Week #10

​

​

S7L4. Obtain, evaluate, and communicate information to examine the interdependence of organisms with one another and their environments.

a. Construct an explanation for the patterns of interactions observed in different ecosystems in terms of the relationships among and between organisms and abiotic components of the ecosystem. (Clarification statement: The interactions include, but are not limited to, predator-prey relationships, competition, mutualism, parasitism, and commensalism.)

b. Develop a model to describe the cycling of matter and the flow of energy among biotic and abiotic components of an ecosystem. (Clarification sc.

c. Analyze and interpret data to provide evidence for how resource availability, disease, climate, and human activity affect individual organisms, populations, communities, and ecosystems.tatement: Emphasis is on tracing movement of matter and flow of energy, not the biochemical mechanisms of photosynthesis and cellular respiration.)

Work Session - Tuesday

Anchoring Phenomenon

• Scientists predict a 33% decline in polar bear population by 2050.
• Teacher Note: This research article is the source of the prediction. It is intended for teacher background knowledge, not for student reading.

Secondary Phenomena

• Polar bears, and other arctic organisms, thrive in an environment with seemingly sparse resources.
• Polar bears actually do better on ice than vegetated land.
• Many other organisms are able to take advantage of the resources available on the arctic tundra.
• Declining sea ice is affecting polar bears’ ability to survive.
• Climate change is melting away polar bears' chance of survival.
• The Climate Time Machine (Sea Ice) shows the annual Arctic sea ice minimum since 1979.
• The Climate Time Machine shows trends in sea ice, sea level, carbon dioxide, and global temperature.
• The Climate Change Expedition shows how the various effects of climate change in different ecosystems around the world.

​

Assignments:

Create a food web showing the polar bear, 2 producers, 4 consumers, 2 decomposers, and 1 scavenger.
