2015 Chemistry Show
Saturday, October 3, 2015
Purdue University's Department of Chemistry will return to the classics to demonstrate basic principles of chemistry in its annual one-hour show Saturday, Oct. 3, on the Purdue campus.
"Classical demonstrations of chemical phenomena" will be held 10:30 a.m. in Room 200 of Wetherill Laboratory of Chemistry. The demonstrations are geared for children and adults of all ages and the show is open to the public free of charge.
During the show, Paul Smith, lecture demonstration director for Purdue's Department of Chemistry, will draw upon audience participants and a variety of techniques to illustrate chemical principles. Demonstrations will include:
- A "race" designed to illustrate lessons in chemical concentration, measurement and rate of change. Audience participants will compete to produce reactions that cause chemicals to progressively change in color.
- A bubbly brew created to show how the surface tension and composition of solutions work together in producing mixtures.
- A candlelight lesson designed to present information on simple combustion reactions.
- Dividing water and show a modern day use of these products in a fuel cell.
- Burning paper with super-heated water.
