Lasting Value and High Impact
The May 2017 issue of the Journal of Chemical Education is now available online to subscribers. Topics featured in this issue include: project- and inquiry-based laboratories; measuring value and impact; research on core ideas and clickers; new twists on classic activities; understanding diffraction; acid-base chemistry; teaching informed by technology: flipped learning, biochemistry labs, and scientific computing for chemists; from the archives: chemistry helps feed the world.
Cover: Project- and Inquiry-Based Laboratories
A recent transformation in the general chemistry laboratory courses at Michigan State University has yielded a series of project-based labs focused on the scientific and engineering practices from A Framework for K–12 Science Education. One such lab investigates the chemistry behind commercially available glow sticks. Shown on the cover are reaction mixtures with four different dyes before (top) and after (bottom) the addition of hydrogen peroxide, which drives the reaction. Dyes used (from left to right) are rhodamine B, rhodamine 6G, 9,10-bis(phenylethynyl)anthracene, and 9,10-diphenylanthracene. For further details see the laboratory experiment, A Glowing Recommendation: A Project-Based Cooperative Laboratory Activity To Promote Use of the Scientific and Engineering Practices, by Justin H. Carmel, Joseph S. Ward, and Melanie M. Cooper.

From the Archives: Chemistry Helps Feed the World
Although Earth Day was celebrated in April, it's always timely to engage students with environmental chemistry. In keeping with the ACS's 2017 theme for Chemists Celebrate Earth Day, Chemistry Helps Feed the World, some ideas and suggestions for bringing environmental chemistry to students on agricultural and food chemistry, agrochemicals, and soil and water are available at ACS Axial.
