We have been learning about chemical and physical reactions. We know a physical reaction is reversible (this means you can change it back), A chemical reaction is irreversible (this means that you can’t change it back).
We have completed a number of experiments to investigate the effects of mixing different chemicals.
If there is a chemical reaction we know one of the following will happen: changing colour, temperature, fizzing showing a gas has been released and a smell been given off.

We made bath bombs.

We made lava lamps .
