In this activity, learners experiment and observe how the color of materials that cover the Earth affects the amounts of sunlight our planet absorbs.

Millions of organisms can live in and around a body of water.

Professor John Endler traveled to Trinidad in the 1970s to study wild guppies. In this activity, learners take part in an online simulation of Endler's work.

In this activity, learners play an evolution card game to see how selective pressures can affect an organism's evolution.

In this activity, learners will test soil content using their sample, some water and a container that seals.

In this matching game, learners study the limits of life on Earth to see what other places in the solar system might sustain microbial life.

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

Learners compare the properties and solubilities of Styrofoam (TM), ecofoam packing peanuts, and popcorn. First, the solubility of each substance is tested in water.

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

In this activity, learners gain knowledge about how carbon moves through all four of the Earth’s major spheres (biosphere, hydrosphere, atmosphere, and lithosphere), and understand how humans influenc

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

In this activity, learners are introduced to tree rings by examining a cross section of a tree, also known as a “tree cookie.” They discover how tree age can be determined by studying the rings and ho

In this activity, learners will build a honeycomb. Learners will investigate how the shape of the honeycomb develops. Activity includes step-by-step instructions and extension ideas.

In this activity, learners will create a home for animal friends in their backyard using recycled materials. Some material suggestions include: pine straw and twigs.

In this group activity, learners consider environmental conditions—temperature, presence of water, atmosphere, sunlight, and chemical composition—on planets and moons in our solar system to determine

To convey the concept of how animals adapt to survive, this game asks learners to imagine what adaptations a given animal would need to live in a certain environment—including environments where such

In this activity, learners will use their five senses to explore a nature-based area around them.

In this activity, learners will experiment to find how long it takes to compost paper. They will create their own compost container and test different variables.

In this game, learners try to find nano-related objects on a game board. Learners investigate the different ways nano is in the world around us.

This game introduces learners to the scale of the greenhouse gas problem, plus technologies that already exist to dramatically reduce our carbon emissions and prevent climate change.
