Learning target
I can model and describe a watershed.
Today I am…
Modeling how a watershed functions.
So that I’ll be able to…
understand how runoff impacts our water quality.
I’ll know I’ve got it when…

4. Today’s lab – Modeling a watershed

5. What we already know…. The Water Cycle summarizes the
role that water plays
in our environment.

6. Background Information
What is a watershed?
A watershed is all of the land that drains runoff (from precipitation) into a body of water.

A watershed carries water "shed" from the land after rain falls and snow melts.

8. Where does our water come from?

9. Modeling a watershed
You will work with one table partner to create a model of a watershed. Each person is required to submit a lab worksheet.
We will walk through a few steps together and then you will guide yourselves.

10. Answer pre-lab questions (1-3) Make your hypothesis

11. Set up experiment 1. Crumple the paper (medium) 2
Set up experiment 1. Crumple the paper (medium) 2. Draw lines from the high points the low points (at least 5)

12. We will spray our paper 5 times total. Each spray represents 1 day
We will spray our paper 5 times total. Each spray represents 1 day. Goal: You and your partner should get to #11
