Stoichiometry

Many of us are tasked with planning or teaching chemical quantities and stoichiometry. To support your planning, help you refresh your stoichiometry unit, or provide extra resources to use in your classroom, I have collected some favorite posts on stoichiometry.

I enjoy playing UNO, a popular card game by Mattel, with my family. Students enjoy playing UNO with their friends during lunch or at the end of the day at my school. As a teacher, I have also experienced students having difficulty using dimensional analysis to solve stoichiometry problems. Students have issues with setting up and solving stoichiometry problems.

In 1848 Michael Faraday presented his Christmas Lectures entitled “Chemical History of a Candle” (Hammack and Decoste, 2016).

Stoichiometry often proves to be a challenging topic for high school chemistry students, primarily due to its abstract nature and the reliance on rote memorization for problem-solving techniques rather than a conceptual understanding.

This year, I tried something different with my course progression - instead of doing chemical quantities first and teaching students to convert from grams to mole and then move into stoichiometry, I began with mole to mole stoichiometry and BCA tables.

Every year, my students struggle with the concept of limiting reagents.

"Who Poisoned Veronica Merriweather?" is a fun application of formula stoichiometry for students who are placed in the role of a CSI lab sleuth helping to interpret chemical data to identify a murderer.

If you have seen some of my previous webinars*, you probably have heard me mention that I use interactive notebooks in my chemistry I classes. Today, I’m going to share the first of many units: stoichiometry. Keep an eye out because gas laws and thermochemistry will be coming very soon!
