If your fourth grader is obsessed with all things glow-in-the-dark, then here's an activity that will really light up her imagination!

In this sound experiment children listen for differences as they tap on a bag of air, a bag of water, and a wooden block held up to their ears.

Let your fourth grade chef mix up butter and sugar with scientific principles about different states of matter, and get delicious toffee, too.

Air invisible; it doesn't make sounds; you can't pick it up and throw it. So how do we know it exists? Help your second grade scientist figure it out.

Think you can blow up a balloon without using your mouth? This isn't just a cool trick, it's also a great way to introduce chemistry and biology concepts.
