Scaling Down the Universe
Your feedback is important to us!
After viewing our curriculum units, please take a few minutes to help us understand how the units, which were created by public school teachers, may be useful to others.
The next phase can be accomplished by the teacher or one of the more coordinated students. Using the needle nose pliers, more wire and whatever else is necessary, start attaching all the various clusters together so that you have a large supercluster of galaxies approximately 15-20 centimeters across. Save two of the local clusters aside for later. When it is done, have the class estimate the scale size of the supercluster if one local cluster equals the distance to our own Andromeda Galaxy of 2.2 million light years.
