Stratigraphy—the study of the origin, composition, distribution, and succession of different layers of rock and earth—is fun to talk about because it is like reading a book of the past. The deeper you go, the older the rock and fossils get. In this activity you can do at home, Lead Preparator Taylor uses a Mason jar to help illustrate the different layers of rock she discovers while digging for dinosaur fossils!
Materials:
Keep in mind you can substitute any layer with something else you have on hand!
- Mason jar with a lid
- Sugar
- Some noodles
- Toy dinosaur(s)
- Flour
- Coffee grounds
- Some sand with pebbles
- Mulch
- Large quantity of a sandy substance of your choice. This will be the fossil layers so make sure you have at least 2 cups worth of this material
