Online Activity: Chemical Kinetics and the “Radium Girls”
Dean Campbell | Mon, 12/20/2021 - 12:17
The classic classroom or lab activity using coin flips to illustrate the first order kinetics of radioactive decay is connected to the tragedy of radiation exposure of workers at facilities using radium-containing luminescent paint. Some of the chemistry related to the contamination of these “radium girls” is explored, with connections being made to the Principles of Green Chemistry and the United Nations Sustainable Development Goals.
ChemBasics Talk: Explore Chemical Reactions with Sarah English
Chemical Reactions is a topic that unites a number of skills from formula writing, balancing equations, predicting products and solubility to name a few. Our presenter, Sarah English, will explore the phenomenon of burning steel wool in a chemical reactions storyline and show how this topic provides a seamless transition into future concepts such as oxidation and reduction chemistry, organic chemistry and stoichiometry. Register for this (FREE) hour long Zoom meeting to be held January 13th, 2022, at 8pm EST.
Gas Laws with Daniel Radoff

Food Dyes as Acid-Base Indicators
Tom Kuntzleman | Sun, 11/28/2021 - 10:51
Natural food dyes are being sold online and in stores that can be used as acid-base indicators. These dyes open up a host of possibilities for at-home and in-class. For example, these food dyes can be used as indicators in the quantitative titration of the Mg(OH)2 in milk of magnesia.
A Polystyrene Model of Polystyrene Tacticity
Dean Campbell | Sun, 11/21/2021 - 10:55
Thin sheets of polystyrene can be patterned with permanent markers to represent repeating units of the polymer and then shrunk down in size using heat. The shrunken models of the repeating units can be connected with a string and then flipped into positions to demonstrate different types of polymer tacticity.
