Stoichiometry Will Save Your Life

Curriculum Unit (pdf)


This curriculum unit focuses on using dietary supplements and drugs to discuss the math around stoichiometry. The intent is to make my stoichiometry unit more interesting and relevant to student lives. For calculating basic mole/mass/particle conversions we will look at calcium supplements. Drugs and other dietary supplements will be the focus of empirical and molecular calculations. We will return to calcium carbonate when looking into stoichiometry in an experimental setting. Students will ultimately determine how much calcium ions will be produced from the reaction of various calcium carbonate items (eggshells, Tums, chalk) with hydrochloric acid.
