I’ve found my 5 year old to be incredibly curious at the moment, always asking questions and wanting to know how things work. Even something as simple as a rain gauge has been VERY exciting for her. With that in mind I’ve pulled together a list of great science experiments for kids of all ages! The age ranges mentioned in this post are just a guide, most science is fun for all ages if you tweak the activity a little bit.
I’ve also got a couple of science books available if you fancy taking a look.
