Homemade Fossil Dig

Fossils are what lead me into my science career, and I still enjoy finding them. If you live near a place where you can dig for real fossils, you should definitely give it a try. If you do not have a fossil site nearby, you can simulate the experience with this simple activity.

Making a Solar Still

Imagine for a moment that you are stranded in the desert, and running short on water. Or imagine that you are in a boat far out at sea, surrounded by salt water, but no fresh water to drink. Is there any way you could use some science to get something to drink? Of course there is!

Making a Scale Model of the Solar System

Take a moment and imagine our solar system. Think about what it would look like if you were moving through it in a space ship. Once you have that image in your mind, get ready to replace it with a much more accurate image.

Our solar system is a very large place, and most of it us empty space. Because of the way it is shown in textbook drawings, on TV, and in movies, most people have trouble imagining the actual sizes and distances of the planets. This simple activity lets you use a scale model to visualize those sizes and distances.
