  1. Planetary Size and Distance Lab #3

  2. Classroom Model • The moon is approximately miles from Earth. • Approximately 1/3 the sun’s diameter • the Earth’s circumference is ~ 25, 000 miles 238, 857

  3. Classroom Model • If Earth were the size of a globe, the moon would be the size of a tennis ball.

  4. Classroom Model • If Earth were the size of a globe, the moon would be ~9 meters away.

  5. Outdoor Model • The sun will be the size of a hula hoop: 1 mm = 1000miles OR 1m = 1Mmiles (million miles) 1:1,000,000 ratio Diameter Distance

  6. Outdoor Model DIAMETER: (1 mm = 1,000 miles) Planet Y has a diameter of 10, 000 miles MOVE DECIMAL 3 Places!! 10,000 miles = 10 mm

  7. Outdoor Model DISTANCE: (1 m = 1 Mmiles) Planet X is 8 Mmiles away Just change the units!! 8 M miles = 8 m

  8. Outdoor Model Comparable Object: Think of something that is the size of each planet in the new scale. For example something that is 20 mm in the scale would be the size of a quarter.
