Geologic Time Scale Foldable Project
Directions
1.
Create 14 flaps by folding 7 pieces of staggered copy paper. Stagger the pieces by
approximately 1/2-3/4 inch. Staple twice at the top to hold papers in place.
2.
Write the title: Geologic Time Scale on the top flap. Underneath write the definition of the
geologic time scale.
3.
On the left-hand bottom portion of flap of flap#2, write: Early Earth. On the top of this flap,
write a description of Early Earth in your own words. Use pg. 288 as a resource.
4.
Label the flaps on the left-hand bottom portion of flap with the period and relevant time
period. See #4. Use the same color to label PERIODS within the same ERA.
5.
Label the right hand side of the flap (in vertical writing) with the ERA. Be sure to use the colorcoding you used in #4. See #5.
6.
On the right hand side of the flap, write a description of this time period. Use your textbook
pages 292-293. See #6. Use the back of the flap if you need more room!
7.
On the left hand side of the flap, include and illustration or piece of clip art of an example
organism. Be sure to use COLOR and to label your picture with the organism’s name! See #7.
Include an illustration of 1
organism that lived during this
time period. Don’t forget to
include the name!
DESCRIPTION
Invertebrate sea
organisms evolve
(organisms without a
backbone). The seas are
filled with sponges, snails,
clams, and worms.
PALEOZOIC
EXAMPLE ORGANISM: Pikaia
7
Include a description
of the major events
that occurred during
this time. Use pgs.
292-293 as a resource.
Cambrian: 544-505 mya
4
Include the period
and relevant years
in the bottom left
corner of flap.
Label the ERA on the
right side edge of the
flap. Color code these
so that flaps that
belong to the same
era have the same
color label.
