<p> 7th Grade Science Unit 4: Environmental Science 2014-2015 Reporting Cluster: Interdependent Relationships in Ecosystems Topic Knowledge: Assessments: Interdependent In addition to score 3.0 performance, the student demonstrates in-depth inferences and applications Relationships in Ecosystems that go beyond the target.</p><p>Students demonstrate they have developed an understanding of: </p><p> given adequate biotic and abiotic resources and no disease or predators, populations (including humans) increase at rapid rates  The number of organisms an ecosystem can support depends on the resources available and abiotic factors  symbiotic relationships among organisms  the energy flow through an ecosystem from sunlight through organisms </p><p>Students will recognize or recall:</p><p>Specific vocabulary such as: organism, population, community, ecosystem, biotic, abiotic, predator, prey, symbiosis, producer, consumer, decomposer, herbivore, carnivore, omnivore, parasite, host, limiting factors, carrying capacity, overpopulation, niche, food chain, food web</p><p>Basic knowledge such as:  living things are interdependent in an ecosystem  the difference between biotic and abiotic factors  the number of living things in an ecosystem is dependent on resources available within the ecosystem  the characteristics of producers, consumers and decomposers  general ecosystem organization  how to interpret a food chain and food web</p><p>Student’s performance reflects insufficient progress towards foundational skills and knowledge. 7th Grade Science Unit 4: Environmental Science 2014-2015</p><p>Reporting Cluster: Independent Relationships in Ecosystems Topic Knowledge: Assessments: Natural Selection and In addition to score 3.0 performance, the student demonstrates in-depth inferences and applications Adaptations that go beyond the target.</p><p>Students demonstrate they have developed an understanding of:</p><p> species acquire many of their unique characteristics through biological adaptation which involves the selection of naturally occurring variations in populations</p><p> Biological adaptations include changes in structures, behaviors, or physiology that enhance survival and reproductive success in a particular environment</p><p>Students will recognize or recall:</p><p>Specific vocabulary such as: natural selection, adaptation, evolution, traits, mutation, genes, DNA</p><p>Basic knowledge such as:  some changes in traits are beneficial, while others cause a species to decline  evolution is small genetic changes over long periods of time  adaptation helps organisms to survive and reproduce in their environment  the differences between types of adaptations</p><p>Student’s performance reflects insufficient progress towards foundational skills and knowledge. 7th Grade Science Unit 4: Environmental Science 2014-2015</p><p>Reporting Cluster: Interdependent Relationships in Ecosystems Topic Knowledge: Assessments: Environmental Issues and 4 In addition to score 3.0 Human Impacts performance, the student demonstrates in-depth inferences and applications that go beyond the target. 3 Students demonstrate they Proficient have developed an understanding of: </p><p> the impact of industrialization and human population growth  steps individuals can take to lessen their negative impact on the environment  scientific evidence surrounding global climate change</p><p>2 Students will recognize or recall:</p><p>Specific vocabulary such as: pollution, conservation, extinction, endangered, deforestation, invasive species, habitat destruction, biodiversity, 7th Grade Science Unit 4: Environmental Science 2014-2015 reduce, reuse, recycle, renewable, non-renewable, biodegradable, conservation, global climate change</p><p>Basic knowledge such as:  human behaviors impact the environment in both negative and positive ways (3 R’s)  resources are finite</p><p>1 Student’s performance reflects insufficient progress towards foundational skills and knowledge.</p><p>Suggested Instructional Resources 7th Grade Science Unit 4: Environmental Science 2014-2015 Sample Learner
