Learners build a filter from old soda bottles and dirt. They create polluted water, and pour it through their filter to clean it.

In this multi-part activity learners examine non-point water pollution.

In this environmental science lesson, learners will examine the dangers of mercury and how humans contribute to growing mercury emissions on Earth.

In this activity, learners investigate various appliances and electronics, discovering how much energy each uses and how much carbon dioxide (CO2) is released to produce that energy.

This is a comprehensive lesson plan on page 85 for a group cleanup trip to a local beach, lake or stream. Learners keep track of the types and amounts of trash picked up and analyze this information.

Many people get water from a source deep underground, called groundwater.

In this environmental science lesson, learners will examine hazardous chemicals and their effects on human health and the environment.

In this activity, learners make a model of a pollution spill that occurred at Bangs Lake in Mississippi and measure water quality parameters in their model.

Water treatment on a large scale enables the supply of clean drinking water to communities.

When it rains, water can collect on top of and seep into the ground. Water can also run downhill, carrying soil and pollution with it.

In this field study, learners discover how to collect data in the field and how their efforts can help certain animals, specifically, amphibians.

Where rainwater goes after the rain stops? And why there are rivers and lakes in some parts of the land but not in others?

In this activity, learners explore how environmental engineers might approach solving the problem of an oil spill.

Learners add acid rain (nitric acid) to two cups that represent lakes. One cup contains limestone gravel and the other contains granite gravel.

In this game, learners match descriptions of marine debris (shoes, batteries, paper towels, etc.) to images of these items.

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 environmental science and data analysis activity, learners work in groups to track a Dead Zone (decreased dissolved oxygen content of a body of water) using water quality data from the Nutrien

In this data analysis and environmental science activity, learners examine the effects of pollution on amphipods using data from the Chesapeake Ecotox Research Program.

In this activity, learners explore a bucket of sand and beach objects.

In this activity, learners explore clouds and how they form.
