1 Fifth Grade Unit Two: Ecosystems p. 1 Unit Overview Pacing 2 nd Quarter/ 8 weeks The purpose of this unit is to build and understanding of Activities: Unit B Lessons 1-6 Grade level Science Books: Wildfire, The Eagles are Back! Antarctica. Interactions in an ecosystem B4 Read What is an ecosystem? pg. B6-13 Quick Lab- Changing the environment-pg. B13 Activity Resources pp Resources, pp Vocabulary Cards Transparency B1. Activate prior knowledge and discuss how they provide for the needs of plants and animals. What is an ecosystem? P B6-B13. What is a Prairie Ecosystem Like? B8-B11. Quick Lab p. B13- Research an animal and how the change their environment Read and discuss this section. Use the red questions to give a purpose for reading. Develop vocabulary: population, community, ecology, ecosystem, abiotic factor, habitat, niche Explore Activity: pb5-what do Living Things need to Survive? Resource pp Active prior knowledge focusing on interdependence. Why do animals depend on plants? Do plants depend on animals? What is a food chain? P B18 Resource p 91, Vocabulary: food chain, food web, herbivore, carnivore, predator, prey, and scavenger. How are populations connected? B 22

2 Fifth Grade Unit Two: Ecosystems p. 2 The purpose of this unit is to build and understanding of Activities continued: Objectives continued: 1.05 Determine the interaction of organisms within an ecosystem Explain and evaluate some ways that humans affect ecosystems. Habitat reduction due to development. Pollutants. Increased nutrients Determine how materials are recycled in nature. Interactions among living things-what is a food change? Pg. B18 Quick Lab- Getting Food: classify producers and consumers. How Populations Survive pg. B Resources, pp Transparency B2. Transparency 8. School to Home Activities, pp How Populations Survive pg. B30- How do food webs affect you? Explore Activity- p. B17 How Do Populations interact? Alternative Explore (Activity Resource p. 54). Quick Lab p. B19 Take a walk around the school and have the students makes a list of living things they see. Connect these animals in a food chain. Ask students to find out how people make compost in home gardens and for commercial use. Research various containers and ways to speed up the decomposition. Activate prior knowledge of students about how organisms interact in their environment. What determines what trees, animals, etc. will survive in an environment? What controls the growth of population? PB34. What happens when habitats are changed? How do people change the environment? p 97 How populations survive p B32. Vocabulary: threatened, endangered species, extinct. Explore Activity p B33 What controls the growth of population?

How ecosystems change p B 78 Earth s Atmosphere pg. C60 Quick Lab: Playground Space. P B35. Students discuss what they know about the water and carbon cycles. When you inhale, what is your body getting? Where do you get it? When you exhale, what does your body give off? Cycles of life p B50-B55 Water cycle, carbon cycle and nitrogen cycle. Earth s Atmosphere p B 60. How are trees recycled? P B56. Vocabulary: evaporation, condensation, and precipitation. Explore Activity p. B49- Students experiment with the water cycle. Quick Lab p 57- Students create and understanding of compost and what it contains. Have students discuss what they know about different types of soil. Compare different types of soil: beach, potting soil, and playground.
