Bobby and I started working on a scaled-down model of our Solar System. I began class by asking Bobby if he works with models of anything, and he eagerly told me about his car collection. I explained the concept of 'scale' to him, and how all dimensions of the original need to be scaled down by the same proportion, otherwise the model will be nothing like the original. We then proceeded to start collecting online images of the Sun, Mercury, Venus, Earth, and Mars (but were unable to print them today) that will be used when we assemble our model that will illustrate the relative distances between the planets.
