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 ...

Projectile motion

This is an interactive resource about projectile motion. Students use a simulation of a cannon to fire various objects. They can set the firing angle, initial speed, height and mass, with or without air resistance. Students are encouraged to make a game out of this simulation by trying to hit a target. This interactive ...
