The thesis is not as mysterious as you said, basically it has nothing to do with people's knowledge, education and so on, but it has something to do with people's observation, understanding and thinking.

Writing a thesis is generally divided into four stages: finding problems, putting forward problems, solving problems and practice testing. Finding the problem is the most important stage, and only finding the problem can pave the way for the final solution. The quality of solving problems is related to this person's knowledge, talent and experience. Note that an important feature of the paper is novelty. If the problem you said has been solved by others, your problem is meaningless.

You can do a lot of high school knowledge. I think your physics teacher is a very high-level person. He has jumped out of the stage of giving you homework and started to ask you questions and solve problems on his own initiative. So please do as he asks.

You must have made mistakes in the process of learning. The connection and difference between right and wrong practices are good materials. You might as well try!
