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.
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.
This quick / low-prep stoichiometry lab helps students visualize why they must convert mass into moles before performing stoichiometry calculations.
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.
"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.
Here is a great way to use spreadsheets to both collect student data and provide instant feedback during labs with quantitative data.
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.
Engage your students with this stoichiometry scavenger hunt!
The unspoken word of chemistry: Non-stoichiometric. Stoichiometry and non-stoichiometry are concepts that combine to make a solution that does not have to be difficult to understand.
Natural food dyes are being sold online and in stores that can be used as acid-base indicators. These dyes open up a host of possibilities for at-home and in-class. For example, these food dyes can be used as indicators in the quantitative titration of the Mg(OH)2 in milk of magnesia.
