School Science Projects

I have to do a science fair project (write a lab report and everything) but I keep coming up point blank. I’m in 7th grade but my school is rather advanced and I’d like to do a somewhat advanced project. Nothing too hard for a middle schooler but does anyone have ideas? Other project ideas are showing the difference in plant growth under fluorescent and incandescent light.

Want some science experiments for class6 students.

We aren’t very artistic. Nor have any experience with crafts. These seems like crafts. Good instructions - just every time he does one - it seems it isn’t very great looking and keeping supplies for this is hard.

i need of something useful such as geometry,arithmetic,mensuration etc
