Lab: Solar System to Scale
DIRECTIONS SHEET
PURPOSE: The lab activity will illustrate the relative sizes of the planets, and give the students practice
with the concept of scale.
MATERIALS: Construction paper, scissors, glue stick, compass, ruler, pencil, directions sheet.

A. Scale Sizes
1. For small planets, draw a line on construction paper for the scale length of the diameter. Then neatly
draw a circle around the line. Very carefully cut out the planet. Don’t lose it!
2. For larger planets, use the compasses to draw a circle on the construction paper using the planet’s
scale radius.
Here is how Jupiter is done:
Draw Jupiter on the paper, cut it out, and
write its name on the cut out piece.
3. Finish drawing, labeling, and cutting out the rest of the planets.
4. Arrange the planet cutouts so that they ALL fit on one piece of construction paper.
Then glue them all down. Use a glue stick.

B. Scale Distances
1. Draw a 25 cm line across the map of this area starting from the base of the flag at
Pickens Middle (Junior High).
2. Starting from PMS, use the scale to show where each of the planets would be located.
Label their locations.
3. Tape or glue the map to the bottom of the scale size paper, part A.
Answer these questions on the BACK OF YOUR CONSTRUCTION PAPER.
Put the number and the answer only on your paper.
1. Which planet was the smallest?
2. Which planet was the largest?
3. How many Earths would it take to equal the diameter of Jupiter?
4. How many Plutos would it take to equal the diameter of Earth?
5. How many Plutos would it take to equal the diameter of Jupiter?
6. How many times larger is Saturn compared to Earth?
7. Which 2 sets of planets are almost the same sizes?
