Science Fair Ideas?!?
What are some really good and creative ideas I can use as a science project? Something creative and impressive. Anything that would fall into the category of something a high school student would do (I'm in 8th gade) that would impress my teacher. I don't mean models, I mean something I can actually test, and have a hypothesis towards. Please list more than one idea. Thank you all in advance.
(The deadline for ideas is tomorrow).

Would you like to lear a little about electronics and computers while you're doing your project?
If so a company called DATAQ gives away a free data logger worth $29 to students.

A datalogger is a device that lets a computer read a small electric voltage (0 to 5 Volts DC) from several sensors and record the readings to a file. These measurments are done at a periodic interval that can be as frequent as multiple times persecond to once every few minutes depending upon how it is setup.
With a datalogger and a handful of resistors and thermistors you can record several temperatures at once then use Excel to process and chart your data. I recommend using thermistors as they are a cheap and easy way to measure temperature. You can then perform experiments with insulation and heat sources so that you can demonstrate how effective different types of insulation are effective by gathering data on how fast things in insulated boxes heat and cool. (Compare sensor temps inside and outside of the box over time)
