Pitt County Schools 302045 Honors Health Science Biology Instructional Guide – 2007-08 DIFFERENTIATION OF BIOLOGY INSTRUCTION: Standard Biology will focus on research tasks and class projects, preferably with a small group approach. A formal research paper is not an expectation within this class, however students are expected to complete formal laboratory write-ups and essays. Honors Biology will extend the focus of the Standard Biology concepts to include in-depth independent research, projects, formal laboratory write-ups, and research papers. Students will also be expected to read, discuss, and critically analyze current scientific research literature. Honors Biology students will spend research time outside of the classroom in order to adequately meet these expectations. Goal 1: Learner will develop abilities necessary to do and understand scientific inquiry. Goal 1 addresses scientific investigation. These objectives are an integral part of each of the other goals. Students must be given the opportunity to design and conduct their own investigations in a safe laboratory. The students should use questions and models to formulate the relationship identified in their investigations and then report and share those findings with others.

RECOMMENDED AND SUGGESTED CLASSROOM ACTIVITIES RECOMMENDED INTERNET ACTIVITIES & RESOURCES Inquiry Support Activity: Campus Field Study – Biodiversity of plants and animals in soil & or water SAS Interactivity Stream Ecology Suggested Activities & Labs: Duckweed (PCS Lab #13, p. 56) CH 4 CH 3 What factors influence biodiversity? How is carrying capacity different for two organisms living in the same environment? Techniques of field ecology 22 CH 5 Instructional Content: Students should be able to identify and describe symbiotic relationships Mutualism Commensalism Parasitism Abiotic and biotic factors Carrying capacity 5.02 Analyze the flow of energy and the cycling of matter in the ecosystem. Determining Population Size (Glencoe, p. 108) Investigating the growth of a population of bacteria (PH p. 133) Students should be able to identify and predict Suggested Projects: Biome Research – create a patterns in Predator /prey relationships. newspaper/ travel brochure/ website/ power Use field ecology techniques such as point presentation. Use sampling and quadrant studies to determine climate data to create species diversity and changes over time. climatograms. Explain how abiotic and biotic factors are related to one another and their importance in Essential Health Science Connection: ecosystems. Relate effects of air pollution to the Analyze how limiting factors influence physiological systems of carrying capacity (e.g. food availability, the body. competition, harsh winter). Interpret population growth graphs. Examine Lichen as biological indicator of air pollution. Essential Questions: What roles do cellular respiration and photosynthesis play in the carbon cycle? Suggested Activities & Labs: Biogeochemical Cycles – posters; peer presentations; work in pairs with emphasis on carbon cycle. How do trophic levels determine how energy is transferred through ecosystems? How are trophic levels related to food webs? What are the effects of biomagnification with respects to the food chain? 23 Mystery of the Owl Pellet (see resource book) Inquiry Support Activity: Food Chains and CH 3 SAS Interactivity: Carbon Cycle Relationship of the carbon cycle to photosynthesis and respiration Trophic levels- direction and efficiency of energy transfer Instructional Content: Investigate the carbon cycle as it relates to photosynthesis and respiration. Analyze food chains, food webs, and energy pyramids for direction and efficiency of energy transfer. Extended Content: Nitrogen cycle, Phosphorus cycle 5.03 Assess human population and its impact on local ecosystems and global environments: Essential Questions: What factors influence the J and S-shaped population curves? How are they significant? Biological Magnification Suggested Projects: Energy Flow in Ecosystems (Food Webs/Chains) design and construct a food web; presentation to class; individual (can be done as poster, or computer generated) Essential Health Science Connection: Relate biomagnification to the incidence of cancer. Inquiry Support Activity: Environmental Factors that Affect the Hatching of Brine Shrimp How do human activities affect ecosystems? Historic and potential changes in population Factors associated with those changes. Instructional Content: Instruction should include: Analyze human population growth graphs (historical and potential changes) .(See 5.01) Factors influencing birth rates and death rates. Effects of population size, density and resource use on the environment. Discussion of human impact on local ecosystems: Acid rain Habitat destruction Introduced non-native species. How changes in human population affects 24 Suggested Activities & Labs: Human Population Growth Models – research a given country; analyze demographics; develop a histogram; present findings on poster; individual. Determine Ecological Footprint (online or paper survey). Sustainable practice/stewardship activity (ex.

Climate Change. Resource use Sustainable practices/ stewardship. Discussion of factors that influence climate: greenhouse effect (relate to carbon cycle and human impact on atmospheric CO2) natural environmental processes (e.g. volcanos) Investigation of the direct and indirect impact of humans on natural resources (e.g. deforestation, pesticide use and bioaccumulation research ) Examples of sustainable practices and stewardship. project, poster display).
