Presents a simple activity to determine the layout of the magnetic poles in a flat rubber or plastic refrigerator magnet. (JRH)

Presents a participation activity for students of all ages that stimulates the processes that occur in the build-up of a laser pulse. Exposes students to the concepts of coherence, monochromaticity, stimulated emission, pulse build-up from background fluctuations, and the properties that dictate the shape of a typical laser pulse. (JRH)

Presents a sample HyperQuiz, a strictly-for-fun, genius trapping contest for occasions when the syllabus and coverage do not bear down too severely. Promotes collaboration between students, library research, and development of scientific thinking skills. (JRH)

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 an activity that allows students to use a rectifier circuit to convert alternating current into direct current. Also informs teachers of how to obtain most of the equipment needed for free. (ZWH)

Students are able to experience cellular respiration in action and become more informed about the environment by creating compost. This article describes an activity that brings a natural process into the classroom. (ZWH)

Provides a simple recipe for "slime" as well as some ideas for using this substance with young children. (DDR)

Presents a game called the Meiosis Shuffle that helps students simulate the process of meiosis in which homologous cards representing chromosomes pair up, line up, and split apart. Students respond well to the simulation and are better able to conceptualize what chromosomes do and how independent assortment causes genetic variation. (CCM)

Describes how a classroom observation of apples led to the development of a science project. Discusses the correlation between the greenness and the acidity of apples. Finds that the greener the apple, the lower its pH, and thus the more acidic and less sweet it tastes. (Author/CCM)

Describes The Habitat Puzzler, an activity that bridges the gap between education and entertainment. Illustrates the concepts of native plants and wildlife through five interpretive stations. (CCM)

Introduces the science activity project, "Find Out Why", which targets eight- and nine-year-old children and their parents. Includes two sample activities. (YDS)

Lists instructions for creating a rubric and provides a scenario for a future creature assignment with the rubric. (YDS)

Describes the use of concept-centered minilabs in physics instruction. Finds this method successful in several courses taught by different instructors at Rutgers University. (CCM)

Studies the optimum launch angle for maximizing the long jump from a kinematical point of view. (CCM)

Analyzes the motion of a charged point particle started from rest near the center of a charged circular ring. (CCM)
