Teacher Monitoring Guide
Grade 8 · Cycle 7 · Week 4 — Synthesis &
Assessment — Extended Applications
Learning Goal
Students will extend their understanding of reaction types and
conservation to evaluate the chemistry of environmental issues (acid rain,
ozone depletion, atmospheric reactions) and design evidence-based
solutions.
Station Checkpoints
Station 1 — Hook & Phenomenon
Look for: Students connecting the phenomenon to prior knowledge and
generating testable questions
Common misconception: Environmental chemistry is different from
classroom chemistry — use the same reaction classification skills to
analyze atmospheric reactions; ozone depletion and acid rain follow
familiar patterns
Station 2 — Investigation / Data Collection
Look for: Accurate data recording and identification of emerging
patterns in the evidence
Common misconception: Environmental problems require only engineering
solutions — balance technological solutions with systemic changes in
chemistry (reformulating fuels, replacing CFCs) as chemistry-driven
solutions
Station 3 — Sense-Making
Look for: Students revising their model based on evidence collected
during investigation
Common misconception: Acid rain only affects areas near emissions
sources — trace atmospheric transport of sulfur dioxide and nitrogen
oxides across regional and international boundaries using data
