Grade 6
Science
Unit: 09 Lesson: 01
Making a Model of the Earth
Materials:
sheet of plain paper
colored pencils
ruler
pencil
scissors
Directions:
1. Fold the sheet of paper in half vertically (lengthwise).
2. With the folded edge to the left, cut through both thicknesses from the point
of the fold to the top right of the page. This will create a folded
Side with fold
triangle.
Cut
Discard this
section.
3. Leaving the triangle folded and with the point facing down,
use the following measurements to make marks on the folded edge.
4. Measure, mark, and draw a line for the following, and color as indicated below. Start measuring
from the bottom, narrow point of the triangle, and then take the next measurement beginning
from the previous line. Remember, the layers are not to scale.
4.5 cm – red
6 cm – orange
28 cm
8 cm – yellow
8 cm – brown
1.5 cm – green
5. Open the triangle, and leave the narrow point at the bottom. Using the measured marks as a
guide, sketch a slight arc for each measurement on the triangle. You can make the arcs with the
colors above.
6. Refold the triangle with the folded side on the left. Label each section with the name of a layer,
beginning at the narrow point of the triangle:
inner core
outer core
lower mantle
upper mantle
crust

7. Unfold the triangle, and cut along each line from the right hand side of the triangle only to the
center fold. This will create a flap for each section.
8. Open all sections, except for the one at the point. Leave that flap closed. Draw a line along the top
edge of the flap, so that it leaves a line on the inside page. Continue to close the flaps and draw
the lines.
9. Open all flaps, and extend the line across the page for each flap.
10. On the inside of each flap, you will research and record the following information for each layer of
your model:
name of the layer
thickness and/or depth
composition (elements it is made of)
temperature (both °C and relative, as compared to differing layers)
interesting facts (such as rocky, solid, liquid, semi-solid, etc.)
11. You will need to write small to be able to fit the information on the flaps for the inner core and
crust.
