Gizmo of the Week: Water Pollution

April 14th marks the 50th anniversary of the death of Rachel Carson, a researcher and writer who started the environmental movement in 1962 with the publication of “Silent Spring.” Carson first became concerned with widespread pesticide use while working for the Fish and Wildlife Service in the 1940s.

Water polution“Silent Spring,” which documented the devastating effects of DDT on wildlife, brought environmental issues to the forefront and led to a ban on DDT use.

The Water Pollution Gizmo presents a variety of types of water pollution, including toxic, sediment, nutrient, and bacterial. Students learn about each form of pollution and identify the kinds of pollution that apply to a variety of real-world scenarios.

As an extension to the lesson, have students create public service announcements on how to reduce water pollution in their communities. This makes a great Earth Day activity!
