50 Easy Summer Science Experiments for Kids

May 13, 2024 By Emma Vanstone 19 Comments

Summer is a brilliant time to explore science outdoors with children. You don’t have to set up fancy experiments, even just looking at properties of plants and leaves or testing to see if different items sink or float in a paddling pool is great simple science for little ones.

Older children will love building bottle rockets , setting up chain reactions and making square bubbles.

I’ve compiled a fun list of our favourite summer science ideas from Science Sparks and many other fantastic blogs to keep kids of all ages happy all summer.

My DIY science camp also has some great summer science ideas, so check those out, too!
