Make meringues with your first grader and see how states of matter can transform before your very eyes. Here's how:

Did you ever think you could make colors disappear right before your eyes? This science experiment is just like a magic trick: now you see it, now you don't!

Water can go from solid to liquid to gas...but how does popcorn go from kernel to snack? Invite your first grade scientist to find out.

Play this flashlight game with your child to teach him about objects that are transparent, translucent, and opaque.
