Depending on what topic your teacher has given you, you should make your project. If the topic is not specified and you are asked to make project in physics only then you should go through the topics in physics in your syllabus. You will definitely find some topics providing you with some good and innovative projects. I would suggest to apply your mind and innovation in the project with dedication. This will help you to innovate new projects by your own without much difficulty and you will start enjoying making good projects. I hope you will come up with impressive projects.
All the best!
