School Biology experiments and demonstrations

On this page, you will find a list of fun experiments and demonstrations that are suitable for a school science lab or possible at home. Do not assume that they are safe! Most will have some sort of safety advice on the page but the absence of written precautions does not mean that you can just plough ahead. If you are an adult, you should use your own judgement. If you are under 18, you should ask the advice of your teachers or parents.
