This inquiry-based lesson gets students moving to simulate chemical reactions in a way that allows them to visualize, understand, and retain information about chemical reactions in the stratosphere. Students then look at scientific data and conduct research to understand trends in the data and the impact of chlorofluorocarbons (CFCs). These…

This article describes the High-Adventure Science curriculum unit "Is There Life in Space?" This free online investigation, developed by The Concord Consortium, helps students see how scientists use modern tools to locate planets around distant stars and explore the probability of finding extraterrestrial life. This innovative curriculum…

In this article, the authors provide a brief overview of the emerging field of nanoscience and why it is an important area of education. They next explain the science behind the new nanoparticulate sunscreens, describe the different elements of the unit, and reflect on some of the opportunities and challenges of teaching nanoscience at the high…

Presents a design for constructing a colorimeter as an alternative to the more expensive spectrophotometer. The materials cost less than $25.00. (PR)

The use of complex instruments for chemical analysis is becoming increasingly important. Unfortunately, because of school budgetary constraints, many students are not exposed to these methods until they reach the college level. When students do have access to sophisticated instruments, they often view them as black boxes, with little or no…

Macrolab (located at New Jersey Institute of Technology) develops devices, training models, and experiments for the scientific education of handicapped students. The construction and operation of a spectrophotometer for blind and visually impaired students are discussed. Construction details are available from authors. (JN)

Describes an apparatus (called the "Rainbow Cup") used for demonstrating the colored rings produced by constructive interference in soap films. Discusses construction of the Rainbow Cup and gives hints for its use in the classroom, especially in relation to classroom humidity. (JM)

Explained is a representation of the three categories of spectra. Discusses what a lesson on spectra should include, background information, and equipment needed. Provided is a diagram of an absorption box. (RT)

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)
