Can you Prevent Erosion?
Objective
Using the Stream Table and available resources you will attempt to prevent erosion.
Brainstorm - Discuss with your group things that you think might prevent erosion. Turn your best idea into a question that can be answered by conducting an experiment.
example: To what extent would ___________ prevent erosion from happening?
Make a hypothesis.
I think _________ will prevent erosion because _________.
Develop a materials list and set of procedures.
Conduct your experiment.
Collect data and make a conclusion that attempts to answer your original question.
Brainstorm
Meet with your team to develop a plan for preventing erosion.
Consider the resources that are available to you.
Create a written plan with diagrams that you will use to implement your plan.
Your plan should...
have a clearly stated objective.
include all materials.
include diagrams to identify all associated parts.
include a step by step list of instructions for implementation.
Whole class...
Meet with other teams to describe your plan.
Listen to other plans and ask questions for clarification:
Why did you choose...?
How are you going to...?
When are you...?
Provide feedback.
Back to teams...
Consider what you have learned by viewing other plans.
Modify your plan based on the questions and feedback you received from the other teams.
