Scaling Down the Universe

FOURTH LESSON, THE UNIVERSE:
This lesson project will have the class making 1 inch representations of groups of galaxies, at least 25 of them. The scale will be 3 centimeters equals 2.2 million light years (I suggest this scale because it relates to the size of the last installation). Assuming the universe to be presently 15 billion light years across, the outside limit of this scaled down universe will be approximately 200 meters. This will obviously not be able to hang indoors; and considering the billions of galaxies in the universe, we will have to make do with representing many small versions of local groups of galaxies and imagine the rest to a distance of 200 meters.
