Science Experiment: Making Mountains

Making Mountains

What is Geology? The study of the Earth

What part of Earth do people live on? The crust.

What are the layers of the Earth? What are they made of? Solid or liquid? Inner core is solid. Outer core is liquid. Mantle is like silly putty. We have learned what the layers are by monitoring earthquakes. They produce an S-Wave that can not travel through liquids. It leaves a shadow behind when we try to hear the wave from the other side of the world.

What are some things we know about the earth’s crust since we live here? Has it always looked the same?

In sedimentary rock, there are layers of sediment and often fossils form in this sedimentary rock from the burying of animals or plants. Are the older layers on the top or the bottom? Bottom (Dirty laundry Example) This is the law of superposition which helps scientists date fossils because the deeper we dig, the further back in time we see.

You will need: Dough of different colors, Shells

  1. Roll the first dough into a flat pancake. Sprinkle with shells(fossils). 
  2. Repeat this for another layer. (dough/shell/dough/shell/dough/dough/dough) 
  3. Push the sides together to make an arch.
  4. This happens when rocks are squeezed together. 
  5. Adult will use a butter knife to slice off the top at an angle to reveal the layers.
