Low-Tech Water Filter for High-Impact Clean

In this activity, learners consider the water features they might enjoy at a community park--a pond, brook, water playground (or "sprayground"), or pool--and what happens to the water over time. In small groups, they explore and test common materials to identify the best low-tech materials that can be used to help filter water. This activity is part of a curriculum designed to engage learners in hands-on engineering challenges....
