  • Could try to cut the jello into 20 pieces, one for each child. If it’s not enough, cut 10 and split children into girl/girl, boy/boy pairs. Then have boys try uplifting and girls try overthrust. Save one piece for teacher to try erosion with a blow dryer.
  • Transcript

    • 1. Edible Geology -directions
    • 2. Limestone
      • First layer is limestone
      • Formed when land was under water
    • 3. Sandstone
      • Formed by sand deposited by a river
      • AGENT EROSION
      • Fossils are often found here
    • 4. COAL
      • Formed when area was part of a large swamp
      • Very important to fossil hunters
      • Where you find coal, you are likely to find fossils nearby
      • Dark coal beds are easy to spot
    • 5. COAL
    • 6. Sandstone - 2
    • 7. Siltstone
      • Made of grains that are smaller than sand, but larger than clay
    • 8. Final Formation
      • Which layer is the “oldest”?
      • Where are the fossils?
      • Will they ever be found?
      • Rock layers can stretch, bend, and even break
    • 9. Uplifting
      • Pressures inside the earth form mountain ranges
      • Can twist rock layers
      • Slide a knife under the center of your gelatin square and lift.
      • Bend…and break
    • 10. Overthrust
      • Rock layers (strata) can get mixed up another way
      • Gently push in from opposite sides of the square so the center rises up.
      • Mixed up strata
      • makes it hard to
      • determine where
      • youngest strata is
    • 11. Faulting
      • Earth’s surface has big cracks called faults
      • Sometimes land around a fault line is raised above another
      • Don’t waste your
      • jello…just look here:
    • 12. Finally…Erosion
      • Rocks are constantly being worn away by wind and rain, uncovering fossils
      • Ahhhh!
