Morgan Hunt EDUC 460 Exploring Ecology and Conservation Extinction and Conservation Each student should have some prior knowledge about species that no longer exist currently. Each student should have prior knowledge of the terms extinction, endangered and how these events affect the environment. Each student should have some prior knowledge about species interactions (predator and prey relationship, herbivore, carnivore, etc.) Each student should have some prior knowledge about examples of species interactions (Types of predators, prey, etc.) NGSS Standard: HS-LS2-6: “Evaluate the claims, evidence, and reasoning that the complex interactions in ecosystems maintain relatively consistent numbers and types of organisms in stable conditions, but changing conditions may result in a new ecosystem” Colorado Standard: 2.2 High School Life Science “The size and persistence of populations depend on their interactions with each other and the abiotic factors in an ecosystem.” “How do keystone species maintain balance in ecosystems?” Learning objectives (SWBAT): Demonstrate understanding of the consequences of species extinction on an ecosystem through creating a conservation plan. Demonstrate understanding of conservation through completing the web quest and creating a conservation plan. Demonstrate real world knowledge of a practical conservation plan.

Teacher Activity Have PowerPoint with KWL about extinction and habitat loss on the screen when students walk in. Ask students as a whole what they know about conservation. Ask students as a group what they know about species extinction and what causes it. Explore Watch video, take notes and write down any questions Play video Explain Discussion What is their reaction to the video? Ask students if they have heard about these animals going extinct? How will these species going extinct affect the environment? What steps can be taken to prevent species extinction? Elaborate Complete web quest with a partner Do research as directed Compile information about their ideas for a conservation plan Begin creating conservation plan (This will be finished later if not complete today.) Evaluate KWL What did they learn? What do they want to learn more about? Get students in groups of two by having them group up with another student with the same birthday month. Explain what a web quest is and the role they will be taking. Tell students to save their work and that they can continue tomorrow. Ask students to fill in the KWL chart with that they learned today and what they would like to learn more of. Assessment Formative: KWL written in their scientific notebook before and after class. Have student turn their notebooks in at the end of class. Summative: Conservation plan once completed or worksheet. Anticipated misconceptions/alternative conception Species have always gone extinct so we do not need to worry about a few animals or plants disappearing. Losing a species does not affect humans. Evolution will replace any missing species. All species have been discovered There is nothing I can do to protect the Earth’s biodiversity Accommodations/modifications Some students may not be able to complete the conservation plan so here is an alternative activity about species interactions that could cause extinctions if not resolved. Vocabulary Community: an area that different species occupy at the same time Extinction: An event in which the last members of a lineage or species die. A single species may go extinct when all members of that species die, or an entire lineage may go extinct when all the species that make it up go extinct. Fossils: Any trace of a living creature (body, part of body, burrow, footprint, etc.) preserved over geologic time Habitat: Place and condition in which an organism normally lives. Mass Extinction: Event in which many different lineages go extinct around the same time. Mass extinctions involved higher rates of extinction than the usual rate of background extinction that is going on all the time Species: the largest group of animals that can reproduce and have babies that can reproduce Species Competition: Two animals or species need the same resource (food, water, room to live) but only one gets it Collect all the pebbles necessary and complete the following questions. As of right now you are going to pretend that you are a researcher in the mountains watching animals eat dinner in the same area. Some animals eat more fish than others and some animals eat not fish. When too many predator species come into the area they compete with one another for the fish. The chart explains which predator gets to eat and in what order. Pebbles Species What they eat 30 black Fish 2 green Deer Consumed by other species only for this activity Grass and other plants 5 red Big Horn Sheep Grass and other plants 3 white Mountain Lion 3 blue Bear 5 yellow Wolves 10 fish each Mountain Lions eat first 10 Fish each Bears eat second 5 Fish each Wolves eat last 1.) The area you are watching has a stream with 25 fish nearby. 2 deer, 2 big horn sheep and 5 wolves enter the area. (Show this with your pebbles) How many fish are left in the steam? How does this affect the habitat? (Explain using full sentences and the vocabulary given) 2.) The area you are watching has a stream with 25 fish nearby. 2 deer, 2 big horn sheep, 2 wolves and a mountain lion enter the area. (Show this with your pebbles) How many fish are left in the steam? How does this affect the habitat? (Explain using full sentences and the vocabulary given) 3.) The area you are watching has a stream with 25 fish nearby. 2 deer, 2 big horn sheep, 3 bears enter the area. (Show this with your pebbles) How many fish are left in the steam? How does this affect the habitat? Is it a good thing or bad thing to have that many predators in the same place? (Explain using full sentences and the vocabulary given) 4.) The area you are watching has a stream with 30 fish nearby. 2 deer, 2 big horn sheep, 2 bears, 1 mountain lion and 1 wolf enter the area. (Show this with your pebbles) How many fish are left in the steam? How does this affect the habitat? (Explain using full sentences and the vocabulary given) 5.) Extra Credit: The area you are watching has a stream with 30 fish nearby. The bears in the area want to start eating plants to have a balanced meal. They can eat both fish and plants in one day. The area you are watching has 25 plants nearby to eat. Deer eat 5 plants a day, big horn sheep eat 5 plants a day and bears eat 10 plants a day. If 2 deer, 2 big horn sheep, 1 mountain lion and 2 bear are in the same area how many plants are left over? How many fish are left over? How does this affect the habitat? (Explain using full sentences and the vocabulary given)
