Describes a project designed to teach students how to measure ground-level ozone and determine ozone concentrations. Enables students to research the effects of ozone exposure and discuss ways to clean up the problem. Includes an activity based on the oxidation capability of ozone. (JRH)

Presents activities that help students distinguish between the beneficial layer of stratospheric ozone and the dangerous ground-level or tropospheric ozone, understand the chemical processes of ozone breakdown in the stratosphere, find the sources of ground-level ozone, and explore the differences in the patterns of ozone concentration over the…

Describes the use of analogies to explain scientific concepts. Presents the teaching-with-analogies model. (JRH)

Presents a lesson, Scientific Literacy Is a Lifetime Skill, that provides thought and discussion on science as an aspect of everyday life. Uses concept mapping to help students explore from their perspective the relationship between formal science education and real-world situations. (JRH)

Presents an activity that involves making peanut butter in the laboratory as a way to teach students the chemistry concepts of emulsification, solubility, and formulation. Enables students to realize that they can actually create or modify the physical and sensory characteristics of peanut butter and taste the differences in their work. (JRH)

Describes a project where students build a motorized car that can perform well in two distinctly different competitions: traveling 20 meters in the shortest time and pulling a 500-gram mass the farthest distance in 20 seconds. Enables students to apply physics principles to a real problem and to discover the importance of teamwork on large…

Presents an activity that involves using sponge seedlings to demonstrate the germination process without the usual waiting period. Discusses epigeous versus hypogeous germination, and cotyledon number and biodiversity. (JRH)

Describes methods to redevelop lab activities for use in schools with limited resources for proper facilities and equipment. Discusses take-home labs, paper-and-pencil labs, and lab station activities. (JRH)

Discusses the use of high school students to present physics demonstrations to first graders. (MKR)

Presents information about making a scale model of Jupiter and its system of moons. (MKR)

Discusses a program in which students complete surveys identifying home energy and water use and its impact on the environment. Survey results are entered into computers lent to the school by a sponsoring utility company. Includes sample activities. (MKR)
