This FUN addition to a heat and thermal energy unit demonstrates that particles move farther apart when heated. Also a convenient way to include "Building and Revising Models" of the NGSS Science and Engineering Practices as you teach heat, thermal energy, and particle motion.
This simple activity can be used as an easy take home laboratory and counted as a homework assignment, or modify it to be done in class using ice instead of a freezer. Students follow a simple procedure with a bottle (soda plastic, glass - they all work) and a coin, and then observe thermal expansion in action! They then fill in blanks explaining what happens in terms of particles. Each sheet contains 2 assignments, so you make half the copies and cut the papers in half. Assignment contains instructions and quick concept review.
