Many students probably know something about space from playing computer games or watching movies and TV shows. Teachers can expose them to the real thing by launching their experiments into near space on a weather balloon. This article describes how to use high-altitude ballooning (HAB) as a culminating project to a chemistry unit on experimental…

The number of students majoring in science, technology, engineering, and math (STEM) is declining due in part to a lack of student interest (Fairweather 2008; NRC 2012; PCAST 2010). One reason may be the difference between how science is done in school and how it is done in the field (Osborne, Simon, and Collins 2003). An interdisciplinary…

A floating bowling ball? No way! There is no better way to get students' attention and reinforce the need for conceptual understanding than with a discrepant event like this. Density is a central concept in chemistry and physical science from middle school to college. But often, particularly at the high school and college levels, we think students…

Describes a teaching technique where students are to describe in detail, identify the unusual aspects of, and then provide an explanation of puzzling events or situations" in terms of previous experience and known scientific principles. Illustrated with examples, mostly chemical. (AL)

Described is a program in which students learn about spectroscopy and instrumentation to solve a chemical forensic mystery. Infrared and nuclear magnetic resonance (NMR) spectroscopy, refractometry, and chromatographic techniques were used. An example of a mystery case is included. (KR)

Described is a project designed to give students an understanding of the environmental implications of current energy practices and a chance to participate in a project that may have a measurable impact on environmental quality. Suggestions for the integration of this project into high school science classes are provided. (CW)

Provided are examples of science/society scenarios for biology, chemistry, and physics classes, as well as those of an interdisciplinary nature. These scenarios present some social or ethical problems related to the discipline and pose questions for student discussions. (Includes description of a project involved in developing/piloting such…
