More Science at Home Experiments…

On this page we’ve grouped our experiments into themes – what do you want to find out about? Maybe you’re raiding the kitchen cupboards for chemicals? I mean… ingredients! Or perhaps you’ve noticed that water is pretty special and you want to find out what makes it so unique? Or maybe you love anything that moves or oozes or flows!

Let us know any suggestions you have for experiments!
