UNO OUT…..Demystifying Stoichiometry
Nina Hike | Tue, 02/25/2025 - 14:57
This article describes a game aimed at helping students become comfortable using dimensional analysis. Designed to mimic the popular card game UNO, MOLE-O encourages students to think about how to set up a stoichiometry problem utilizing a deck of UNO-like playing cards.
How a Burning Candle Can Teach Stoichiometry
Todd Hollis | Fri, 01/10/2025 - 09:57
Make stoichiometry relatable! In this simple lab, students measure the mass of a burning candle and explore key questions like: 'How much CO₂ does a candle produce?' and 'How can we quantify CO₂ from engines?' Minimal setup, real-world impact, and engaging results!
LEGO Stoichiometry Activity

This quick / low-prep stoichiometry lab helps students visualize why they must convert mass into moles before performing stoichiometry calculations.
Fun with Formula Stoichiometry: “Who poisoned Veronica Merriweather?”
Chris Vyhnal | Fri, 09/16/2022 - 09:47
"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. Topics covered include formula stoichiometry, percentage composition, empirical and molecular formulas and gas chromatography–mass spectrometry.

Does Alka-Seltzer Tell the Truth? A lab activity with a video pre-lab assigment
Josh Kenney | Mon, 11/15/2021 - 08:55
The lab activity shared here is a simple experiment where students use stoichiometric principles to experimentally determine the amount of sodium bicarbonate in an Alka-Seltzer tablet. Novice students tend to find stoichiometric calculations difficult, so practicing the calculations on a pre-lab assignment boosts their confidence and ultimately leads to more successful labs. The Asynchronous Video Pre-Lab Assignment shared here demonstrates the procedure and the calculations required in the experiment.
