Air has Weight

This experiment comes from a question sent to me a homeschooling mom named Elaine. It is based on a "classic" experiment often seen in textbooks to show that air has weight. While it starts simple, it takes some twists along the way that often cause people to misunderstand what is actually happening.

A Cup of Cold

This experiment comes from some research I am doing on "Science With Your Refrigerator," but it has its roots in my childhood. You may recognize some of your childhood too.

Air Space

There are only two more days before we head for New Zealand. I am looking forward to the farm, the beach, seeing friends, and the food. It will be a LONG flight, but I am even looking forward to that. Most of my packing is done, and I am down to the "what did I forget" stage.
