Water pollution is everywhere, and pollutants range from oil to fertilizers. Bring the concept to life by demonstrating the difficulties in getting particular pollutants out of water.

Ecology candidates culture pond water organisms over a few days time, then they experiment to find out how increasing nutrients affects the population. As part of a unit on water, this exploration gives your class an understanding of how...

Having a clean, reliable source of drinking water is essential for any community, but in many cases this is easier said than done. Engage young environmentalists in exploring the five factors affecting vulnerability of a groundwater...

[Free Registration/Login Required] Students read about how varying amounts of fresh water can affect biodiversity in a region. A question sheet is available to help students build skills in reading comprehension.

In a bioassay, a living organism serves as a detector for toxins-the same way canaries were used in coal mines to detect invisible toxic gases. In this project, water fleas (Daphnia magna), a freshwater crustacean, are used in a bioassay...

By looking at the bottom dwelling macroinvertebrates, students will investigate water quality and habitat quality in this field lab. Students will record the number of creatures found at the bottom of a pond, lake, ditch, stream or river...

Engineers work in many fields associated with precipitation. Engineers study glaciers to better understand their dates of formation and current demise. They deal with issues of pollution transport and water yield, and they monitor...

Read how freshwater moving across the surface of the Earth can become polluted and bad for the environment. Create a model that shows how water can become polluted as it flows downhill.

In this scenario-based activity, students design ways to either clean a water source or find a new water source, depending on given hypothetical family scenarios. They act as engineers to draw and write about what they could do to...
