Supah Planes

Does weight affect the distance of paper airplanes ?

Which is more powerful, water or earth?

This science fair is a really good idea. You gather about 6 materials you will test, such as cardboard, plastic, and house hold items. You should have 2 of the materials, ex. 2 pieces of cardboard. Then, you bury the material in earth, and with the other piece, you soak it in water. You leave the pieces in there for 1 week. See which one is more decomposed or damaged. I came up with this one by myself, so I think it's really interesting.

3 Liquids

Well, I never used this idea but I plan on to this year, take 5 liquids, 1 plant but get 3 of the same and test to see which one makes the plant grow the most. You take the same amount of liquid and pour it into the plant every day and record it.

Does gravity make us lighter in weight on the moon?

I thnk it's pretty cool

I haven't done it myself but it sounds pretty cool. Detect Iron in Cereal - This science experiment shows that there is more in our cereal than just whole grains! • 1 Tall Narrow Glass • 1/2 cup water • 2 Cups of Cereal - Total Brand works best • Magnet • Blender 1. Put Cereal and Water into blender and blend until cereal is finely chopped. 2. Pour mixture into Tall Narrow Glass. 3. Run Magnet along side of glass and watch to see if any of the mixture is attracted to the moving magnet. Iron particles will move with the magnet as you run it along the glass. Turn it into a science fair project! Use the scientific method: Develop a hypothesis first and then test it by running this experiment. Here's a sample hypothesis: Popular cereal brands are fortified with small iron particles just as the labels say.

Carbonated Soda

Does Temperature affect magnetsim?

—Guest Laura

Geiger Counter Ghosts

I saw on that Ghost Hunter show that paranormal activity may be detectable using a Geiger counter. Are there areas in a building where the background radiation is higher than elsewhere? Does the background radiation seem different when paranormal activity appears to be occurring?
