Changes Caused by Cooling
Supporting
TEKS Objective
The student is expected to predict, observe, and record changes in the state of matter caused by heating or cooling.
Essential Understanding
The student knows that matter has measurable physical properties and those properties determine how matter is classified, changed, and used.
Science Background
Freezing: Purdue University (website) - Illustrated explanation of the differences between, and structure of the particles in liquids and frozen solids, with information about the processes of freezing and melting.

Elaboration Lessons and Extensions
Safe Food Preparation: BioEd Online (website) - Students learn about different states of matter by making ice cream.
Assessment Ideas
Have students predict and record temperature changes, and also observe changes that occur when liquids (water, milk, soft drink, syrup, etc.) are cooled in a freezer. This investigation can be done in class or at home.
