Geology Building Worksheet

We are visiting the geology building at the University of Utah to learn about fossils today. We will learn the types of fossils, identify them, and see research laboratories and a college campus.


Station 1: Fossil not a Fossil
1. Is a footprint a fossil? (circle one) yes  no
Why? ________________________________________________________________


2. Which of these is not a fossil?
a. A dinosaur bone
b. Poop that turned into rock (coprolite)
c. A worm burrow
d. A footprint
e. An imprint of a leaf
f. They are all fossils


3. Could you extract dinosaur DNA from a bone? (circle one) yes no
Why? _______________________________________________________________________

Fossil identification activity
In front of you are different materials. Can you identify at least four samples that you think are fossils?

Sample What type of fossil do you think this is? What organism do you think created this?

Create a 2D “cast” fossil activity. Use a crayon or pencil to create a rubbing of a flat fossil.

 

 

Station 2: Fossils Building Tour Observations vs. Inferences 

An observation is based upon something you can sense or measure.
An inference is a conclusion based upon comparing observations with previous knowledge.
