What is the project on
The Effects of Different energy drinks on Plant Growth
Yes. It is a great science fair project. Easy and fun
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.
I did a science fair project too. I won. Anyway... If you are doing a project, you want to rove something, not just do a demonstration because that is NOT what they are looking for. I would do something that you are capable of doing and if you don't know what to do . Then, do something like wind energy or robots and maybe you could win your science fair project.

For a science fair project you can do estimating solar energy potential of a house using solar lights

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.
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
Decomposition, energy, light, electricity, and photosynthesis are all good science fair topics
