1. Place several sheets of newspaper or wax paper over a large flat surface, such as a kitchen counter. Use at least five sheets of paper so that you can protect your work area. 2. Crumple the sheet of white paper into a loose wad.
3. Uncrumple the sheet of paper so you can lay it on your work surface. The paper should not be flat but should be wrinkled and puffed up from the crumpling.
4. Imagine the paper as a miniaturized version of mountains, hills, valleys, and other landscape features. If your paper is so flat that you can't imagine these features, you should recrumple it.
5. Use the marker to color the major folds or ridges in the paper, as well as some of the minor folds or ridges. 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 probably do the job.
7. Stop misting as soon as you see some of the colored water starting to collect in some of the valleys. Watch for a few moments as stream patterns develop over the paper.
8. If you have access to a digital camera, take a photograph of your work and include it in your Data and Observations.
9. Record your observations of each watershed that forms in Table 1. Take note of headwaters, channels, divides, tributaries, mouths, floodplains, precipitation, and infiltration in your descriptions.
10. Complete the Questions and Conclusion section of the lab report.
