The grade is up to how diligent you are. Below are some sites that have lots of science fair projects.
What is the project on
When I did my Science Fair project, I was asked how I did the project, How I used my research, and how it applied to real life. If you do your project well and give a good explanation to the judges, it should be a breeze.Here is a good website to help with the judging!! :)http://www.sciencebuddies.org/science-fair-projects/project_judging.shtml
Yes. It is a great science fair project. Easy and fun
a good science fair project about energy is a water cycle and would be put in the Energy Awareness category
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, there are plenty of helpful websites online that can give your child an idea for a science project. Check out Science Buddies at www.sciencebuddies.com

A good idea for a science fair project is to do a project where you test which plant food will be the most effective. also, you can do which orange has more vitamin c. and who is the fastest kid in your grade or best speller.
Don't. Its...not a good idea.
Sure would.
