1. Weathering & Erosion Lab
Comparing & Contrasting Different Earth Samples

2. Essential Question:
What happens to the Earth when wind, burrows, buildings, and rain weather Erode it?

3. Step One-Observe 4 Earth Samples
What type of Earth would you build on?
Grass Lands
Sand
Dirt
Rooted Earth

4. Step 2-Wind Erosion Can you see the effects of weathering/erosion?
Which of 4 types of soil was affected most by the wind?

5. Step 3-Effects of burrowing animals/digging holes
Does this effect weathering and erosion of the Earth?
Observer the results
We will use a skewer to create holes to simulate burrowing

6. What did you notice?
Hopefully, that roots created a barrier, around the soil.

7. Now we will attempt to simulate the effects of acid rain
Are you still thinking about where you would like to build?

8. Step 4-Acid Rain
We will drop one full eye dropper on each mold. (Observe the results)

9. Which plot has the most stability for your home?
Are you noticing the effects building can have on earth?
Now we are going to add a light shower by using a spray bottle.
What do you notice?

10. Step 5-Simulate Dust Storm
We will use a hair dryer to demonstrate the effects the wind would have had on the loose soil during Dust Bowl.

11. Erosion
Process by which surface of the earth is worn away by action of water, glaciers, wind, and waves.

12. Weathering
Chemical process that causes exposed rock to decompose
