50 Summer Science Ideas

You don’t have to set up fancy experiments outside, even just looking at properties of plants and leaves or doing a bit of sinking and floating in the paddling pool is great simple science for little ones. Here are some of our favourite Summer Science ideas from Science Sparks and lots of other fantastic blogs.
