DISCUSS:

So far, Doug has found fossil seashells and a fossil shark tooth. What other fossils do you think Doug would find in the quarry?

Step
01/16
Find a partner.
Step
02/16
Get these supplies. You’ll get more later.
Step
03/16
Write your name on this Fossil Dig sheet. Cut along the 2 dotted lines
until you reach the stop signs.
Step
04/16
Put the page with your name in it on top of the other page. Then fold
stickers over both pages near the arrows.
Step
05/16
Open the top layer, Layer A, of your fossil dig. Examine the fossils
that you find in this layer.
Step
06/16
Look at the traits of each fossil. Then fill in question #1 on your
worksheet and discuss with your partner.
Step
07/16
Discuss. Then fill in question #2 on your worksheet.
Step
08/16
Open Layer B of your fossil dig. Examine the fossils that you find in
this layer.
Step
09/16
Fill in question #3 on your worksheet and discuss with your partner.
Step
10/16
Discuss. Then fill in question #4 on your worksheet.
Step
11/16
Get the rest of your supplies.
Step
12/16
Cut out your Mystery Fossils.
Step
13/16
Observe the traits of your Mystery Fossils. Sort them into two piles.
It’s ok if it’s hard to tell where some belong.
Step
14/16
Place them into their fossil layer. Then glue them in.
Step
15/16
Discuss these questions.
Step
16/16
Discuss these questions. Then watch the next video.

DISCUSS:

Do you think habitats have changed in other parts of the world besides Illinois? How could you find out?

THIS LESSON WAS REVISED ON JULY 1, 2019. Here is a link to the previous version.
In this lesson, students explore the idea that the rock under our feet sometimes contains fossils, and investigate how these fossils reveal changes in habitat through time. In the activity, Fossil Dig, students use paper to create a model fossil dig. They identify traits of fossils to determine what the habitat looked like when these organisms were alive. Then they use this information to figure out where some Mystery Fossils belong in their fossil dig.
