After a specified amount of time, the children can remove the lights and measure the remaining water to see which bulb evaporated the water most rapidly. By attaching a low voltage bulb to a potato, middle school student can safely learn to create an electric charge.

This science project is recommended for children from grades 3 through 8. Student will take a penny and wrap a piece of electrical wire around it. Then they should wrap the other end of the wire around a galvanized nail. Once this has been done, the kids can cut a potato in half and insert the penny into one half of the potato and the nail into the other. Students will then attach two alligator clips to the wire and the opposite ends of both alligator clips will be attached to the end of a small light emitting diode LED.

If the project is successful, the LED will light up. Fresh potatoes have been found to be most effective in this experiment. A cool science project that children may find interesting is making a thermometer. By taking a water bottle and filling it with 25 percent water, 50 percent rubbing alcohol, leaving 25 percent empty, and then placing a straw inside, children can create a device to measure heat levels in the water.

Be sure the children use tape or modeling clay at the top of the bottle to secure the straw in an upright position. When the bottle is placed near a heating device you should begin to see the liquid rise up through the straw as the water becomes warmer.
