About the Experiments
These demonstrations and experiments can be performed with a relatively simple and inexpensive vacuum system...a system that can be found in many high school science departments. It's use, however, need not be limited to the high school level, but could also benefit science education at all levels. For example, a second grade teacher might use it to excite students about the world of science (blowing up a balloon or marshmallow in vacuum). A seventh grade science teacher might find it very useful in demonstrating a scientific principle (gravity and air resistance with a falling feather). Or an advanced high school physics student could use it to perform a laboratory experiment (determination of the size of a gas molecule from thermal conductivity).
