Do something in biochemistry. Extract DNA from Tomatos, it can be done with kitchenware. You can explain in your report how the extraction worked (the principle behind each practical step) and the general chemical composition/structure of DNA as well as its significance in the history of science and todays technology.

Hello,
If you find difficulty in your project then why don't you try Evaporation. In that you have to use very less effort and basic thing's like water, heat burner and pod.
