This presentation by Keith Burrows is designed for teachers to use in schools or with their local community.
It contains reasonably ‘heavy’ science aimed at senior students or serious adults.

A ‘lighter’ version is in the pipeline and will be put on vicphysics.org soon. In the meantime, for younger students some sections of this presentation could be omitted.
