School Science Projects

i want to make a science project for a scholarship competition. however, i do not have money to buy microscopes and things like that. what is an interesting idea (high school level) that does not require those items.

A very common science project for young kids is making a volcano out of cardboard and using baking soda to make it erupt.

But what is this teaching the kids? And in what way is it science?

This is NOT how a real volcano erupts. It does not model a real volcano in any way. It does not demonstrate any geology or siesmology. It does not use the scientific method to investigate anything. It seems to me that this is just an art project. Why do so many teachers allow it to be called “science”?

okay so for school we have to do a project about minerals. i am in 7th grade by the way. please explain this in kindergraden language. (we have science buddies and have to explain it to them).

what is a crystalline structure?

use easy words. they wont understand big words.

thanks
