A demonstration of how a periscope works that you can do for yourself!

A demonstration of reflection of a ray in a plane mirror.

Experiment on how to find the density of a solid or liquid.

An experiment on how to demonstrate Ohm's Law in the lab. Ohm's Law is the relationship between the voltage (potential difference) and current in a circuit.

An experiment on how to demonstrate Hooke's Law in the lab. Hooke's Law is the relationship between the extension of a spring and the force applied.

An easy way to demonstrate that light travels in straight lines.

An experiment to show heat transfer by radiation in different colour cans.

In this experiment we show you how heat is transferred by conduction using our conduction apparatus!

This is the basis of a mercury or alcohol thermometer, how a liquid expands when heated and contracts when cooled.

An experiment to show the expansion of a solid when heated using the ball and ring apparatus.

In this experiment we show you the expansion and contraction of a gas when it is heated and cooled.
