You can learn about the Bay from your own backyard.

CBF presents new interactive and social resources to keep teachers, parents, and students connected to the Bay and the watershed from your own backyard, porch, or park.

As we all deal with stay-at-home orders and social distancing, CBF educators are creating new content from their own backyards and home offices so educators and students can keep learning outside and learning about the environment. Below are a variety of student investigations and activities, blog posts on the environment and nature journaling, and videos to help your 'learn at home' efforts.

For a more comprehensive list of curated activities arranged by topic, see our Resources for Teachers and Students page.

Student Investigations & Activities

Great for remote learning or use in the classroom, each investigation integrates video and PDF worksheets with Chesapeake Bay watershed content and curriculum.

  • Underwater Grasses

    You may notice flecks of vegetation as you glide across the water’s surface on the Chesapeake Bay. If you see this, just below the surface may be large beds of underwater grasses. These grasses are a key component of the Bay’s ecosystem. They provide habitat for crabs and fish, add oxygen to the water, prevent shoreline erosion, clarify the water, and serve as a food source for birds. In this video, CBF Captain Bart Jaeger talks about the value of underwater grasses. To learn more, complete the investigation.

  • Freshwater Mussels

    Mussels are similar in many ways to oysters—they are bivalves with two shells that can filter water. But unlike oysters that only live in saltwater, several species of mussels can be found in the Chesapeake Bay watershed’s freshwater rivers and streams. CBF’s Virginia Senior Scientist Joe Wood researches the water quality benefits of these freshwater mussels. In this video, Wood explains why these mussels are good for rivers, how mussels trick fish into helping them out, and other interesting details about these dynamic organisms. After watching, test what you’ve learned by filling out the investigation.

  • Oyster Habitat Observations

    You may know oysters help improve water quality and clarity in the Bay by filtering water, but did you know they also create homes for other critters? Join CBF Educator Kellie Fiala to explore how oysters build three-dimensional reefs and why this habitat is crucial for a wide variety of aquatic life, including crabs and fish. Then try our investigation to learn more about the value of oysters in the Chesapeake Bay.

  • Bay Balance Yoga

    The Chesapeake Bay is an estuary—a place where fresh and saltwater mix that provides a unique habitat for a vast array of birds, mammals, insects, and fish. Get up close and personal with some of the Bay's coolest critters as you contemplate how each is adapted to live in this environment. Then, unroll your yoga mat and have some fun interpreting what you see with our special investigation!

  • Controlling Shoreline Erosion

    Shorelines are an important line of defense for reducing pollution into the Chesapeake Bay. Scientific studies have shown that natural or "living" shorelines braced by grasses, trees, and other vegetation are more than capable of halting erosion while also providing habitat for animals and capturing carbon to reduce the effects of climate change. CBF educators Tiffany and Michael discuss the value of living shorelines, as well as issues related to bulkheads and other armored shorelines. After watching it, see if you can complete our downloadable investigation.

  • Backyard Report Card

    Clean water starts with each of us—in our homes, in our yards, in our neighborhoods, and in our communities. From turning off the faucet when we brush our teeth to mowing lawns less frequently to provide habitat for wildlife, every action matters. Follow along with our video and downloadable investigation to explore how you impact the Bay at home and what you can do to safeguard water quality.

  • Sediment in Streams

    Sediment enters streams and other waterways when it’s picked up by rain washing across the land, as well as from streambank erosion. Too much sediment in the water causes it to become muddy, which restricts the growth of underwater vegetation and can endanger marine life. Watch as CBF Educator Cameron Crannell explores a stream in Virginia and evaluates the water clarity to determine how sediment is impacting the water. Follow up with our Reducing Sediment in Our Streams Investigation.

  • How Forests Help Save the Bay

    The towering trees and other vegetation that make up a forest provide several clean water benefits. But don’t take it from just us! Watch as Avett the Dog explores a forest and explains how he and other animals benefit from the clean air and water they provide. Then check out our Figuring Out Forests and Streams Investigation.

  • An Introduction to Backyard Birding

    The Chesapeake Bay watershed is home to a plethora of well-known birds. Join CBF Educator Tiffany Granberg as she explains how you can identify the birds that may frequent your backyard and other neighborhoods in the Bay watershed. To learn more about the birds in the area, follow up with our Identify Birds in Your Own Backyard Investigation.

  • The Importance of Trees

    Trees are among nature’s most important natural filters. They clean our air and water as well as provide shade and habitat for animals. But how much do you really know about them? Join CBF Educators Liz and Ronnie as they walk you through how trees improve water quality, how to identify them, and how you can analyze tree rings. Then learn more about how important trees are to the Chesapeake Bay and its watershed in the companion investigation.

  • Fish Adaptations

    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 Tiffany Granberg as she goes “fishing” for answers in this video, then take a deeper dive with our Fish Adaptations Investigation.

  • Composting

    When plants or portions of them, such as leaves or branches, die and fall to the ground they undergo a process called decomposition. 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. In this video, CBF Educators Tiffany, Leigh, and Claire explain composting basics, how to build a composter at home, and the different stages of decomposition. You can learn more about composting and its environmental benefits by completing the Composting Investigation.

  • Blue Crab 101

    Blue crabs are the Chesapeake Bay’s signature crustacean. They are delicious to eat, support commercial and recreational fisheries, and are a key piece in the Bay’s food web. They are also fascinating marine animals that are negatively impacted by pollution in the Bay. 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.

  • Reducing Erosion is Good for the Bay

    Every day throughout the Chesapeake Bay watershed, sediment from the ground is being washed or blown away by water and wind. This natural process is called erosion. When erosion happens too quickly—primarily due to water running off from agricultural land or excessive development in cities and towns—it can cause problems in waterways and the Bay. Too much sediment in the water makes the water cloudy, blocking sunlight from reaching underwater grasses. In addition, the excess dirt can potentially smother oysters. In this video, join CBF Educators Morgan and Kate at Maryland’s Calvert Cliffs as they explain why reducing erosion is good for the Bay. After watching, test what you’ve learned by completing our Erosion Investigation.

  • The State of Your Bay

    Every neighborhood is filled with features that can impact water quality in the Chesapeake Bay. In the following video, explore two different neighborhoods with CBF Educators Megan and Claire. They’ll explain how trees, ditches, lawns, roofs, and other things that make up our neighborhoods are related to the health of the Chesapeake Bay. After watching the video, try the State of Your Bay Investigation to explore your neighborhood’s impact on habitats and water quality.

  • Spring Peepers

    Follow along with CBF Educator Liz Glaston as she tracks down the source of the evening chorus of high-pitched peeps that rings out from marshy woodlands in the spring—a tiny tree frog called the northern spring peeper. Then explore the importance of the small, rain-fed wetlands they call home and try your hand at composing some "Peeper Poetry" with our Spring Peepers Investigation.

  • Freshwater Wetlands
