Types of matter: solids, liquids and gases

Select samples from an outdoor setting. Magnify the substances to atomic level so that the particles they consist of can be seen. Sort the substances into groups based on how the particles are arranged and how they move. Classify the substances as solids, liquids or gases. For example, classify argon as a gas and ice as ...

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 ...
