Overview

Chemical Reactions & Stoichiometry is a Grade 11 Science lesson bundle for Alberta that focuses on chemical stoichiometry, reaction calculations, and evidence-based reasoning, with 15 targeted worksheets.

The included practice moves from core reaction quantities (moles, molarity, gas volumes) to limiting reagents, percent yield, net ionic equations, and balancing chemical equations, so students can connect quantitative work to chemical change.

Use the set to support consistent strategies across multi-step problems, from titration-style thinking to combustion and industrial efficiency contexts.

Skills & Standards

Aligned to Alberta’s science focus on developing scientific thinking, this unit emphasizes disciplinary core ideas in chemistry: matter conservation, conservation of mass, reaction models, and the relationship between particle-level processes and measurable quantities. Students repeatedly apply modeling and analytical reasoning by translating balanced equations into mole-based calculations and then interpreting results.

Across the set, learners strengthen evidence-based explanations by connecting calculation outcomes (theoretical yield, percent yield, limiting reagents, oxygen demand) to what would plausibly happen during real reactions. They also practice crosscutting concepts such as systems and models (using balanced equations as models of chemical change), and energy and matter conservation (including enthalpy-related reasoning and conservation of mass checks).

Key skills developed include computing molarity and solution quantities, determining oxidation states, generating net ionic equations, using gas laws within stoichiometry workflows, and justifying final answers through appropriate unit conversions and consistency checks grounded in chemical stoichiometry.

How to Use

Plan this single Grade 11 unit for a typical 1–3 week pacing, selecting worksheets to match your class sequence (for example, start with balancing and mole foundations, then move into titration/solution stoichiometry and limiting reagents, and finish with redox, gas/combustion, and evidence-based applications).

Try a short warm-up each day (e.g., one balancing task or one mole-conversion question), followed by guided practice on the day’s core calculation type (limiting reagents, percent yield, or gas stoichiometry). Use exit tickets that require a full chain of reasoning and interpretation (not only an answer), such as identifying the limiting reactant, explaining percent yield meaning, or determining oxygen demand from a combustion equation.
