Quick Lab on Mass vs Moles

This quick / low-prep stoichiometry lab helps students visualize why they must convert mass into moles before performing stoichiometry calculations.
BCA Tables
Balancing Equations, Candy and an Evolving Activity

I feel like every year I face the same old dilemma. It starts with an idea in mind of what and how something should be taught. This idea is fine until it is discovered that students this year are different than students last year. The idea is changed or “tweaked”. The process is feels similar to having to “reinvent” the wheel each year. This gets exhausting.
Increasing Access to Stoichiometry Through Differentiated In-Class Practice

In a recent post, I shared sample quiz questions as to how I have differentiated assessment within the mole unit. Here, I share a specific multi-day sequence within the stoichiometry unit. I have written extensively about the project that drives this unit (within the following blog posts: Why consider trying project based learning?, Backwards planning your PBL unit - An Overview of an Entire Unit and What ARE my students actually learning during this long term project (PBL)?), but very little about specific learning tasks. Below is a two day sequence of stoichiometry practice that I set up in my classroom. Stations are set up around the room and students rotate as necessary.
One teacher's attempt to use BCA Tables for Stoichiometry

In this blog post I'll describe a recent attempt at using BCA Tables for teaching stoichiometry. I discuss the method I used with one introductory chemistry class to teach both the algorithm method and BCA tables to learn more about a technique I've been curious about for a while.
