Environmental Learning Outside the Classroom (ELOC) Environmental Learning Outside the Classroom (ELOC) This guidebook provides lesson ideas and activities to get students engaged with outdoor learning. Created by the Virgin Islands Marine Advisory Service (VIMAS), an extension arm of the University of Puerto Rico’s Sea Grant College Program. For more information, contact: Howard Forbes Jr. (VIMAS Coordinator) ph: 340-693-1672/340-513-7203 E-mail: [email protected] Website: vimas.uvi.edu VIMAS Lesson Plan Topic: Marine Invertebrates / Coral Reefs / Marine Protected Areas Grade level: 5th to 12th Estimated time for activity: Lecture: Interactive 30 minutes, Activity: 30 minutes Information Purpose: Procedure: To teach students about marine Students will have an opportunity to interact invertebrates and how they differ from with marine life both in a water table as well as Activity vertebrates. To educate students on how in their natural environment via snorkeling. to identify various marine species. Students will be actively engaged in discussion about the various marine invertebrates. After exposure students should be able to identify at least 3 marine invertebrates and name something special about each. By dispelling myths associated with some of the marine invertebrates, students should be more comfortable with snorkeling and handling Assessment of marine invertebrates.

Touch Tank Outdoor learning activity A touch tank is an aquarium that allows its observers to interact with the marine organisms within. Each organism within the tank plays an important role to maintaining the ecosystem balance, much like a natural environment. Some organisms provide habitat for others while some help clean off parasites. Species Identification Can you identify each species? • Brittle star • Pencil urchin • Sea cucumber • Sun anemone • Long-spined urchin • Feather duster worm • Lettuce sea slug • West-Indian sea egg • Decorator crab • Cleaner shrimp • Arrow crab • Coralimorph Species Scavenger Hunt Team activity In groups, your snorkel guide instructor will facilitate a guided tour around Brewers Bay. Along this trail, you will encounter colored markers to point out locations on the trail that have a Group Discussion Topic: significant amount of • How do you think an oil spill could life. negatively impact all of these organisms? Precaution Notice A B When you enter the marine ecosystem, just like any other ecosystem, caution should always be exercised. Fire coral (A), Long spine sea urchins (C), and Fire worms (E) should not be touched. D Rockfish (B) have venomous spines and look very much like a rock. They can often be found on the ocean floor camouflaging with rocks and sand. Just like the barracuda C (D), if you encounter one, E don’t panic. Just freeze and back away slowly. These creatures will not pursue you unless you have food in your pockets! Coral Reefs Do you know what a coral is? Which of these objects are corals? Corals are marine organisms that provide a number of ecosystem services such as serving as important habitat for fish, shoreline protection A B from waves, and even medicine. However, our reefs are being threatened by increased water temperatures, coral diseases, C and coastal pollution. What D are some things you can do to help protect our coral reefs? Threats to Coral Reefs Healthy coral reefs, pictured on the left. However, threats from sediment and coral disease are causing a significant decline in coral reef populations. Researchers at UVI are working diligently to understand what is influencing this decline. Non-sustainable Fishing Practices Many ecosystems are dependent on the services provided by their inhabitants. Overfishing is one such problem that has negatively affected coral reefs. By using trawl nets, fish that aren’t intended to be caught are netted in the process. Commercially Important Fish These marine organisms are all commercially important species; humans utilize these species as food sources. However, due to non- Nassau grouper Spiny lobster sustainable fishing practices, many of these fish populations have been significantly decreased. These organisms such as the parrotfish, serve ecological Stoplight parrotfish Queen conch roles such as consuming algae that could otherwise smother and kill coral as well as producing the beautiful sand on the beach. Red snapper Marine Protected Areas Marine protected areas (MPA) are protected areas of seas, oceans, or large lakes. MPAs restrict human activity for a conservation purpose, typically to protect natural or cultural resources. Discussion topic: How do you think MPAs help the environment? They increase biodiversity (the number of “different” species found within an ecosystem. They also allow for juvenile (young) fish to grow up to maturity and reproduce. One Fish, Two Fish What you’ll need: • Large playing area (beach) • Hoola hoops To play, have 2 students volunteer to be trawlers which collect fish; all other students will be fish. The object is for the trawlers to capture all of the fish and the fish can only walk, not run. Any fish caught becomes a trawler and all trawlers must be connected at all times. This usually ends after 2-3 minutes. When the students reconvene, discuss with them ways we can better protect the fish; i.e. introduce the hoola hoop as a marine protected area that fish can be protected in for approximately x seconds. See how many other solutions the students can come up with. Coral Reef Snorkel Students will be provided with snorkel gear. Once all students are suited, beginning from the MSC dock, students will near the coral reefs close to the shoreline/dock. Be on the lookout for any fish and observe everything in its natural habitat. Precaution Notice A B When you enter the marine ecosystem, just like any other ecosystem, caution should always be exercised. Fire coral (A), Long spine sea urchins (C), and Fire worms (E) should not be touched. D Rockfish (B) have venomous spines and look very much like a rock.

  • Gastropod Bingo
    Gastropod Bingo Purpose of activity: To review gastropods (mollusks with one shell or no shell) Target age group: 8-13 Time needed: Flexible-- you can play just one round or several Materials needed: A copy of the picture page for each player printed onto card stock, scissors, tokens to place on the squares, one copy of the clue pages How to assemble: 1) Make one copy per player of the picture page, printed onto heavy card stock. 2) Cut apart the pictures. TIP: If you are making many copies of the board pieces so you can play with many students, number the sets (put a number 1 on the backs of all the cards in one set, a number 2 on the cards in another set, etc.) so that if they get mixed up they are easy to sort out again. It is surprising how easily the cards can get mixed up. How to set up the board: Here are three different ways to set up the board. You can use just one way, or you can use a differ- ent set up for each round. 1) Standard 4x4 bingo board: Have the players choose 16 of the 20 squares and arrange them into a square. 2) Five small 2x2 squares: Have the players arrange their 20 squares into five separate 2x2 squares. They must fill all four spaces in one of those 2x2 squares to get a Bingo. 3) 5x5 square with free space: Cut an extra square for each player, to use as a FREE square in the middle.

  • Marine Invertebrates As Indicators of Reef Health
    MARINE INVERTEBRATES AS INDICATORS OF REEF HEALTH A STUDY OF THE REEFS IN THE REGION OF ANDAVADOAKA, SOUTH WEST MADAGASCAR Anna Hopkins MSc Conservation Science September 2009 A thesis submitted in partial fulfilment of the requirements for the degree of Master of Science and the Diploma of Imperial College London i ABSTRACT Coral reefs are under increasing pressure from anthropogenic threats, especially over- harvesting. Certain invertebrate species are considered indicators of ecological change and any possible disturbance to the reef can be gauged by monitoring their abundance. The densities of eight invertebrate species were measured over a four year period within three types of reef; fringing, barrier and patch, surrounding the area of Andavadoaka, Southwest Madagascar. General linear mixed effect models indicated complex patterns of abundance in relation to annual, seasonal and spatial variation in all species, with season being the weaker explanatory variable. There was no evidence of ecological disturbance in any of the reef types and echinoid densities were comparable to those found in protected areas. Acanthaster planci was found in very low densities and therefore not an ecological threat. Echinostrephus was found to be the dominant echinoid throughout the area. Harvested species T. gigas and C. tritonis were uniformly rare at all sites but compared to reefs in Southeast Asia are in healthy numbers. Holothurians have decreased in number although recent increases have been noted on patch reefs. Patch reefs were found to harbour the healthiest abundance of echinoids and harvested species. Fringing reefs had lower densities of all species possibly as a result of more intense harvesting effort.

This identification guide is the result of intensive sampling of shallow-water habitats in Bocas del Toro during 2003 and 2004. The guide is designed to aid in identification of a selection of common macroscopic marine invertebrates in the field and includes 95 species of sponges, 43 corals, 35 gorgonians, 16 nem- erteans, 12 sipunculeans, 19 opisthobranchs, 23 echinoderms, and 32 tunicates. Species are included here on the basis on local abundance and the availability of adequate photographs. Taxonomic coverage of some groups such as tunicates and sponges is greater than 70% of species reported from the area, while coverage for some other groups is significantly less and many microscopic phyla are not included.

  • Marine Invertebrates – Introduction
    Appendix 4, Page 1 Marine Invertebrates – Introduction Marine ecosystems worldwide are being altered by human disturbances such as overfishing (Botsford et al. 1997; Jackson et al. 2001; Pauly et al, 2002; Myers and Worm 2003) coastal shoreline development, climate change, and eutrophication (Howarth et al. 2000; Rabalais et al. 2002), and these impacts are beginning to be felt in Alaska. Achieving sustainability of resources, economies, coastal communities and the ecosystems in which these are all embedded requires conservation strategies that acknowledge the complex social and ecological interactions that drive marine ecosystem dynamics (Scheffer et al. 2001; Walker et al. 2002). The focus of this template is on the approach that will be used for conservation planning, one that encompasses the ecological relationships among multiple species and habitats.

Students will identify that some animals can live in more than one habitat. Materials Bubble liquid Bubble blower (suggested) Examples (photos or props) representing filter-feeding organisms Background for Instructors Plankton is defined as floating plants and animals that cannot move against the current under their own power. We usually refer to any floating, small or microscopic organism (plant or animal) as plankton. Plankton is divided into phytoplankton (plant plankton) and zooplankton (animal plankton). Phytoplankton is made up of single-celled and multi-cellular green organisms that use photosynthesis to live and grow from solar energy, in much the same way plants do on land. Phytoplankton lives and dies floating around on the currents of the world’s oceans, bays, and estuaries. Zooplankton includes a vast array of tiny animals that feeds on phytoplankton and one another. Zooplankton includes many animals that never get very large, eggs of fish and marine invertebrates, and many larval forms of familiar sea creatures (crabs, lobsters, jellyfish) that leave the plankton as they mature. Many types of marine animals feed by forcing sea water through filters to remove edible particles from the water. This method of capturing food is known as filter-feeding. Bivalves, such as clams and mussels draw water into their body through a siphon, pass it through a series of filters, and expel the water, digesting the microscopic organisms that were floating in the water.

In an initiative to help further our understanding, invertebrate surveys over the past seven years have now revealed more than 500 species, many of which are endemic. This is an essential reference guide to these species. Illustrated with hundreds of representative photographs, it includes brief narratives on the biology and ecology of the major taxonomic groups and characteristic features of common species. It is primarily aimed at scientifi c observers, and is intended to be used as both a training tool prior to deployment at-sea, and for use in making accurate identifi cations of invertebrate by catch when operating in the HIMI region. Many of the featured organisms are also found throughout the Indian sector of the Southern Ocean, the guide therefore having national appeal.
