Know that fluctuations in population size are determined by the relative rates of birth, immigration, emigration and death. Know that concentrations of nonbiodegradable (e.g., pesticides) increase as we go up in a particular food chain (i.e., that the further we go in the direction of consumers whose food is tainted with pesticide, the more concentrated the levels of the pesticide). Understand that this process is called biological magnification. Understand how agricultural run-off and pollution entering groundwater and surface water can affect drinking water and local wildlife. Understand that a vital part of an ecosystem is the stability of its producers and decomposers. Understand the effects upon the population of a species caused by various ecological factors, particularly (a) the presence of another species with competitive feeding habits, (b) the presence (or absence) of and number of predators, (c) the abundance or scarcity of food sources. Summary of Unit Human impact on environment focusing on day to day activities. Photosynthesis and respiration will be used as a transition to cells.

How will you organize and sequence the learning activities to optimize the engagement and
achievement of ALL students?
Hook students with “Dirty Jobs” video clip (or alternative). What have you done today discussion? What is your footprint? How does your footprint affect the natural balance of the world (influence other
organisms)? Natural Balance
- invasive - pollution - deforestation
Research issues on human impact on the environment and discuss. Complete performance task.
Natural recycling/decomposition. Cellular respiration/photosynthesis to cells.
Topics 1. Habitat destruction and formation of preserved areas/endangered species.
“Global warming”
Human activity Natural disaster
2. Invasive species 3. Pollution
Land Water Air
4. Respiration/photosynthesis
Anaerobic vs. aerobic respiration Populations affect rates of respiration
Anaerobic – bacteria (sewers) – single cell prokaryotes Single cells to multi cellular organisms (get into organelles)
*Honors bio students should have an understanding of Kreb’s Cycle & Citric Acid Cycle.
