I hope to show the periodic table as a fundamental organizing idea relevant not just for chemistry, but all the sciences.  I also hope to stimulate curiosity and instill appreciation of the beauty of science. 

During my research career, I've studied the toxicity of air pollutants and radioactive materials.  I have experience working with hazardous materials. I like to help students understand that materials are often not purely toxic or non-toxic. For example, the element oxygen is absolutely necessary for human life, but breathing high concentrations can damage the lung and other organs.

Although not required, students may find it helpful to have a copy of a periodic table available to refer to during the course. I especially like the tables sold by Theodore Gray. The periodic table display I use is illustrated on my science4man YouTube channel (https://youtu.be/xLR-ZH_8uuM).  I also like the free copy of the periodic table available to download from the Los Alamos National Laboratories website (https://periodic.lanl.gov/index.shtml).
