Describes an activity that uses a simulation of glacial movement to stimulate middle school students' interest in geology. (JRH)

Among the many ideas and theories in anatomy and physiology, one particular topic provides all the potential benefits of learning about the human body: the circulatory system, specifically the heart. Describes a distinctive way to study circulation and the heart that allows students to explore the basic principles of vertebrate anatomy and…

Describes fourth- to sixth-grade level activities designed to enhance science learning through the identification of science concepts and misconceptions found in the media, and by underscoring the relevance of science to everyday life. (Contains 17 references.) (ASK)

Describes an activity on biomass measurement which, in this case, is the weight of a group of living things in a given area. The earthworm activity gives students a greater understanding of ecology, practical math applications, and the scientific method. (ASK)

Desribes teaching investigations at key stages 2 and 3. Includes two activities used to develop understanding in scientific inquiry. (SAH)

This activity incorporates and utilizes a conceptual and mathematical approach toward the discovery of a relationship between force, pressure, and area for solid objects. Lists materials needed to perform the activities. (SAH)

Demonstrates whether high concentrations of carbon dioxide and water vapor can increase temperature. Lists materials needed to perform the experiment. (SAH)

Introduces activities published by the National Oceanic and Atmospheric Administration (NOAA) that can be used to explain the physical properties of a thunderstorm. Activities include cloud formation and the first step of thunderstorm development, cycle of a thunderstorm, the nature of lightning, ice in a thunderstorm, and tornado warning. Lists…

Reports on a study that investigated ways in which children's use of science journals aided their acquisition of science understanding in one kindergarten and one fourth-grade classroom. Indicates that children recontextualized their understandings of science investigations and phenomena by using three types of mental contexts reflected in their…
