Discusses some misconceptions relating to location and to the earth's hydrosphere, atmosphere, and lithosphere. Provides correction and explanation of various phenomena. Includes ocean names and sizes, sea level, coriolis effect, greenhouse effect, lightning, magma, and mass wasting. Suggests that myths can be dispelled by exposure combined with…

An activity that introduces the concept of chaos to students is presented. Smoke rising from burning incense is used to represent changes in atmospheric flow. The lab, involving fluid dynamics, avoids mathematical models to highlight deterministic chaos within nature itself. Reproducible pages are provided. (KR)

Presents a reproducible page for students dealing with the following topics: plate tectonics, magma, crust, and earthquakes. Provides a plate tectonics activity that uses cardboard and clay. (PR)

Presents two methods to teach the phases of the Moon: (1) students use a Styrofoam ball (Moon), light bulb (Sun), and one's own head (Earth) to model the Earth-Moon-Sun system; (2) students use their hands to represent the location of the Sun, Earth, and Moon during a teacher controlled "Moon Dance." (MVL)

Describes an activity that allows students to develop their own animated models that depict the orbits of the earth and the moon. (ZWH)

Provides a graphing exercise designed to help students understand the coevolution of the physical environment and the biosphere during the last four billion years of Earth's history. The ideas are based upon the Gaia theory, which is the belief that the Earth is a self-regulating network of interdependent physical and biological systems. (ZWH)

Presents the philosophical, methodological, and conceptual contributions of earth science to the biology curriculum. Explores how the curriculum can build on these contributions to achieve greater relevance for students as a basis for decision making. Gives examples of computer networks that accomplish that goal. (11 references) (MDH)

Describes an exercise where a team of students constructs a scale map of objects located on their laboratory tabletop. Another group then tries to reorient the objects to fit the groups map. This leads to a discussion concerning the aspects of good and bad maps. (PR)

Describes a two-week summer experience for teachers and students on a dig in Colorado looking for fossil records of the plants and animals in the area. (DDR)

Finds variable coverage of Earth Science topics in the United Kingdom among General Certificate of Secondary Education (GCSE) double-award science syllabuses and examination papers. Concludes that the levels of error in the examination papers were high and that Earth Science questions showed lower levels of demand and higher levels of recall than…

Critiques the scientific merit of a claim against evolution that is based on a calculation of the level of salt in the oceans. (WRM)

Makes comparisons between the Earth and other planets to suggest a possible vehicle for predicting the effects of human-made or natural disasters on our Earth. Also included are brief discussions of the following topics: (1) the atmosphere and greenhouse effect; (2) alterations of the biosphere; (3) climate and climatic change; (4) the water…

Provides rich background information about unique High Plains ecosystems. Focuses on water, plant, animal, and energy resources. Describes hands-on activities related to ground water movement and energy resources. Contains 18 references. (DDR)

Presents activities for elementary and middle school students on the sun and the Earth-sun relationship. Studies the structure of the sun with activities that include Shadow Play, Reflective Solar Cooker, Equatorial Sundial, and Tracing Images. (YDS)

Uses the PowerPoint program instead of paper in student projects. Describes the background and procedure for project implementation. Presents students' written comments on the project and discusses the challenges of incorporating multimedia into the earth science curriculum. (YDS)
