Description

In this classroom activity, students analyze visualizations and graphs that show the annual cycle of plant growth and decline. They explore patterns of annual change for the globe and several regions in each hemisphere that have different land cover and will match graphs that show annual green-up and green-down patterns with a specific land cover type.

HS-LS2-5 Develop a model to illustrate the role of photosynthesis and cellular respiration in the cycling of carbon among the biosphere, atmosphere, hydrosphere, and geosphere.

HS-ESS2-6 Develop a quantitative model to describe the cycling of carbon among the hydrosphere, atmosphere, geosphere, and biosphere.

Compare and contrast various types of data sets (e.g., self-generated, archival) to examine consistency of measurements and observations.

Ask questions to determine relationships, including quantitative relationships, between independent and dependent variables.

Make a quantitative and/or qualitative claim regarding the relationship between dependent and independent variables.

Construct, use, and/or present an oral and written argument or counter-arguments based on data and evidence.

Develop and/or use a model (including mathematical and computational) to generate data to support explanations, predict phenomena, analyze systems, and/or solve problems.

Compare, integrate and evaluate sources of information presented in different media or formats (e.g., visually, quantitatively) as well as in words in order to address a scientific question or solve a problem.

Make directional hypotheses that specify what happens to a dependent variable when an independent variable is manipulated.

Although energy cannot be destroyed, it can be converted to less useful forms—for example, to thermal energy in the surrounding environment.

The foundation for Earth’s global climate systems is the electromagnetic radiation from the sun, as well as its reflection, absorption, storage, and redistribution among the atmosphere, ocean, and land systems, and this energy’s re-radiation into space.

Gradual atmospheric changes were due to plants and other organisms that captured carbon dioxide and released oxygen.

Empirical evidence is required to differentiate between cause and correlation and make claims about specific causes and effects.

Different patterns may be observed at each of the scales at which a system is studied and can provide evidence for causality in explanations of phenomena.

Much of science deals with constructing explanations of how things change and how they remain stable.

Cause and effect relationships can be suggested and predicted for complex natural and human designed systems by examining what is known about smaller scale mechanisms within the system.

Energy drives the cycling of matter within and between systems.

Empirical evidence is needed to identify patterns.

Changes in systems may have various causes that may not have equal effects.
