um and also i can't just research something. i have to experiment, and the data can't be too subjective.

oh yeah and this project determines whether my teacher is going to recomment me for GT science in high school so it has to be impressive.

Answer 1

You could try to do something involved in the environment
such as

Effects of global warming

Alternative energy sources
-Ethanol - How it works (kinda a plant thing tho)
-Nuclear - why there are no CO2 emissions
-How a hybrid car works

Feel free to contact me if you have any questions about these topics and I can help with finding information if you like

Answer 2

Use GPS to gather location and altitude data. Solve the problems of human sensing of heart rate and respiration and get them into a small computer via bluetooth along with the GPS data. Correlate the sets of data for people of various ages walking, running, or biking in an area with various changes of altitude over varying distance.
Figure out how you would use what you have developed to record information on pulling or carrying loads by people.
Take the idea and work with machinery to measure loads and horsepower - a self propelled mower pulling a trailer on various surfaces (grass, mud, dirt, pavement) and various slopes.
