I can model and describe a watershed. 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… I can model a functioning watershed and write a post-lab conclusion.

Today’s lab – Modeling a watershed

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

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

Where does our water come from?

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.

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

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)

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
