Celebrating National Chemistry Week 2015: Chemistry Colors Our World

The October 2015 issue of the Journal of Chemical Education is now available online to subscribers. National Chemistry Week, a community-based annual event uniting ACS local sections, businesses, schools, and individuals in communicating the value of chemistry in our everyday life, is being celebrated October 18–24, 2015 with the theme “Chemistry Colors Our World”. Articles in this issue can help you make the most of this annual celebration.

Blueprint Photography by the Cyanotype Process

In this Activity, students prepare cyanotype paper and use it to "photograph" different items using sunlight. This Activity demonstrates catalysis of chemical reactions by ultraviolet (UV) light using one of the earliest photographic processes, the cyanotype process. It is useful as an introduction to the damaging effects of UV radiation on living organisms and the role of sunscreens.

Hydrogen and chlorine cannon

Hydrogen and chlorine gases can be mixed together without reacting, but when the mixture is struck with bright light, it reacts explosively.
