Assignment: “ Construct” Scale Model of the Solar System Sun is a basketball. Place basketball in front of Mike the Tiger’s habitat. Walk to Earth’s distance, turn around and take a picture of the basketball (sun). Walk to Jupiter’s distance, take picture of sun. Walk to Neptune’s distance, take picture of sun. Assemble all images, along with explanations, into a PDF document. How far away is our nearest neighbor basketball? Due via e-mail (tohline@lsu.edu): By 11:30 am, 25 January (Friday)tohline@lsu.edu You may work in a group containing no more than 5 individuals, all of whom must be students in this class.
