Grade 8 · Cycle 1 · Week 1 — Thermal Energy & Particle Motion

Learning Goal

Students will develop and use a particle model to predict and describe how thermal energy changes relate to particle motion, temperature, and state in pure substances.

Station Checkpoints

Station 1 — Hook & Phenomenon
Look for: Students connecting the phenomenon to prior knowledge and generating testable questions
Common misconception: Heat and temperature are the same thing — distinguish temperature (average kinetic energy per particle) from heat (total thermal energy transferred)
Station 2 — Investigation / Data Collection
Look for: Accurate data recording and identification of emerging patterns in the evidence
Common misconception: Heavier substances are always hotter — compare equal masses of different materials at the same temperature to show specific heat capacity differences
Station 3 — Sense-Making
Look for: Students revising their model based on evidence collected during investigation
Common misconception: Particles stop moving at 0°C — clarify that particles only stop moving at absolute zero (–273°C); liquid water particles are still in constant motion
