A series of videos demonstrating various simple, fun practicals and demonstrations that you can use to teach about gases

Each video shows how to carry out the demonstration and explains the science behind it. You don’t need any specialist equipment – all of the demonstrations use things you can buy in a supermarket.

Carbon from a candle demonstration video

Collect carbon soot from a candle to investigate changing materials with your primary students.

Fire extinguisher demonstration video

Investigate this topic with your learners

Use this demonstration as part of a class investigation on irreversible changes and the ‘fire extinguisher’, with accompanying classroom slides and teacher notes.

Put out a fire with a jug of carbon dioxide to demonstrate changing materials, irreversible reactions, and gases to primary students.

Leaky bottle demonstration video

Investigate this topic with your learners

Use this demonstration as part of a class investigation on air pressure, gases and the ‘leaky bottle’, with accompanying classroom slides and teacher notes.

Investigate gases and atmospheric pressure with the Leaky Bottle experiment.

Lava lamp demonstration video

Investigate this topic with your learners

Use this demonstration as part of a class investigation on liquids, gases and the ‘lava lamp’, with accompanying classroom slides and teacher notes.

Make a lava lamp to explore mixing liquids and more concepts in primary science.

Freaky hand demonstration video

Investigate this topic with your learners
