Seagrass Angelfish Seacucumber Elkhorn

Program Components

Our STEM core curriculum consists of seagrass, mangrove, and coral reef ecology. Evening discussions on coral reef ecology & fish identification, along with labs on invertebrate diversity and zooplankton identification are also part of the core curriculum. The discussions are the same regardless of the grade level, but the content detail and delivery are adjusted to the audience. Following are short descriptions of each of our program components.

Click here for a matrix showing which components are suitable for your students' grade level and here for a summary of each component of our core curriculum. We also have a summary of advanced programs, components incorporating service learning, and programs utilizing research techniques.

CORE: Seagrass Ecology Discussion & Field Trip

The discussion focuses on the importance of a healthy seagrass community, threats facing seagrasses, and familiarization with about 50 of the organisms associated with this area. Proper snorkeling techniques are also shown. Students are then taken to a seagrass flat to snorkel in this commercially crucial habitat where spiny lobsters, stone crabs, and baitfish are numerous. Usually this is the first field trip in the program, so students' first snorkeling experience is in the calmer waters of the seagrass areas. In some programs, the seagrass and mangrove field trips are combined. All grades. PDF Summary

ADVANCED Seagrass Ecology: The advanced version of the Seagrass Ecology discussion includes instruction on conducting science based seagrass surveys and a full analysis of data collected. Grades 9 and above PDF Summary

CORE: Mangrove Ecology Field Trip

Mangroves form a biologically rich and environmentally crucial transition zone between land and sea. On the way to the mangrove snorkeling site, instructors discuss the importance of the mangrove habitat and the plants' unique adaptations. At the site, students explore the intricate, fascinating world of life on and among the mangrove prop roots. Instructors collect small invertebrates for further examination and discussion back aboard the boat. In some programs, the seagrass and mangrove field trips are combined. All grades. PDF Summary

ADVANCED Mangrove Ecology Field Trip: We add a sediment analysis lab into our basic mangrove ecology programs. Students collect sediment cores from a red and black mangrove for analysis. Grades 9 and above. PDF Summary

CORE: Coral Reef Ecology Discussion & Field Trip

The Coral Reef Ecology discussion precedes the first trip to the coral reef. It includes information on the biology of reef-building corals, the abiotic parameters necessary for reef formation, types of corals, reef preservation, and snorkeling etiquette. Students are then taken about four to five miles offshore to snorkel on a variety of coral reefs, such as Key Largo Dry Rocks, Grecian Rocks, and Molasses Reef. All grades. PDF Summary

ADVANCED: There are two Advanced Coral Reef Ecology discussions, both suitable for grades 9 and above.

Advanced Coral Reef Ecology is our basic Coral Reef Ecology discussion with the addition of a discussion on identifying bleached corals and getting familiar with the protocols used by Bleachwatch to report such bleached corals. The subsequent field trip includes searching for, identifying and reporting bleached corals. PDF Summary

Coral Reef Ecology II: A Closer Look is an advanced discussion for students who have already done either our standard or advanced Coral Reef Ecology discusion. The topic expands on concepts taught during our basic program and the discussion encourages students to beigin to ask questions about their coral reef observations. After a powerpoint discussion, students have the opportunity to snorkel two different coral reef sites with a checklist of specific organisms, behaviors and items to look for. PDF Summary

CORE: Field Identification of Reef Fish Discussion & Field Trip

This discussion is an interactive presentation on fish morphology, habitat, and behavior and provides students with the "field marks" needed to identify a fish. With drawn visual aids and slides of local fish, students practice their identification skills prior to their second snorkeling trip to the reef. All grades. PDF Summary

ADVANCED There are two advanced fish identification options, both suitable for grades 9 and above.
The REEF Fish Survey program is an extension of our Fish ID program, using the citizen science opportunity created by Reef Environmental Education Foundation (REEF). In addition to our core program, students will learn REEF's "Roving Diver" technique. Students will go to the reef to conduct surveys. An additional option is to have students take a fish ID quiz; if students pass the quiz they can enter data into the REEF database as Level 2 surveyors. PDF Summary

Parrotfish Feeding Survey: In addition to our core Fish ID program, students will be taught the protocols for conducting a parrotfish feeding survey. While at the reef, students will record appropriate data, all of which is sent to Dr. Deron Burkepile of the University of CA - Santa Barbara. PDF Summary

CORE: Invertebrate Diversity Lab

Students collect an algae covered rock from the beach off MarineLab and take it into the lab to "shake" it into a tub of seawater. The various free-swimming and sessile creatures and plants are identified and classified into phyla. The biological significance of diversity is discussed. All grades PDF Summary

ADVANCED: Diversity Indexing Lab, AP Grades 9 and above. This expanded version of our Invertebrate Diversity Lab takes that lab one step further: counting species and developing a Simpson's diversity index for the target algae-covered rock and extrapolating the data to calculate a diversity index for Largo Sound. The instructor concludes with a discussion of why the index may be different, the negatives and positives of using diversity indices, and its applicability to other habitats. Depending on time and type of program, students may compute Simpson's Index in other marine habitats they visit during their program, such as Rodriguez Key. PDF Summary

Rodriguez Key Zonation

Rodriguez Key is just offshore of Key Largo and features an interesting bottom community that is based on the coralline algae Neogoniolithon. Students snorkel the area and instructors collect large chunks of the Neogoniolithon. Back at the boat, students break up the algae to find and identify the invertebrates inside. The second stop on this field trip is usually to a patch reef community, populated with tropical fish and smaller corals, sea whips, and sea rods, or a small wreck with resident nurse sharks, rays, and balloonfish. All grades. PDF Summary

ADVANCED Grades 9 and above. Students can derive a diversity index from the organisms collected at Rodriguez Key, and compare it to the index previously derived from the diversity indexing lab.PDF Summary

Water Quality Lab

During this lab, students will be taught about the importance of abiotic conditions such as water quality parameters (salinity, temperature, pH, dissolved oxygen, ammonia, and clarity), the healthy levels for water quality parameters, and techniques for measuring water quality parameters. Students will then get the opportunity to use the instruments to test water quality of four different samples of water, representing four different bodies of water (North Sea, South Sea, Key Largo drinking water, MarineLab fish tank). The measurements from the water samples will then be compared and explained. Water quality testing is done in the field at field trip sites and the data is recorded. MarineLab is part of the GLOBE program and field sample results are uploaded to their database. Grades 7 and above. PDF Summary

ADVANCED Grades 9 and above. This version of the water quality lab gives more advanced students a more in-depth understanding of water quality parameters regularely measured in water quality studies and give these students greater exposure to scientific tools used to test for water quality. MarineLab has acquired more advanced meters and probes, including a YSI 556MPS with probes for temperature, salinity/conductivity, DO, and pH. Water quality measurements collected in Florida Bay by AP level students are submitted to Florida International University as part of an ongoing study conducted by the Southeast Environmental Research Center's Water Quality Monitoring Network.
