Introduction: Ask the students how large they think the Solar System would be if we reduced the size six trillion times? Discuss.
In order to build the Solar System to this scale it will fit in a meter if we include Pluto. In this model, Pluto would be about one meter from the sun.
Students will work in groups of 2 or individually.

Have students make labels for all planets and Pluto in Braille (for braille students ) using the APH small label paper. Print students will write the planets directly on the paper.

After labels are prepared, reminding the students that this meter represents the entire Solar System, have the students fold the paper in half. Ask the students which planet they think will be at this fold? Discuss.

Students will likely be surprised to find out that Uranus is the planet to place at the halfway mark. Discuss Explain that the distances increase as you go further from the Sun. Discuss.

Fold the half of the paper past Uranus in half. Ask  What planet will go at this point?  Neptune.

Label the far end of the paper Pluto

Fold the other end of the paper in half  This is where the Saturn label should be placed. Discuss the decreased distances between planets as we head toward the Sun.

Fold in half again and label Jupiter.

Fold remaining paper in half twice and then label Mars.

Ask  Why are these distances SO much smaller.

Fold again and label Venus

Fit Earth between Venus and Mars

Fold one last time and label Mercury  This will be essentially at the beginning of the paper.

After completion of the model, discuss the relative distances. Were students surprised? Proceed with instruction as planned.
Helpful information as you complete this activity for the instructor: (This information will not be given to the students.)
Distance from Sun in this model (measurements are in standard units):

Pluto  39 1/2 "

Uranus  19.25 "

Saturn  9.60"

Jupiter  5.25"

Mars  1.5 "

Earth  1 "

Venus  3/4 "

Mercury  3/8 "
