Scale-model capstone — Homework

Use the ratios: divide by about 110 for Earth's size, multiply by about 107 for the Earth-Sun distance.

  1. 1.A beach ball 40 cm across represents the Sun. About how big should the modeled Earth be?
  2. 2.Using that same 40 cm beach ball Sun, about how far away should Earth be placed?
  3. 3.Why must you use the same scale factor for both the size of Earth and the Earth-Sun distance in your model?
  4. 4.If you doubled the size of the object representing the Sun, what would happen to the modeled Earth-Sun distance?
  5. 5.Describe your planned scale model: what object represents the Sun, what its calculated Earth size and distance are, and where you would set it up.
