If you can come up with a good project that involves cats, I don't see any reason why you shouldn't be able to do your science fair on cats.
you could start off with something basic like a calculator or a flash drive
It depends on what the project is on.
What is the project on
this is a very good science project
"A Sweet Exploration: Investigating the Effects of Chocolate on Melting Rates"
a picture or video would be good for the audience, and if you know how to spiral the ball, demonstrate.
A project about what is the healthies drink in the world
You can do the Coke A Cola and Mentos project.
This question of are pulleys a good science fair project is up to the person choosing the project. If you like it then you should do it. If not then don't do it. The choice is up to you.
Yes. It is a great science fair project. Easy and fun
