How big is it?
Prepare your students for scale modeling.
Draw a circle on the chalkboard or on paper. It should be 8 inches in diameter. This represents the Sun. Now have your students draw circles according to what they think the sizes of the planets would be.
Mercury - .028 in
Venus - .070 in
Earth - .073 in (about the size of a piece of pepper)
Mars- .039 in
Jupiter -.80 in (a little bigger than a penny)
Saturn - .67 in
Uranus- .269 in
Neptune- .261 in
