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

In this activity, learners design a flag for a chosen or assigned planet. The instructions include information about flags on Earth, and a list of flag references.

In this activity, learners explore how musical instruments are engineered.

In this environmental activity (page 16 of the PDF), learners will calculate the amount of energy they save by recycling paper, plastic, glass, and aluminum materials over the span of a week.

In this online game, learners must purchase power plants for their city.

This is an online game about the complexities of farming. Learners will "draw" cards and make decisions about how to take care of their farm.

In this activity, learners use a model for how fishing affects marine life populations, and will construct explanations for one of the reasons why fish populations are declining.

In this activity, learners visualize the differences in water density and relate this to the potential consequences of increased glacial melting.

In this activity, learners conduct a waste audit and use their findings to implement a plan for reducing trash.

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, a group of learners work collaboratively to design and construct a paper model showing the evolution of an environment through multiple stages, from prehistory through the modern cit

In this activity, learners listen to a story about a made-up endangered species--a flying frog! Learners print out six story pages and then draw the pictures and write the captions.

In this lesson, learners will understand the concepts behind endangered and extinct animals and develop their own conservation plan to save three endangered species.

In this thought-provoking activity, learners plan a hypothetical project to build and operate wind turbines in their community.

Working in groups, learners model the continuous destruction and creation of ozone (O3) molecules, which occur in the ozone layer.

While playing a game, learners discover how the Endangered Species Act works in the United States. Learners move along a game board by answering questions correctly.

In this outdoor activity, learners plan a simple foot path and create an environmental impact study of the natural area where the path would be.

In this activity, learners explore in what ways the shape of the land and the pull of gravity influence how water moves over Earth.

In this activity, learners practice the steps involved in a scientific investigation while learning why ice formations on land (not those on water) will cause a rise in sea level upon melting.

In this activity, learners investigate the food, water, and space needs of common livestock animals.
