SeaTrek Programs

Program Summary

Living with our beaches and dunes – learning about resilience in the face of constant change

The sandy beach and dune  environment is introduced to the audience through a series of activities that include a learner-appropriate introduction to how scientists define a beach-dune system, followed by hands-on explorations that can cover topics such as sources of beach sand (one end of the rock cycle), links between waves, tides and how beaches and dunes change through the year, challenges presented by sea level rise, beach and dune ecosystems, and how to encourage more resilient coastal development. The emphasis, scientific concepts and depth of the discussion increases with the age and developing skill set of the audience. Data collection activities and guides for later analyses are available for teachers through special arrangement.

Audience: Can be targeted to K-5, 6-8, 9-12, and to Adults through the SeaSpeaks program

We offer two programs on the Great Bay Estuary. One targeted for the K-6th grade audience and the other for 7th graders to adults.

Audience: Grades K-6

The Great Bay Estuary has played a defining role in New Hampshire's history and economy since 1623, but how does the estuary itself work, and what kinds of creatures call it home? This interactive program uses props, short video clips, and illustrative photos to show students how different plants and animals survive in one of earth's most challenging environments (imagine your house being flooded and drained twice each day).

We introduce the Great Bay Estuary's three main habitats: eel grass meadows, mud flats, and salt marshes, and then challenge students to explain the different adaptations found in each. Why are the legs of a great blue heron different from those of an osprey? What does a clam do exactly when there's no water left at low tide? How can marsh grass grow in such salty water? 

Following the 15 to 18-minute PowerPoint presentation on the Great Bay Estuary and its relationship to the coastal watershed, students rotate through two (or sometimes three) hands-on activities which could include:

• an up close and personal encounter with a live horseshoe crab
• a hands-on exercise that visually illustrates what a watershed is, how different sources of pollution can affect it, and the positive effects of vegetative buffer zones
• a history portion about salt marsh haying and how the antique tools were used
• a tower exercise representing the estuarine ecosystem and the effects of different kinds of pollution on the health of the estuary
• a guessing game exercise that reinforces the extreme lengths of time it takes for different polluting objects to be reabsorbed into the environment

Audience: Grades 7-12, Adult

In a PowerPoint presentation we introduce the audience to the estuary and watershed concepts and how everyone living in a watershed area affects the health of that watershed, in this case the Great Bay Estuary.  This estuary is a fascinating environment consisting of three main habitats which are affected twice daily by the tidal flow.  During the presentation we address the following questions:

• What are some of the plants and animals that live in the estuary?
• How have they adapted to this fluctuating environment?
• What happens to the estuary in the event of an oil spill or heavy rain?
• What are some examples of estuary pollutants?

Discussion involves the science behind the factors which affect the health of the estuary over time.  Students are introduced to projects underway to restore estuary habitats to a more healthy condition (eelgrass and oyster reef restoration).

Hands-on activities following could include:

• Estuary metaphors (a box of cereal is like the estuary because...)
• Match-ups (Average salinity = 26 ppt; Freshwater input/Saltwater input = 17%, 83%)

Audience: Elementary School

The life-cycle of a lobster is explored through a series of images in this dynamic program. The history of harvesting lobsters is outlined and the process of catching lobsters in traps is demonstrated for the audience.

Participants have the opportunity to examine lobster traps, handle a live lobster and learn how lobstermen measure and band lobsters for the market.

Through discussion, participants are encouraged to consider the balance between protecting the lobster species, providing a livelihood for lobstermen and ensuring that we continue to enjoy this delicacy from the sea.

Program Summary

Marine mammals are among the most charismatic and interesting animals on the planet! This docent team can tailor a program to meet the needs of your curriculum by either focusing on Cetaceans (Whales, Dolphins, Porpoises) or on Pinnipeds (Seals, Sea Lions, Walruses.)  After submitting a request for a Marine Mammals SeaTrek, you will be contacted regarding your preferences.

Each engaging program begins with a PowerPoint presentation that illustrates the physical and behavioral characteristics of the animals being covered. Docents will interact with participants by asking questions and encouraging thoughtful discussion. Participants will then be broken into small groups for a rotation of hands-on activities that are designed to provide students with opportunities to enhance their understanding of concepts presented during the PowerPoint. The activities (which are chosen from the list below) will be determined by age group of students, as well as time, space, and docent availability.

Audience: Kindergarten, Elementary
Length: 45 minutes

Did you know that octopuses are masters of camouflage, able to change their color, shape, and texture in the blink of an eye? They are also amazingly intelligent, able to use tools and solve a variety of problems.

This captivating program uses pictures, brief video clips, and props to teach kids the basics about octopuses (anatomy, size, diet, habitat, predators) and to explore their intelligence and wide range of defenses (methods of camouflage, squirting ink, and jet propulsion).

Kids get to learn a new word, "chromatophore," and how the chromatophore works to change an octopus's skin color instantly. There's even a short song about the chromatophore.

Following the 20-minute interactive presentation, kids get up and participate in two hands-on activities that reinforce the concepts in the presentation.

Audience: Grades 4 - 8

Program Summary

Plate Tectonics is the most exciting geologic discovery of the 20th Century! Geologists and oceanographers are continuing to make new discoveries every year. This science is unfolding before our eyes today.

Volcanoes! Earthquakes! Tsunamis! Enormous forces burst out of the earth and create havoc and destruction. Learn why these catastrophes happen and where they are likely to occur in the future. The Plate Tectonics SeaTrek will explore the ever-moving surface of our dynamic planet: Earth.

Although the surface of the earth appears to be rigid and stationary, scientists have found that it is constantly in motion. The surface is broken into large slabs or plates that are moved around by heat energy from the interior of the planet. The plates spread apart and come together, creating ocean basins, mountain ranges, volcanic islands--all the major geologic features that we see today. The movements of the plates are very slow--barely an inch or so per year. But over the billions of years of Earth's history, the surface has constantly been transformed.

Plate Tectonics presents the key elements of this scientific concept that has revolutionized our understanding of the dynamic planet upon which we live.

Program Outline

This program emphasizes student involvement. A brief introduction challenges students to think about what causes volcanoes, earthquakes and tsunamis. After explaining the basic scientific theory, students are asked questions pertaining to important plate tectonics topics to think about as the presentation proceeds.

A PowerPoint presentation provides visual evidence of ongoing plate movements while being complemented by a series of hands-on activities to maintain interest. These activities include:

• A timeline rope with tags marking important events from Earth's formation to the present day.
• A global map puzzle.
• A global plate puzzle.
• An inflatable globe with plate boundary markings.
• A model showing the breakup of the supercontinent, Pangea, 200 million years ago to the current continental locations.
• A volcano visual aid.
• Two models showing how these gigantic plates move. The plate motions cause earthquakes, volcanic eruptions, and tsunamis as shown in the pictures.
• Finally, the questions asked at the beginning are reviewed with student participation

Program can be tailored to the age and academic background of the students. To enhance the presentation's effectiveness, it is very helpful if the lead teacher at the school contacts one of the program presenters to help ascertain target areas. The focus of the 45-minute Rocky Shore Program can be either Seaweeds or Invertebrate Animals. If the school would like to have both presentations, we then recommend two sessions or a 90-minute period.

Program Summary

Spanning the area between the low and high tide lines, the intertidal zone of the rocky shore of the New England seacoast is an ecological treasure trove of organisms whose survival is challenged by a variety of extreme conditions including crashing waves, hours of exposure to air, temperature and salinity fluctuations, and predation from both land and sea. Yet even in these conditions there is a rich variety of marine organisms that have adapted well to this ecosystem.

A Power Point presentation sets the stage for understanding the organisms and the ecological interactions that impact this dynamic ecosystem. Participants then have the opportunity for detailed examination and handling of many of the common live seaweeds and invertebrates that inhabit the different areas of the intertidal zone between the low and high tide lines. In addition to seeing a diversity of red, green and brown seaweeds, students will also get to observe such organisms as snails (periwinkles and dog whelks), sea stars, sea urchins, and green & Asian shore crabs, among others. Through their encounters with these intertidal organisms, students will be encouraged to observe and discuss the adaptations of each organism that help ensure that it remains moist, feeds adequately, avoids predators and stays put amid tides and crashing waves.

Sea chanteys are fun songs, but in the old days of the tall-masted sailing ships they were the work songs by which the sailors labored in unison to hoist the sails, haul up the anchor and pump the bilge. It was exhausting work, icy cold in the Arctic gales, sweaty in the tropic calms. But the chanteys (from the French verb, "to sing") told tales of high adventure - of harpooned whales that dragged them on a "Nantucket sleigh ride," of pirates they fought on the high seas, of girls they wooed in ports around the globe. For hard-bitten men, they were great romantics!

It is the special joy of the Chantey Singers to bring alive the folklore of the great days of sail - politics, economics, science and fun, all in one rousing package!

Previous Sea Chantey audiences:

• Elementary and middle schools throughout the Seacoast and beyond
• Public libraries
• Retirement communities and nursing homes
• Civic, professional and community groups

The choice of songs are customized for the age range of the audience.
