* How does the land in an area affect the water in that area?
* How are watersheds characterized and defined?
Materials needed for this investigation
~ A sheet of paper (computer paper, notebook paper, etc. Wax paper or other “water resistant” paper will also work.
~ A water-soluble or washable marker (like Crayola, not a Sharpe or Expo).
~ Water (ideally in a spray bottle, but you can also flick water from your hand or a scrub brush if you don’t have an empty spray bottle).
~ Notebook paper to write on or another way to share your learning with your peers and/or back to your teacher.
Build a model of a watershed:
- Lightly crumple your blank paper and open it up so there are peaks and valleys and it fits loosely in your hand.
- Mark the peaks and ridges with your water-soluble marker. If this color were to run off, where would it go? Make a dot on your model where you think the color will collect. If you have more than 1 color, you can try to identify multiple watersheds in your model.
- Spray your model (over a sink or outside) to represent precipitation.
- Make observations as the marker runs down your model. Write down what you notice and wonder about what is happening in your model.
Watch the video.
After reviewing the map above and the information from the video:
Using the information you have gained, answer the inquiry questions. Using as many of the following words as you can in your explanation: watershed, watershed boundary, basin, sea, river, downhill, flow, precipitation, ecosystem
