Heat changes everything

In this learning sequence, students explore a simple particle model for matter, heat energy and thermal expansion. They apply their learning to the context of expansion and contraction of rail lines and investigate ways that this is mitigated in real situations involving rail lines. They subsequently explain this to young ...

Expansion and Contraction

This is a problem-solving activity in which students are engaged in a challenge is to control virtual bridges using expansion and contraction so that a car can pass over them. In so doing they learn about the expansion of solids, liquids and gases when heated is applied. Students need to understand how a bimetallic strip works.
