Physics EE help

[niceperson91]

Hey guys,

Since I am just starting my EE process, I would like help from all of you. I am doing my EE on Physics (i am in physics HL), and I cannot decide what topic to choose. So, can someone list down mutiple suggestions on what topic/question I should do. You can tell me what your friends have done or recommend me any new topic worth exploring.

Thanks

P.S: my teacher recommended me to do it on sound and temperature, however, I want to hear some other interesting topics before I make a final choice.
