Kuntzleman, Thomas S., and Bruce W. Baldwin. “Adventures in Coaching Young Chemists.” Journal of Chemical Education 88, no. 7 (2011): 863–867. doi:10.1021/ed2002779.

Abstract: We believe that students should have opportunities—early and often—to learn about science and math activities in fun and recreational ways. As a result, we try to provide many science enrichment activities to the surrounding community. In doing so, we hope to inspire young students to become future scientists and mathematicians. Here we describe some annual science outreach events that we have hosted, share a few demonstrations and activities we have tried at these events, and discuss how we plan to connect our outreach in 2011 to the themes of the International Year of Chemistry.

Baldwin, Bruce W., Scott Hasbrouck, Jordan Smith, and Thomas S. Kuntzleman. “Classroom Activity Connections: Demonstrating Various Flame Tests Using Common Household Materials.” Journal of Chemical Education 87, no. 8 (2010): 790–792.

Abstract: In JCE Activity #67, “Flame Tests: Which Ion Causes the Color?”, Michael Sanger describes how to conduct flame tests with household items. We have used this activity in outreach settings, and have extended it in a variety of ways. For example, we have demonstrated large-scale strontium (red), copper (green), and carbon (blue) flames using only household items, and have helped children investigate the chemistry of sparklers and colored flame birthday candles.

Wilhite, David M., and Bruce W. Baldwin. “Triboluminescent Crystals from the Microwave Oven.” Journal of Chemical Education 79, no. 11 (2002): 1344.

Abstract: Anthranilic acid was acetylated in a microwave oven (1,000 W) by irradiating for one minute at full power in a 100 mL beaker fitted with a glass funnel as condenser. After cooling, yellow fluorescing crystals were often obtained; but, if not, recrystallization from 10% water–methanol yielded cubes that fluoresced brightly under 360 nm light. Crushing the crystals between two watch glasses in a darkened room demonstrated the triboluminescent effect (i.e., the production of bright blue sparks when the crystals are fractured).
