Today, Bobby and I managed to print out images of each planet in the Solar System, in addition to the Sun and Pluto. As we identified the images we wanted to save of each planet, we discussed their characteristics. We printed two sets of copies: one is for Bobby to take home, and the other set we taped to the wall in Bobby's room in numerical order from the Sun. Next step: Look at the relative scale, by setting the distance from the Earth to the Sun in the 'model' Solar System to equal, say, one yard.
