The number of obese and overweight people in Amercia is at an all time high. Never before have the health risks of being obese been so profound and in your face. Suppose you made a science project which helped the obese to lose weight? After all the health risks of being obese include everything from developing diabetes, hypertension and high cholesterol.

So what kind of science project can involve obesity? You can study the factors leading to obesity in your project report. A section can deal with the health hazards associated with being obese including fatal cardiac arrests. The display board can include the “work out the ideal weight” charts as per your height. There can also be a list of things to do to become fit again.

And may be you could design a machine which helps you exercise and stay fit. It can be a simple stepper which works on the principle of an escalator. It may not even need to be motorized. It can work on the power of the human stepping on it. Much like the cycle that runs on man generated power. All you will need to do is get the basic structure soldered in shape and put a rubber sheeting on top. Check out more interesting displays here.
