Instruction

1

Ecosystem Interactions and Energy

Students use mathematical and computer models to determine the factors that affect the size and diversity of populations in ecosystems, including the availability of resources and interactions between organisms.

2

History of Earth’s Atmosphere: Photosynthesis and Respiration

Students make a model that links photosynthesis and respiration in organisms to cycles of energy and matter in the Earth system. They gather evidence about the linked history of Earth’s biosphere and atmosphere.

3

Evidence of Evolution

Students develop a model about how rock layers record evidence of evolution as fossils. Building on their learning from previous grades, they focus on effectively communicating this evidence and relate it to principles of natural selection.

4

Inheritance of traits

Students develop explanations about the specific mechanisms that enable parents to pass traits on to their offspring. They make claims about which processes give rise to variation in DNA codes and calculate the probability that offspring will inherit traits from their parents.

5

Structure, Function, and Growth (from cells to organisms)

Students use models to create explanations of how cells use DNA to construct proteins, build biomass, reproduce, and create complex multicellular organisms. They investigate how these organisms maintain stability.

6

Ecosystem Stability & the Response to Climate Change

Students use computer models to investigate how Earth’s systems respond to changes, including climate change. They make specific forecasts and design solutions to mitigate the impacts of these changes on the biosphere.
