Boiling and Freezing Points Lesson 1: All Hail the Freezing Point!

Unit 4: Physical Properties: Molecular Arrangement and Phase Changes
Lesson 10 of 12

Objective: The students will be able to explain how solutes and pressure affect the boiling/freezing points of liquids and describe the energy transfer that occurs during phase changes.

Big Idea: These lessons have text strategies, writing instruction, discussion techniques, and science content! Students blow up a bag with butane, make water boil at 50 degrees, and make water freeze instantaneously as they explore physical properties!
