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.

Learners combine different plant solutions -- made from fruits, vegetables, and flowers -- with equal amounts of vinegar (acid), water (neutral), and ammonia (base).

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

This is an activity to do when there is a solar eclipse!

In this craft activity, learners create a string of cut-out moons and stars.

In this activity, learners will see how UV light affects colors over time by making their own sunprint on construction paper.

In this activity, learners observe mixtures of sand samples glued to note cards, and consider how sand can differ in size, shape, and color, and where it comes from.

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.

Learners use a candle to investigate the products of combustion. When a glass rod is held over a lit candle, the candle flame deposits carbon on the rod.

In this activity, learners construct a home-made journal with simple, everyday materials.

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.

The Sacred Cenote at Chichén Itzá is a sink hole, or well, containing groundwater. In this activity, learners create their own cenote using chalk, limestone, acids, and rain water.

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.

In this activity, learners will design a seed and test how it travels. Learners will use the Engineering Design Process to create a seed which can move from place to place.

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.

In this quick activity, learners practice locating a constellation in a map of very dark skies.
