In this activity, learners simulate nature's water filtration system by devising a system that will filter out both visible and invisible pollutants from water.

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

In this activity, learners explore how engineering has developed various means to remove impurities from water.

In this activity, learners use objects they find on a nature and water to make creative frozen sculptures.

An estuary is a body of water that is created when freshwater from rivers and streams flows into the saltwater of an ocean.

Glare from the sun and ripples from the wind can make it hard to see what's below the surface of a body of water.

In this activity, learners use tonic water to detect ultraviolet (UV) light from the Sun and explore the concept of fluorescence.

April showers bring May flowers, but what do coastal storms bring?

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.

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

Learners create a model of a wetland to observe how it absorbs and filters water from the environment.

Build a hydrometer (measures the density of a liquid) using a pipet or eyedropper.

Learners follow directions to construct a water-powered electrical generator using a turbine made from plastic spoons.

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

Ocean acidification is a problem that humans will have to deal with as we release more and more carbon dioxide into the atmosphere.

In this activity, learners examine photo images of Earth taken from space, and attempt to identify and explain some of our planet's geological features.

In this physics activity, learners build their own rockets out of film canisters and construction paper.

In this activity, learners will make their own prism and use a glass of water to separate sunlight into different colors.

In the wild, small crustaceans known as brine shrimp live in marine habitats such as saltwater lakes.

In this data collection activity about crabs, learners use data from the Virginia Institute of Marine Science (VIMS) trawl survey to determine the areas of the Chesapeake Bay that are being used by bl
