Sosabowski, Michael Hal; Campbell, David – School Science Review, 2013
This article outlines some engagement or "showmanship" devices that can enhance the impact of live practical demonstrations. The fifteen engagement techniques described herein are used by the author in his spectacular chemistry demonstration shows in theaters, but they can also be useful in the classroom environment. Many of the…

Lehman, Christine; Bensaude-Vincent, Bernadette – Science & Education, 2007
The purpose of the paper is twofold: (1) To contrast the longstanding tradition of private and public courses of chemistry with the public demonstrations of physics. Whether taught in public institutions such as the Jardin du Roi or by apothecaries in their officines chemistry demonstrations were not for the entertainment of their audiences.…

Delaney, Seamus; Redman, Christine – International Association for Development of the Information Society, 2014
This paper describes the utilisation of a technology-facilitated professional learning network (PLN) for pre-service teachers, centred on chemical demonstrations. The network provided direct experiences designed to extend their pedagogical content knowledge on demonstrations in Chemistry teaching. It provided scaffolded opportunities to…

Price, Daniel S.; Brooks, David W. – Chemistry Education Research and Practice, 2012
While lecture demonstrations have been conducted in chemistry classrooms for hundreds of years, little research exists to document the frequency with which such demonstrations are employed or their effect on learners' motivation and performance. A mixed-methods research study was performed, using quantitative and qualitative survey data, along…

Kuntzleman, Thomas Scott; Rohrer, Kristen; Schultz, Emeric – Journal of Chemical Education, 2012
Lightsticks, or glowsticks as they are sometimes called, are perhaps the chemist's quintessential toy. Because they are easy to activate and appealing to observe, experimenting with lightsticks provides a great way to get young people interested in science. Thus, we have used lightsticks to teach chemical concepts in a variety of outreach settings…

Majerich, David M.; Schmuckler, Joseph S. – Journal of College Science Teaching, 2007
A large enrollment, instructor-centered chemistry course taught with science demonstrations was transformed into one that was more student-centered. Course survey and examination results revealed more positive perceptions of the benefits of demonstrations and greater content mastery for students in the modified course than for those in the…

Panzarasa, Guido; Sparnacci, Katia – Journal of Chemical Education, 2013
A revisitation of the classical "mushroom cloud" demonstration is described. Instead of aniline and benzoyl peroxide, the proposed reaction involves household chemicals such as alpha-pinene (turpentine oil) and trichloroisocyanuric acid ("Trichlor") giving an impressive demonstration of oxidation and combustion reactions that…

Xu, Chunxiu; Lin, Wanqi; Cai, Longfei – Journal of Chemical Education, 2016
A demonstration is described of electrophoretic separation of carmine and sunset yellow with a paper-based device. The channel in the paper device was fabricated by hand with a wax pen. Electrophoretic separation of carmine and sunset yellow was achieved within a few minutes by applying potential on the channel using a simple and inexpensive power…

Branan, Daniel; Morgan, Matt – Journal of Chemical Education, 2010
Students everywhere love chemistry demonstrations, especially if they involve explosions. But have you ever wanted to move beyond the "wow" factor and find a way to incorporate active student learning into your demos? What if you could get them to think more deeply about what they're observing, and then find out if they really understand what…
