What would be a good science fair project?

• Okay so, the science fair is next month but my teacher told the class to get started. I dont't know what to do, I was thinking of doing a project about eyes and how they work witch is very interesting, I read like a whole page but then I was thinking to do the solar system people always do that for the science fair though.

  Last yr erin did a project on does caffeine make ur haeart rate go faster after excersicing? She had 4 friends drink coffee, do an excersice. like running or catching a ball or jumping jacks. then she did the same with soda and then with no caffeine at all all excersises are seperated daily to get all the caffeine out of your blood. good luck christa!!!
