7th Grade/Science Unit: Biology Concept: Ecosystems Generalizations TEKS: 7.10 The student knows that different environments support different organisms. The student knows that there is a relationship between organisms and the environment 7.10A Observe and describe how different environments, including microhabitats in schoolyards and biomes, support different varieties of organisms CCA, DCA, Benchmark , TAKS 8 Define habitat/microhabitat and biome Distinguish different biomes by their plants, animals and climate factors Identify characteristics of plants and animals that help them survive in different biomes Classify characteristics of biomes by climate factors affected by latitude MISCONCEPTIONS: Students may think that an organism can live in any biome or habitat Student Expectation: Formal Assessment: Clarification: Notes to Teacher: NOTES: Students may need to review components of ecosystems as biotic or abiotic Students may need to review producer, consumer or decomposer Taiga, boreal, and coniferous forest are all the same thing. List of Books for resources Key Academic Vocabulary: Niche habitat Abiotic Vertical Alignment: microhabitat biome 6th Grade 6.12E Describe biotic and abiotic parts of an ecosystem in which organisms interact 6.12F Diagram the levels of organization within an ecosystem including organism, population, community, and ecosystem Interdependence diversity Before After climate Biotic 8th grade 8.11A. Describe producer/consumer, predator prey and parasite/host relationships as they occur in food webs I marine, freshwater and terrestrial ecosystems 8.11B. Investigate how organisms and populations in an ecosystem depend on and may compete for biotic and abiotic factors such as quantity of light, water range of temperatures or soil composition Page 1 7th Grade/Science Core Instruction: Engage UNIVERSAL GENERALIZATION: Things exist under specific conditions Quick walk outside identifying biotic and abiotic factors in a T chart Explore School yard safari activity Biome Summaries with Student page Biomes Webquest Explain Students will need to explain their explore activity Elaborate Texas Eco-regions comparison – computer Teacher talk/whole class discussion of school yard safari focusing on the abiotic factors that might influence different populations in the microhabitats Projects: choose from the following Biome Project Travel Brochure Biome in a Box How Much Rain it that?
