This resource contains lessons plans containing instructions and teachers' notes for an activity based on a chemical reaction that occurs when a soluble aspirin tablet dissolves and the fact that oil and water do not mix are used to create a model of a lava lamp. Students have fun while they learn about density of fluids. ...

Measure the pH as you gradually add an acid to a base, or vice versa. Learn how to change pH up or down. Adjust the pH in an aquarium to help keep the fish healthy. For example, return the pH to a suitable level after soft drink has been spilled into the water. Remember, all acids and bases including the dilute solutions ...

Ever wondered how fireworks are created? In this clip, pyrotechnics expert John Conkling describes the chemical and physical components of fireworks, and demonstrates many coloured explosions in a laboratory. Discover that a fireworks display is a chemical reaction between an oxidiser such as potassium nitrate and a fuel ...

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 ...

• TLF-IDL8489

Test your understanding of the pH scale by classifying solutions according to whether they are an acid, neutral or a base. Use results from the solutions tested using red litmus paper, blue litmus paper, the indicator phenolphthalein and the addition of a piece of metal (Zn) to help you classify them. Your preliminary classification ...

• TLF-IDL5818

Measure the pH as you gradually add an acid to a base, and vice versa. Learn how to change pH up or down. Adjust the pH in a swimming pool to ensure the water is safe for people to swim in. For example, return the pH to a suitable level after heavy rain. Remember, all acids and bases including the dilute solutions used ...
