Although my teachers generally discourage from a EE in science if you are doing 2 HL (bio and chem), I know that they are the subjects which I am very good at and I actually love studying. I have been debating over my ideas for topic choices over the last couple of days and I would like some help in deciding which topics are more appropriate for EE. I have not quite composed a research qn yet but these are the general ideas. 1. The effect of sunscreen and its ability to decrease the intensity of the radiation - i would perform this experiment on plants not humans obviously for the ethical reasons 2. The rise in acidity of soil due to acid rain and the impact it could have on on the growth of plants 3. How chemicals commonly found in acne products kill and inhibit the growth of bacteria Thanks for your help!
