Teacher Monitoring Guide
Grade 7 · Cycle 1 · Week 5 — Introduction to Heredity

Learning Goal

Students will use Punnett squares and probability to predict the likelihood of offspring inheriting specific traits, and distinguish between genotype and phenotype.

Station Checkpoints

Station 1 — Hook & Phenomenon
Look for: Students connecting the phenomenon to prior knowledge and generating testable questions
Common misconception: Dominant traits are always more common in a population — use population data to show recessive traits can be more frequent
Station 2 — Investigation / Data Collection
Look for: Accurate data recording and identification of emerging patterns in the evidence
Common misconception: Offspring inherit half their traits from each parent equally for all characteristics — clarify independent assortment for unlinked genes
Station 3 — Sense-Making
Look for: Students revising their model based on evidence collected during investigation
Common misconception: Punnett squares give exact counts, not probabilities — emphasize that ratios are probabilistic predictions, not guaranteed outcomes
