Tide Pools; An Ever Changing Ecosystem GRADES: 3-5; Multiage PROGRAM DESCRIPTION: This program will teach students about the importance of tide pools and the different adaptations that animals need to survive there. Rocky shores and tide pools are the division between land and sea that provide protection from storms, provide a place for animals to live and act as a measure for overall ecosystem health. *Before your class visits the Oklahoma Aquarium* This guide contains information and activities for you to use both before and after your visit to the Oklahoma Aquarium. You may want to read stories about tide pools and their inhabitants to the students, present information in class, or utilize some of the activities from this booklet. 1 Table of Contents Tide pools abstract Educator Information Vocabulary Internet resources and books PASS/OK Science standards Accompanying Activities Gak Animal Hold On Tight Invertebrate Name Decoder Raisin Populations Tidepool in a Bucket Rocky Shore (Label the Plants and Animals) 3 4 5 6 7 9 10 11 14 15 16 2 Tide Pools; An Ever Changing Ecosystem: ABSTRACT Tide pools are located around the world where the land meets the sea, especially where there are rocky shores. The tide pools form in the rocks as the tides come in and out. They are valuable to humans because they are a place where people can fish. They offer the opportunity to study population dynamics, are an indicator of overall ecosystem health, hold animals that we enjoy eating and provide a barrier between the sea and the shore. Animals that are found in tide pools have special adaptations that allow them to withstand the harsh, changing conditions. Some of the factors that may limit where organisms can live are; changes in temperature, salinity, oxygen, wave action and predation. Some of the adaptations that help animals survive this harsh environment are: shells to hold in water and provide protection, mucus secretions that act as glue, vascular systems that hold in water, camouflage, the ability to clone themselves, stinging cells and the ability to retract appendages. The rocky shores are divided into different zones. These zones are defined by the amount of time they are exposed to the air. The zones are the splash zone, the mid zone, high zone and low zone. The splash zone is exposed to air about 70% of the time while the low zone is covered in water the majority of the time. Gravity that is exerted by the sun and the moon are responsible for causing tides along with the earth’s rotation. Gravity pulls water away from Earth while inertia tries to keep the water on Earth. This is high tide. The sides of the earth that are not in line with the moon will experience low tides. All shores will experience at least one low and high tide each day. Some of the organisms that can be found in tide pools include but are not limited to marine snails, sea anemones, crabs, algae of various sizes, small fish, barnacles, abalone, octopus and jellyfish. This important ecosystem is under threat because of human carelessness. People are polluting the oceans with trash and chemicals, releasing large quantities of carbon into the atmosphere that are causing climate changes, trampling animals, over harvesting organisms and introducing invasive species. People do not have to be the problem; they can be the solution by doing things like recycling, using less plastic, participating in beach clean-ups, not disturbing organisms, choosing sustainable seafood and supporting laws that protect the environment. 3 Tide Pools; An Ever Changing Ecosystem: EDUCATOR INFORMATION *Tide pools are formed by tides coming in and out. *High tide brings fresh water, oxygen and food to tide pool residents. *Some animals will live most of their lives in tide pools such as the tide pool sculpin. *Seaweed can provide food and shelter to animals, especially during low tide. *Seaweed is a type of algae. There are three different types of algae: red, brown and green. Algae reproduce using spores, they don’t have roots, leaves or flowers and photosynthesize. *Organisms in the tide pools need special adaptations to deal with changes in salinity, water level, oxygen and temperature. * Phylum Cnidaria include animals like jellyfish and anemones. All cnidarians have nematocysts or stinging cells. * Sea anemones are frequently found in tide pools. They are interesting because they can reproduce with gametes or they can clone themselves by budding. They have tentacles that surround their oral disk and stinging cells. *Phylum Mollusca is very diverse. It contains animals such as abalone, mussels, octopus, chitons and limpets. There are 85,000 different mollusks. Most mollusks will have a shell that they make with their mantle. You can find many mollusks in the aquarium, especially in the Amazing Invertebrates Gallery. * Sea urchins have spines around their shell which is called a test. Some urchins have venomous spines. *Tide pool sculpins heavily rely on tide pools. They will live most of their lives in tide pools but will release their eggs into the water at high tide. * Tide pool inhabitants that may be observed in the aquarium are; red abalone, sea anemones, sea stars, brittle stars, giant key hole limpet, sea urchins, hermit crabs. 4 Vocabulary: Adaptation- An alteration or adjustment in structure or habits, often hereditary, by which a species or individual improves its condition in relationship to environment Algae- Any of various chiefly aquatic, eukaryotic, photosynthetic organisms, ranging in size from single-celled forms to the giant kelp. (From Rocky Shore and Tide Pools Encyclopedia) Biodiversity- Species richness; includes plants and animals Climate change- Refers to any significant change in the measures of climate lasting for an extended period of time. In other words, climate change includes major changes in temperature, precipitation, or wind patterns, among other effects, that occur over several decades or longer (EPA) Current- Water that is moving in the same direction Gravity – The force of attraction which pulls things toward each other Habitat- The area or environment where an organism or ecological community normally lives or occurs High zone- The area of the intertdial zone that is exposed to air 70% of the time Intertidal zone- The coast that is underwater during high tide and exposed to air during low tide Invasive species- A species that is not native to the environment that it is currently occupying and directly competing with native species for resources Low zone- This area is covered by water most of the time except during very low tide and is very biodiverse Mid zone- This area is in the middle of the intertidal zone. It tends to be very biodiverse and is covered by water half of the time Radula- A bony tongue like structure common in most mollusks Tide – The regular rise and fall of the ocean that is caused by gravitational pull and orbit of the moon and sun 5 Seaweed- A type of marine algae that includes red, brown and green algae that is held to the bottom of the ocean using a holdfast Splash zone – The area of the intertidal zone that is usually exposed to air and gets splashed by waves Resources: Internet Resources: http://limpetsmonitoring.org/ http://www.scientistinresidence.ca/pdf/lifescience/Aquatic%20Ecosystems/SRP_Aquatic%20Ecosystems_Lesson%202 %20WF.pdf http://www.nytimes.com/2014/07/27/sports/in-hunt-for-red-abalonedivers-face-risks-and-poachers-face-the-law.html?_r=0 http://www.st-andrews.ac.uk/news/archive/2012/title,88759,en.php http://www.nps.gov/pore/naturescience/intertidal.htm http://www.futurity.org/mussels-a-new-model-for-medical-glue/ http://oregontidepools.org/tidalzones BOOKS and REFERENCES: Monterey Bay Aquarium.
