Stoichiometry: Sizing an Airbag Charge
Guided Lesson · ≈ 55 min · Grade 10 · Chemistry · California
What the teacher typed
- What should students learn?
- Use stoichiometry to determine the mass of sodium azide needed to inflate an airbag to a given volume.
- Anything I should know?
- “Airbags — that's the hook, it's why I teach the unit this way. They just did balancing equations so that part's solid, moles are brand new. Units before they touch a calculator.”

Prior instruction respected: it doesn't re-teach what the class already owns, and it enforces the teacher's rule about units.
A real run through the product — the lesson, its materials and its adaptation, exactly as the teacher received them.
Matched from the objective against California’s own standards — the teacher didn’t pick these.
Use mathematical representations to support the claim that atoms, and therefore mass, are conserved during a chemical reaction.
