Comment on Greenhouse Effect in the Classroom: A Project- and Laboratory-Based Curriculum
No full textI wonder whether the heat lamp directly heats the CO2 gas in the near-infrared to a significant effect. A more rigorous demonstration would be to heat the bottoms of the fish tanks with laboratory hot plates, being certain that they are drawing the same current.
The Dust Bowl
No full textIn the relatively wet years from the 1880s into the 1920s, new agricultural technologies took hold and farmers sowed the Great Plains in wheat, corn, and other crops, grazed cattle, and reaped tremendous rewards. In the 1930s, drought coupled with agricultural practices unsuited to the open plains turned the region into a giant dust bowl, forcing large numbers of the population to give up their lives on the plains and to move west. This unit offers readings, images, and activities that explore the connections between place, weather and culture as they relate to the Dust Bowl. One activity uses the Palmer Drought Severity Index data to look at drought conditions in the southwest corner of Kansas over the course of the 20th century. An activity using Geographic Information Systems (GIS) software analyzes census data from 1930 to give students an idea of how much of the available land in the Dust Bowl region was farmed. Educational levels: High school
Extra-Credit Problems in Space Science
No full textThese activities comprise a series of 20 practical math applications in space science. Students looking for additional challenges in math and physical science can use these as extra credit. The problems are authentic glimpses of modern engineering issues that arise in designing satellites to work in space. Each word problem has background information providing insight into the basic phenomena of the sun-Earth system, specifically space weather. The one-page assignments are accompanied by one-page teachers guides with answer keys. Educational levels: Middle school, High school
Deep Time: The Geologic Time Scale
No full textThis page examines the issues involved in teaching students about the geologic time scale. There are suggestions for tackling troublesome issues in class as well as activities that can be used to clarify how geoscientists look at deep time. Five main concepts with which students struggle when thinking about Deep Time are addressed here: imagining or comprehending big numbers; the difference between relative and numerical age; the concept of "timescales"; the ways we know about the age of the Earth and other materials; and resolving perceived issues with religious beliefs. Educational levels: Intermediate elementary, Middle school, High school
PBL in Complex Terrain - Part 1
No full textThis is part 1 of a 2-part Webcast based on a presentation by Dr. David Whiteman on August 11, 2004 in Boulder, CO. Dr. Whiteman presents conceptual and practical information regarding winds in the planetary boundary layer in complex terrain. Part 1 topics include diurnal wind systems, mountain-plain wind systems, and slope wind systems. Educational levels: Graduate or professional
