Magic tricks revealed using chemistry

Some magic tricks, such as disappearing ink or candles that won't blow out, can be explained by chemistry. In this clip, three classroom chemistry experiments demonstrate that some familiar magic tricks rely on acid-base chemical reactions, and the properties and behaviour of gases. Watch closely if you've ever wanted to ...

Reactions and rates

This is an interactive resource in which students explore what makes a reaction happen by colliding atoms and molecules. The can design experiments with different reactions, concentrations, and temperatures. Students can use the potential energy diagram to determine the activation energy for the forward and reverse reactions, ...
