Learners take on the role of environmental engineers as they design water filters.

In this activity, learners simulate nature's water filtration system by devising a system that will filter out both visible and invisible pollutants from water.

In this engineering activity, challenge learners to invent a water filter that cleans dirty water.

In this activity, learners explore how engineering has developed various means to remove impurities from water.

In this activity, learners receive a labeled plastic film canister containing a material representing a pollutant (i.e. pencil shavings = a beaver's wood chips).

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 this activity, learners explore how engineers work to solve the challenges of a society, such as delivering safe drinking water.
