Any suggestions on myths I can bust for a 12th grade science project?

How many times has your Mom told you. "Don't go outside (in the winter) with wet hair.... you'll catch a cold." Well this is just false, colds are caused by viruses and nothing else.

One can swing buckets of water around on a rope or drop baseballs and golf balls from the top of a ladder. This disproves midieval myths though, and hardly anyone thinks in terms of the earth being flat anymore.
There is still an "urban legend" which persists in the modern world. Its the notion the moon landing was a hoax. This is easy to disprove if one understands something known as "triangulation". The source of a radio transmission can be found by observing its direction from two separate points. If the moon landing was a hoax, triangulation could easily show the source was, say, a movie set somewhere in Hollywood, California. Simply calculate the triangulation results from some point in California and compare the numbers to what one would get if the source was from the moon. The only way the results could be similar was if the moon was lined directly up behind Hollywood. The angles would be different, though because the moon would be very much farther away. One other difference is that the moon is moving. Hollywod does not move.

Here's an idea. Check out to what point in a mass the force of gravity is measured. You will find that this force is said to increase continually to the center of a mass. Then determine the acceleration of a mass if it were 400 miles from the center of our sun. You will find that were a mass to be in that location it would exceed the speed of light in one second. A mass cannot exist in a location where it would be exceeding this speed in one second. Is there an 800 mile location within the center of our sun where mass cannot exist? In our own planet this distance is 0.716 miles from the center.
At http://360.yahoo.com/noddarc there is a short writing entitled "The Time Structure of Our Solar System" that you may have an interest in. "Our (Earth's) Very Own Black Hole" may be of value.
