Here are some lists of brainstormed ideas for science projects.  Remember, the best project is one that interests you and builds on what others have done.  Use these ideas to stimulate your imagination and create ideas of your own.  Add to or improve one of these ideas, or come up with your own.

These project ideas are simple.  You would hopefully develop it more fully.  For examples of completed projects, check out these Sample Projects.
