hey people! so im an IB student who has chosen to do his extended essay in physics so ive done all the experiments that i wanted to do for my topic. but now im just concerned if its too simple (is that something they consider?) well anyway, my case is that i investigated the effect of temperature on how high a ball bounces at a few different temperatures which gave me some nice results. but i wanted to make it a bit more specific and my teacher suggested to investigate the efficiency of bounces (measure how high it bounces the first and second time and see how much lower it bounces each time). thats a nice idea but where is it going tho? does that mean anything if the efficiency is lower? thanks a lot!
