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.

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

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

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

In this activity (12th on the page), learners investigate their ability to discriminate (see) different colors.

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.

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 physics activity, learners will explore buoyancy.

In this chemistry demonstration, learners will discover that phenolphthalein is an acid/base indicator. One learner will read a poem about four witches making a potion.

In this design challenge activity, learners design and build a solar hot water heater. Their goal is to create a heater that yields the highest temperature change.

In this activity, learners try to float ink on the surface of water to create a pattern and then capture it with absorbent paper.

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

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

In this two-part activity, learners investigate buoyancy, density and surface area as well as biodiversity and the relationship between the structure and function of organisms.

In this activity related to climate change, learners create and explore topographical maps as a means of studying sea level rise.
