Science is really cool. There are so many amazing things in this world of ours. So many science experiments for kids that just make me stop and say, “whoa” … or “wow” … or “What the …!!” (depending, of course, on my company).

Children, as we know, are naturally curious. They naturally want to learn all about the world around them. This is part of the reason I adore doing science experiments with young children. Hearing the “whoas” and the “wows” (but not “what the…” thankfully) from my little ones is just awesome.

These are easy science experiments for kids that will do just that.

But before we get started, I think you’ll love this fun science experiment where we turn milk into… plastic?! Grab the step-by-step instructions delivered to your inbox so you can start on this fun activity right now:
