School Science Projects

I am in middle school but i need a high school level science project. I was thinking about doing something related to plants. I have this summer to do it. Does anyone have any good ideas?

I’ll only be a freshman this year, but I’m willing to try up to senior level projects.

I do not need a whole science project, Im just out of ideas and my science teacher has rejected all my other ones. Something possibly with batteries.
Im out of ideas and I just need some. My teacher has rejected all of my other ones. It has to have a hypothesis/procedure style to it.

I would prefer something that has to do with psychology. The year before I did a project about prejudice. Handing out surveys would be fine. I just need ideas because I can’t think of anything!

Does anybody have any ideas for a high school level science project?

I need to do a science project for Physics, but our project doesn’t have to deal with Physics.

He’s giving us around 3 weeks to complete this project.

So he doesn’t want us to do a project on plants or animals.

Any ideas?
