Centre Avenue fourth-graders in Kirsten Miolan’s class are studying physical and chemical changes.

They began by watching videos, reading informational texts and taking notes in a Tree Map to determine the differences between a physical and chemical change. They then took what they were learned and combined it with their social studies Colonial Times unit. Students read “The Story of Butter” to find evidence of either a chemical or physical change. They learned that making butter is a physical change, but decided that they needed some proof. Working in small groups, the class filled jars with heavy whipping cream and took turns vigorously shaking them. This motion caused the cream to turn into butter! As a result, they could see that a physical change had occurred and there were no signs of a chemical change.
