Element of the Month - Oxygen

In honor of the International Year of the Periodic Table: A familiarity with the chemistry of some of the elements more commonly encountered in everyday life is a valuable learning experience for all students. Oxygen is the second in this series of elements to be discussed as part of the Element of the Month program. #IYPT

Drawing Particulate Models

Embracing the idea that students already create an image, create an idea, of what is happening when they observe a demonstration, lab or activity. The goal is to have the students make that model more concrete through drawing it.

Hoffman Apparatus on the Go....

There are many places online to build a DIY Hoffman apparatus. The ACS offers an electrolysis of water lesson that includes a hand made Hoffman apparatus(link is external) as part of a unit on energy that I used as a resource. 

Electrolytic Dissolution of Copper Metal

Looking for an easy, hands-on experiment to use in your classroom at the beginning of the school year? In the June, 2013 issue of the Journal of Chemical Education, Isao Ikemoto and Kouichi Saitou describe a simple experiment to demonstrate the electrolytic dissolution of copper ions from a copper electrode. This experiment can be conducted using only items that are easily obtained around the home or in grocery stores.
