PLEASE HELP ME IM IN A BIG HURRY

Well the only thing that comes to mind for me, is when I was younger and we had to do a science fair project. We did a solar system, and it was four of us partnered together. We each collaberated and took different parts. I was the one who had to find materiel for the solar system. The others did the colors, and how they were going to make it move around and rotate.
