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. 

Aluminum & Air Battery

In this Activity, students construct a simple battery from aluminum foil, saltwater, and activated charcoal. The battery can power a small motor or light. This Activity demonstrates oxidation and reduction reactions, which are integral parts of battery chemistry.
