Lava Flow Challenge

In the Lava Flow Challenge your group is tasked with the job of helping a town near an active volcano develop a system for determining if and when they should evacuate during a volcanic eruption.
Your job is to
  • design a method for measuring the rate at which lava flows.
  • use dish soap to simulate lava

What is Weathering?


What is Erosion?
  • the movement of soil or other materials from one place to another

Erosion Walk

  • With your group, walk around outside and identify at least four different examples of erosion. Describe the erosion and explain what you think might have caused the erosion

Erosion Case Studies

  • You will read several Case Studies about Erosion. Use the Erosion Case Study sheet to record information about each of the case studies.
  1. Read the case study (or case studies) your teacher assigns you.
  2. For each case study you are assigned, identify what happened and why. Describe the case you are reading about well enough so others can learn from what you write.
  3. Make a list of the causes of erosion that you have read about.
  4. Identify an example of erosion you saw on your erosion walk that is similar to the erosion you read about. Use the case you read about to give you ideas about what caused the erosion you observed.


Investigating Factors that Affect Erosion

We will complete two investigations to find out more about erosion. You will need a place to record your data. Use the following links to see a sample of the data table.
