We can make these stories and their lessons accessible to students with help from the EcoTipping Points Project, which has…

Explains the historical perspective of textbook selection and adoption. Discusses factors affecting textbook publishing. (YDS)

Describes a number of demonstrations for physics that employ techniques of the martial arts to illustrate Newton's second law of motion. Demonstrations focus on the breaking of wooden boards using weights. (DDR)

Presents investigations in which students are provided with a series of four mystery items related to cicadas. Observations and a class discussion follow each item. Contains basic information on doing experiments with live cicadas, specific assessment strategies for this activity, and facts about cicadas. (DDR)

Presents a week-long unit of study that covers the concepts of acid base chemistry and involves students in a context in which that information is relevant. In this activity, students build a model swimming pool and must maintain the chemistry of their pool at safe levels. (DDR)

Presents activities that use marine organisms with plant-like appearances to help students build classification skills and illustrate some of the less obvious differences between plants and animals. Compares mechanisms by which sessile plants and animals deal with common problems such as obtaining energy, defending themselves, successfully…

Presents activities that use antifreeze to introduce students to concepts such as density, specific gravity, solutions, and freezing and boiling points. (JRH)

Describes the use of carbide lights as an excellent mechanism for introducing or reviewing many basic chemistry concepts including elements and compounds, endothermic and exothermic reactions, physical and chemical changes, and balancing chemical equations. (JRH)

Explains how watching video clips of Richard Feynman helped students change their ideas regarding science, scientists, and society. (PR)
