Where's the Air?
Air can be a big brain bender for first grade scientists. After all, you can’t see it, you can’t taste it, and if you try to reach out and touch it, people might think you’re a little nuts. So how can your child tell it’s real?
Some very, very smart people have wondered the same thing for centuries. One way we can tell that air exists is by observing some of the things it does. Air can fill a balloon, for example, and when it’s in the form of wind, it can move leaves and blow your hair around. Here’s a quick, fun experiment that your child can do with just a few things from around the house.
