Central Elementary kids! You have been learning about healthy watersheds. Remember:
A pervious surface allows rain water to soak into the soil. Pros: waters the plants, refills the ground water supply, reduces toxic runoff into streams and ocean. Farms, yards, and natural areas are pervious surfaces.
An impervious surface does not allow water to soak into the soil. Cons: water does not penetrate the soil to water plants and refill groundwater. Toxic chemicals quickly runoff into streams and the ocean. Paved roads, parking lots, and rooftops are examples of impervious surfaces.
Nice job with your drawings. We posted a few here and in the Student Gallery!
