Procedure1. Determine which of the objects should represent each
planet – keeping in mind size comparison for each planet.2. Record your choices on your data table.

Procedure1. Decide how far apart the objects would be if
they really represented the scaled objects in the solar system.
2. Measure distances (cm) from the Sun to each planet.
3. Record your data in the data table.
4. Explain your reasoning.
5. Be prepared to present and defend your decisions to the class.

Discuss your thinking…• What influenced your decisions about planet
sizes and order?• What influenced your decisions about
distance?

DISTANCE NOT TO SCALE!!!!!

How’d you do size-wise?• If you had the first 4 as smaller objects
(Mercury as the smallest) and the second 4 as larger objects (Jupiter as the largest) you were on track.
• This is typical because we see planets to scale on posters, in books and in diagrams.
• Here are a few to scale models that compare the planets (and some stars) side by side.

How’d you do distance-wise?• Thoughts or questions from the
Solar System walk?• Why were you so far off with your
model?• 1 AU = the average distance from
the Earth to the Sun. (A little less than 1,500,000 km)
