Last time in garden class, we learned about the water cycle - it describes how water moves around from land to air and back again! Over and over!
*A watershed is like a giant funnel - it collects water and describes the journey of water on the land.
*The San Francisco Bay Area is a giant watershed!
*Water flows down from the hills, from the Sacramento and San Joaquin Rivers, into the Delta, into the Bay, and eventually out into the Pacific Ocean!
Berkeley is part of the watershed!
*We want water to soak into the ground - it helps our garden and all the plants and animals who live here.
What would happen if water couldn't soak into the ground? (think about parking lots and roads)
What would happen if the water became polluted along its trip through the watershed?
Activity - Make a 3D watershed topographic map
1. Crumple up a piece of paper and gently unfold it
2. Notice the "hills" and "valleys"
3. Color your watershed with green hills, brown soil, and blue water.
4. Observe: where would water collect and flow?
Bonus Thought: What would happen if pollution got into the watershed at the top of a hill?
