I used the paint program to take the portion of the solar system that we would be workin with. We are only working with the first five planets as of now and I thought that it would be good not to over whelm the children and put all the planets on the screen at once. The file type that I saved the graphic under was JPEG (*.jpg,*.jpeg,*jpe,.jfif). The size of the file is 20078 bytes. I went to yahoo images and found numerous images that could have been used but I thought this one has the best color and would be the best to crop and get what I wanted.
