the materials from which they are made. Students discuss the different states of matter and their distinct physical...
Curated OER
Condensation Lab
Young scholars investigate condensation in the lab. In this chemistry lesson, students explain molecular motion during phase changes. They relate this observation to Earth's weather conditions.
