In past lessons, we have touched upon the scale of things - and how important it is for an accurate representation of the real world that when we miniaturize or enlarge something that it is done to scale. Maps are a good example. With our Solar System, the relative sizes and distances are often misrepresented in books. So Bobby and I prepared a model of the Solar System to illustrate the relative distances of the planets by taping pictures of the Sun and the planets to the walls of the corridor at the school and placing them at the calculated distances, using the distance from the Earth to the Sun as 1 foot.
