The children will find how easy it is to do a proper, exciting scientific experiment.

The reaction between a carbonate and an acid produces carbon dioxide gas. If this reaction is carried out in a closed container, the reaction will blow the lid off! Let’s investigate this further.

Vitamin C tablets contain these two substances but, until mixed with water, they are not able to react with each other.

Everyone will be shown how to do this simply and safely. Then they are given their challenge: It seems that the explosion is bigger if the water is hot than if it is cold. Why so? And how much so? They have to work out how they are going to carry out the experiment. They then do it, using water at different  temperatures, recording their results each time.

When everyone’s results are put together. they should give a pattern to show how temperature affects the speed of a reaction.

10.30am, 11.30am, 12.30pm
