Is a volcano projects is good for 8th grade?

Question

if not then tell me any other pleaseeeeeeeeee.........

Answer 1

No, that has been way overdone*, and it's at a level I associate with a bit lower than Grade 8. *I assume you mean the project where you create a "working" volcano using baking soda, etc.

Google "science fair project ideas" or similar... for example:
