Hi everyone!!! My names Paola, on my last year of High School. I am actually looking for a good investigatory project for Physics that I can invent. I actually want it to be something related to solar energy, but my teacher doesn't want it coz its too cliche. Anyone here who can recommend some good IP's? Thanks to anyone who can help!
