This lesson was developed to give participants an understanding of Earth's water cycle. In this one-hour long activity, students participate in a webquest to learn about the water cycle, and then build a mini-model of the water cycle to observe how... (View More)

Water is essential to Earth's living system, the biosphere. In this lesson, students determine the types of living things within an outdoor study site, use a taxonomic key to determine the predominant land cover type of their site, then predict the... (View More)

Students begin by determining dew point using an aluminum can, stirring rod, ice and thermometer. Air temperature is also measured and recorded. Students then use those two data in conjunction with the Lifting Condensation Level approximation, to... (View More)

Students will design, build and then test a rain gauge to measure precipitation. By sharing their results, they will recognize the need for standardization and precision in scientific tools. All background information, student worksheets and... (View More)

Unit three of the "Carbon Connections: The Carbon Cycle and the Science of Climate" curriculum examines the role of carbon and the carbon cycle in future climate. Students discover how scientists determine Earth's average temperature and the role of... (View More)

Unit two of the "Carbon Connections: The Carbon Cycle and the Science of Climate" curriculum examines the role of carbon and the carbon cycle in current climate. Students discover how carbon in Earth's system is monitored and also investigate the... (View More)

Unit one of the "Carbon Connections: The Carbon Cycle and the Science of Climate" curriculum introduces the role of carbon (as carbon dioxide) as an atmospheric indicator. Students examine the impact of geologic and climatic history on current... (View More)

This textbook chapter introduces the buffalo as a keystone species, and describes the environmental impacts of its near extinction, including today’s predominance of non-native species in the Great Plains. Human activities that contribute to... (View More)

This model demonstrates convection currents and uses water, food coloring, a cup of very hot water and a votive candle as heat sources. Movie clips of demonstration setup and convection in action are provided. This activity is supported by a... (View More)

In this kinesthetic activity, students take on roles of either photons or gas molecules. Photons signal a change from visible light to infrared with a piece of folded construction paper, simulating absorption by the Earth's surface and reradiation... (View More)
