View Resource Carbon Cycle Diagram

This diagram illustrates some of the most abundant stores of carbon and identifies some of the pathways in the carbon cycle along which carbon is transferred from one form to another. Long-term sinks of carbon are labelled in black; shorter-term fluxes are labelled in purple. Amounts are in billions of tons.

View Resource Dust to Dust: The Carbon Cycle

This case study examines the carbon cycle: from carbon becoming carbon dioxide, to carbohydrate, to animals, then back to carbon dioxide again. Chemistry topics like atomic structures, carbon isotopes, radiocarbon dating, beta decay, half-life and photosynthesis are explained. The case study and teaching notes may be downloaded in PDF format. The site also includes a section for instructor...

View Resource Estimating Rates of Photosynthesis

In this lab activity from the Biotechnology Alliance for Suncoast Biology Educators, students will explore photosynthesis, develop a testable hypothesis about the effect of light quality (color) on the rate of photosynthesis of Elodea, and graph measurement data from their testing. The lesson includes background information on photosynthesis, the materials needed, and the procedure.

View Resource CarbonTracker

This portal provides information about the National Oceanic and Atmospheric Administration (NOAA) Earth System Research Laboratory (ERSL) CarbonTracker, a system to keep track of carbon dioxide uptake and release at the Earth's surface over time. CarbonTracker produces model predictions of atmospheric CO2 mole fractions, to be compared with the observed atmospheric CO2 mole fractions. Materials...

View Resource When is Dinner Being Served? Predicting the Spring Phytoplankton Bloom in the Gulf of Maine

This is a student activity regarding phytoplankton blooms and their effects on the ecosystem. Students will obtain and analyze data on the variables that influence the spring phytoplankton bloom from buoy monitoring stations in the Gulf of Maine. Activity includes background information, step by step instructions, additional resources, and activity extensions.
