ESS2.D: Weather and climate

In this audio slideshow, an ecologist from the University of Florida describes the radiocarbon dating technique that scientists use to determine the amount of carbon within the permafrost of the Arctic tundra.

This activity from NOAA Earth System Research Laboratory introduces students to the scientific understanding of the greenhouse effect and the carbon cycle. The activity leads them through several interactive tasks to investigate recent trends in atmospheric carbon dioxide.

Students will understand the various ways soil is formed, soil formation factors, and the amount of time necessary to build or rebuild soils.

his activity uses a qualitative nitrate test to observe results of some conversions and transformations in the nitrogen cycle.

The lessons in this Soils Overview Unit provide students with a basic understanding of the fundamentals of soil science through the integration of disciplinary core ideas, science and engineering practices, and crosscutting concepts. The unit includes six sections, each containing learning objectives, background information, student information, selected resources, and ties to the NGSS standards
