X1013070084-00007-01991</DOCNO> Grade Level 7 GRADE LEVEL 7 Life Science (CS 3) Cell Biology Students will be able to: Distinguish between living and non-living things Explain how food and oxygen are used by the body for energy, growth and maintenance Identify and cite the need for important chemical substances found within certain foods Investigate the effect of external factors on cell chemistry (e.g. effect of heat on enzyme activity) Observe the structure and variety of cells using a microscope Define sexual and asexual methods of reproduction and give examples of organisms which reproduce by each method Observe the structure, behavior, and methods of reproduction in several types of organisms (e.g. budding in hydra, cell division in amoebae) Cite the common elements found in all cells, describe the specialized structures in certain types of cells and relate them to the function of the cells Illustrate the structure, function, and interrelationships of the parts of a cell (e.g. design, construct, and explain a model of a cell) Explain the life processes of a cell (e.g. respiration, photosynthesis, osmosis, diffusion) Compare activities of specialized cells to parts of other known systems (e.g. compare the cells of the human body to the specialized jobs done in an industrial factory) Genetics/Evolution Students will be able to: Explain how characteristics depend on genes Interpret simple genetic crosses and predict/explain patterns that emerge Recognize genetic variation by collecting and examining data (e.g. measure a physical attribute of an organism, record and graph the data, and explain the results using genetic theory) Explain how domestication influences evolution (e.g. research one or more varieties of dogs, horses, tomatoes, or trees) Identify and examine recorded fossil evidence of species that existed in the region Explain the reasons for selective breeding in plants and animals Describe how adaptations enable survival of a species and creation of new species over time Classification Students will be able to: Create and use a dichotomous key to categorize and/or identify living things Recognize and explain biological scientific names Name and describe the five kingdoms of living things Ecology Students will be able to: Explore the adaptive relationships of animals and plants to their habitats (e.g. life in a pine cone, effects of pollution on different species) Research and report on ways in which various organisms have adapted over time to their environment (e.g. desert organisms have adapted in ability to conserve water) Give several examples of competition for resources among two or more species Describe and give several examples of predator/prey relationships and use the information to create food chains and webs in several different types of ecosystems Describe symbiosis and cite several examples of symbiotic relationships Conduct an investigation which demonstrates the effect of one or more environmental factors on the viability of a plant or animal (e.g. set up ecosystem, observe and keep records of physical factors and effects on living things) Design an investigation that documents and gives possible explanation for changes within a small ecosystem (e.g. observe a small plot of land periodically over a span of time) Create a food web and explain matter and energy transfers which occur within the web Diagram and explain the cycling of materials in the environment, including both physical and biotic factors (e.g. water, oxygen, nitrogen cycles) Microbes Students will be able to: Identify and describe the characteristics and behaviors of these organisms Identify and describe the structure and function of the structures of these organisms Culture, maintain, observe, and record observations of selected protists (e.g. diatoms, Euglena) Observe the structure, behavior, and methods of reproduction of these organisms Discuss the ecological role, historically and currently, of Protists Research one or more communicable diseases and report on the current status of the disease in various areas of the world.
