Collect micrometeorites from indoor and outdoor sources.
Does the number of turns of wire in an electromagnet affect its strength?
The purpose of this experiment was to find out if the number of wire wraps will effect the amount of iron filings an electromagnet picks up.
How to build a levitating train using magnets
This is a great demonstration of like poles repelling each other. We have a platform which floats above a pair of magnetic tracks, and can be gently pushed to one end or the other. This is similar in concept to the MAGLEV trains which are being worked on in Germany, Japan and France
How does a bar magnet's field interact with the earth's magnetic field?
The magnetic field around a permanent magnet, like the gravitational field around a massive object, is not only invisible, but hard for students to comprehend. With no concrete experience to draw from, they tend to ignore this basic concept, or at best, memorize facts about it. This activity shows how to map a magnetic field, and to find how a bar magnet's field combines with the Earth's magnetic
How to build a magnetic linear accelerator
This very simple toy uses a magnetic chain reaction to launch a steel marble at a target at high speed. The toy is very simple to build, going together in minutes, and is very simple to understand and explain, and yet fascinating to watch and to use.
How to build a lightning storm detector (Franklin's Bells)
The toy is a high voltage motor that acts like a bell, with a clapper that bangs furiously from one can to the other and back again, sometimes several times per second.
Do different types of sunblock have different protection strengths?
I wanted to know if SPF matters when you buy sun block. For example, does a CVS brand 30 sunblock work better than a CVS brand 15 sunblock? I also wanted to know if higher priced sunblock works better than lower priced sunblock of the same SPF? My hypothesis was that the higher the SPF the better it would protect and that higher priced sun block would work better than lower priced.
How does temperature affect the rate of growth of algae?
The purpose of this experiment was to determine the effect of a certain species of algae when they are growing at different temperatures.
