Gregg's Magnets and Electricity Lab is a set of demonstrations designed to render clear the sometimes obscure but extremely interesting relationships between magnetic fields and the movement of electrons.

This presentation complements the requirements put forth by the province of Ontario for Grade 3 Science and Technology curriculum.

Gregg says: "I feel it's important to answer the question 'What is the big deal with magnets? So they stick to things and push other magnets away. So what?' By allowing kids to move steel balls through a tube with a magnet, and by then demonstrating the similarities between this exercise and the moving of electrons through a wire with a magnet, they encounter many uncommonly perceived bridges to an understanding of the world we can't see."

In this show, energy and signals (vibrations) are generated, transduced, transmitted, and reproduced.

The topics of resistance, ionization of gasses, and electrostatic potential are also introduced.

This show includes audience participation - circuits are actually built using, as resistive elements, chains of kids holding hands.
