TITLE: Wad a Watershed Lab
INTRODUCTION: Using models is very important in science. In this lab, you will design a model that will help you investigate the relationship between land surfaces and water on Earth. OBJECTIVE: To design a model that will help you visualize watershed characteristics. PROBLEM: How can we use the relationships between land surfaces and water to understand conservation of resources and pollution? HYPOTHESIS: In your own words, write a hypothesis about how the relationships between land surfaces and water influence pollution and the conservation of resources.” Make a prediction about how the relationship between land and water can influence pollution and the conservation of resources.

Use the marker to color the major folds or ridges in the paper, as well as some of the minor folds or ridges, as shown below. Do not allow the marker to color any other part of the paper. 6. Place the paper on top of the newspaper on the counter, and then lightly mist the piece of paper with the spray bottle. Don't spray too heavily: Three to seven squirts will...
