The development of conceptual knowledge about the earth among 60 elementary school students in grades 1, 3, and 5 was studied through questions about its shape. In the process of knowledge acquisition, children appear to modify their initial models to make them more consistent with the culturally accepted model. (SLD)

Author describes how 22 first-year high school students became politically active concerning coastal-zone management and wetlands protection. Students translated regulations of the Maine Department of Environmental Protection into plain English. Students wrote their opinions in a concise manner and appeared at a board meeting to influence its…

Describes an approach to introductory geology that requires students to go into the field to make observations, collect and analyze data, synthesize those data, and hypothesize about inferred geologic relationships. The product of these laboratories is a paper that requires students to test their hypothesis using specific examples from the data.…

Author describes an individual research project involving digital modeling of graded river profiles as part of a sophomore-level geomorphology class. The three-week project gives students the opportunity to choose research topics, design experiments to test ideas, interpret results, and write a research report. (PR)

Describes the creation of a glacial park on a university campus. Suggests that the park is a useful instructional resource that helps students relate classroom material to outdoor phenomena by visualizing and identifying glacial landforms, recognizing their spatial relationships, and understanding how glacial features originated. Offers advice for…

Presents two activities for introducing the topic of carbon dioxide: (1) Investigating Some Properties of Carbon Dioxide and (2) Building a Carbon Dioxide Generator. (PR)
