Learn Outside, Learn at Home

In order to support you during this unprecedented time, CBF educators are hard at work creating new ways for educators and students to keep learning outside and learning about the environment. Over the coming weeks we will be sharing new interactive and social resources to keep you connected to the Bay and the watershed from your own backyard, porch, or park.

Looking to learn more about the Bay? These curated activities are arranged by topic to encourage curiosity and love of the Chesapeake Bay. Teachers and students will find these resources helpful for learning more about the Chesapeake Bay watershed. We will be updating this page with more resources and videos throughout spring 2020.

The Watershed

The Chesapeake Bay's 64,000-square-mile watershed covers parts of six states and is home to more than 18 million people. 

  • Need a visual? Check out this Chesapeake Bay Watershed poster.
  • How does CBF protect the Chesapeake Bay Watershed? Through the implementation of the Chesapeake Clean Water Blueprint.
  • Polluted runoff is a huge issue facing the watershed, what we do on land ultimately impacts our water and waterways emptying out into the bay. In our video Green vs. Gray Filters, CBF Educator Nathan Hesse examines different gray and green filters that make up the landscape and how they affect water quality. After watching the video, try our investigation When Rain Hits the Land.
  • It’s difficult to imagine the size and scale of our watershed. To get a better picture of how one drop of water impacts the Bay, watch this video. Need more practice? Try this Bay-sic Ratios activity.
  • In our video Reducing Erosion is Good for the Bay, join CBF Educators Morgan and Kate at Maryland’s Calvert Cliffs as they explain why reducing erosion is good for the Bay. Then test what you've learned with our Erosion Investigation.
  • Trees are among nature’s most important natural filters. But how much do you really know about them? CBF Educators Liz and Ronnie will walk you through the wonders of trees in our video The Importance of Trees. Follow up with the companion investigation to learn more.

  • Riparian buffers, which are trees, shrubs or other vegetation along a stream or waterway, are an important tool to improve the health of the Chesapeake Bay ecosystem. Watch our video as CBF Field Educator Liz Yocom details how riparian buffers can improve stream health and identifies several macroinvertebrates that can be found in streams. After watching the video, complete the Riparian Buffer Investigation.
  • Join CBF Educators Maya, Ochae, and Nate in our Nutrient Scavenger Hunt as they scour their neighborhoods looking for sources of nutrient pollutants and the methods used to reduce them. Afterwards, use the Nutrients: Too Much of a Good Thing Investigation for your own scavenger hunt. Can you find sources of nutrients and stormwater management best practices in your own neighborhood?
  • In addition to our watershed, did you know we also have an airshed? Check out the map on our airshed web page to get a sense of how big our airshed is –it's bigger than you think!

Habitats of the Watershed

Fresh Water Streams

As the saying goes, "everything flows downstream." The Chesapeake Bay is fed by 50 major rivers and streams, with more than 100,000 smaller streams, creeks, and rivers throughout the watershed. Five major rivers—the Susquehanna, Potomac, Rappahannock, York, and James—provide almost 90 percent of the freshwater to the Bay. All of these waterways, large and small, provide habitat necessary for more than 400 species of fish and supporting hundreds of animal species. If we are to "Save the Bay" we must also save the thousands of waterways that flow into it.

  • Find out more amazing facts about the 64,000 square miles we call the Chesapeake Bay watershed.
  • Check out this map of all the major river watersheds of the Chesapeake Bay.
  • The Susquehanna River is the largest tributary to the bay, providing almost half of the Bay’s freshwater!
  • Check out this graphic about the mighty Susquehanna.
  • Unfortunately, some of these rivers are seriously polluted and at risk, because their watersheds are covered with hardened surfaces, like roads, roofs, and parking lots. Is your local waterway at risk? Find out!
  • In our Student Investigation & Activity: Freshwater Stream Health, follow CBF Educator Doug Walters as he explores a tributary stream and discusses how to evaluate its health. Then see if you can identify key factors related to stream health
  • Students can make a difference, in fact, they are champions of the Bay, its rivers and streams.  A group of Pennsylvania student leaders even wrote a bill to designate the Eastern hellbender as the official state amphibian of Pennsylvania!
  • Why freshwater mussels good for rivers and streams? How many species of freshwater mussels are there in the Bay watershed? Want to Ask an Expert? CBF's Virginia Senior Scientist Joe Wood shares why he loves these amazing mollusks—and why you should too!
  • Are you looking for a way to help the Bay? Here are 12 things you can do today to clean up rivers, streams, and the Chesapeake Bay.

Wetlands

Wetlands are the link between land and water. The unique ecosystems that support a wealth of plant and animal life. Wetlands are not always wet year-round, and some of the most important wetlands are wet for only part of the year. In addition to providing essential habitat for fish, birds, and other wildlife, wetlands also provide valuable economic benefits, such as controlling floods, filtering pollutants, and providing recreational opportunities.

Forests

Like the Lorax, CBF speaks for the trees! Trees, forests, and forested (or riparian) buffers are the front line of defense when it comes to preventing erosion and protecting water clarity. CBF supports both healthy forests and rivers and streams by building and restoring forested buffers (multiple rows of native trees, shrubs, and grasses) along streams and rivers.

Oysters and Oyster Reefs

Food. Filter. Habitat. Oysters are the backbone of the Bay, providing habitat for Bay creatures, a food source for both animals and humans, and the essential ecosystem service of filtration. Not sure where to begin? Watch Back to Baysics: Oyster Sanctuaries.

Underwater Grasses

Get introduced to underwater grasses by watching this Back to Basics video! Like oyster reefs, underwater grasses provide essential habitat for many of the Bay’s most charismatic species—like pufferfish, pipefish, and seahorses!!! Underwater grasses are also a vital food source for migrating waterfowl. In addition, underwater grasses help to brace and support land from waves, slowing them down and reducing erosion.

Wildlife

Blue Crabs

  • Blue crabs are the Chesapeake Bay’s signature crustacean. Watch as CBF Virginia Field Manager Ken Slazyk describes blue crabs’ key features and their life cycle in this animated video. By completing the Blue Crab 101 Investigation you can learn more about this important species.

Fish

  • What are the keystone species of the Chesapeake Bay? Many of them are in fact, fish! From striped bass (also called rockfish) to Atlantic menhaden and American shad, fish play a crucial role in the Bay’s ecosystem and food web.

    • Get back to basics, learn about the fins of a fish with this fun video or using the Know Your Fish tool.
    • The Chesapeake Bay is home to fish of all shapes and sizes, each species uniquely adapted for the conditions where it lives. What can you learn about a fish’s food source, habitat, and lifestyle just from looking at it? Join CBF Educator Leigh Auth as she goes “fishing” for answers and take a deeper dive with our Fish Adaptations Investigation.

    Birds

    Waterfowl and other birds migrating along the Atlantic Flyway stop in and around the Bay, finding food and shelter in coves and marshes. The Chesapeake Bay watershed is also a major nesting area for the threatened bald eagle, the once-endangered brown pelican, double-crested cormorants, and home to the world's largest population of another raptor, the osprey, with more than 2,000 nesting pairs. Watch our video of a baby osprey feeding on a menhaden at CBF's headquarters at the Philip Merrill Center.

    • Want to get up close and personal with one of the Bay’s most iconic bird species?  Check out the Chesapeake Conservancy's Osprey Cam to get live video footage from CBF’s headquarters at the Phillip Merrill Center.

    Composting

    • As plants decompose, their organic materials break down, which returns nutrients to the soil. When humans control the process of decomposition it’s called composting. Watch as CBF ducators Tiffany, Leigh, and Claire explain composting basics, how to build a composter at home, and the different stages of decomposition in Student Investigation & Activity: Composting.

    Student Action Projects

    Fix Your Schoolyard Bare Spots (PDF, 12 pgs, 1.2 MB) Bare spots are places where vegetation (such as plants, shrubs, grasses, flowers) no longer exists in the soil. Bare spots come in all shapes and sizes. The outcome of having any type of bare spot is the same: storm water hits the ground and is not able to soak in to the land. Use this step-by-step guide to fix the bare spots in your school or home yard.

    Build Your Own Rain Barrel (PDF, 4 pgs, 612 KB) Capture rain water from downspouts to reduce runoff and have a water source during droughts using this easy step-by-step guide.

    Build Your Own Rain Garden (PDF, 8 pgs, 627 KB) Add colorful habitat to your schoolground while keeping sediment from choking local streams by using this easy step-by step guide.


    CBF Oyster Restoration
    —The Oyster Corps is a diverse collection of citizens and students dedicated to the common purpose of restoring oysters to the Chesapeake Bay. There are many ways people can help rebuild the Bay's depleted oyster populations, and participation in any of these activities makes you part of this grassroots movement. Explore our programs in Maryland and Virginia.

    Storm Drain Stenciling—Many people are not aware that most storm drains lead directly to waterways that dump into the Bay. You can help clean up the Bay by stenciling a message that will help members of your community remember that nothing but rain water should enter the storm drains. Storm drains are not trash cans: whatever is dumped into them ends up in the Chesapeake Bay. Learn more about how to participate in this important project.
