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!
Manufacture and Use of an Effervescent Antacid
David Cash | Sun, 06/30/2024 - 10:13
A question set about an effervescent antacid formulation unpacks what is occurring both qualitatively and quantitatively. The student will review and apply formulas, balanced equations, percentage elemental compositions, mass-mass calculations, mole-mole calculations, theoretical yield, and limiting reagent.
LEGO Stoichiometry Activity
Josh Kenney | Wed, 05/01/2024 - 10:37
Josh Kenney explains an innovative POGIL-like approach to teaching stoichiometry, integrating LEGO pieces. Addressing student difficulties with stoichiometry's abstract nature, he designed a custom LEGO activity inspired by existing resources, promoting collaboration and enhancing conceptual grasp. This engaging approach primes students for complex stoichiometry challenges.
Quick Lab on Mass vs Moles
Nora Walsh | Tue, 03/05/2024 - 09:08
This quick / low-prep stoichiometry lab helps students visualize why they must convert mass into moles before performing stoichiometry calculations.
Stoichiometry with Beads
Nora Walsh | Tue, 01/24/2023 - 20:04
Teaching and learning the concept of limiting reactants can be challenging. In this activity students manipulate beads to learn about stoichiometry. A virtual drag & drop version is also available.
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.
Spreadsheets, Instant Grading and Feedback during Lab
Chad Husting | Fri, 06/24/2022 - 08:48
Here is a great way to use spreadsheets to both collect student data and provide instant feedback during labs with quantitative data.
Using Interactive Notebooks in Chemistry - Stoichiometry
Nora Walsh | Thu, 04/28/2022 - 09:01
Nora Walsh has been using interactive notebooks for some time. Here she outlines her stoichiometry unit and explains how she uses the interactive notebooks with her students.
