Can anyone tell me about the solar system hypothesis and everything else for the science fair project?
The most you can give anyone is 10 points if you rate the answer 5 stars. At least you are not waiting until the last minute. You can do web searches for the hypothesis of the solar system. Your Problem would then be how to duplicate the hypothesis or at least part of it. Your Materials would be whatever you can use to create some of it, Procedure is your steps for using your Materials, Data is recording what your Procedure shows, and Result is what you find out. I suggest you get to know the most successful student in your class and get some pointers from them, or ask your teacher to help you get started.
