Thermal Energy Mastery Review
A comprehensive two-day review sequence covering thermal energy, heat transfer, temperature vs. thermal energy, and particle motion, culminating in a CER practice and exit ticket.
"What happens to the motion and spacing of molecules when ice melts?"
Think: Does ice gain or lose energy as it melts in a warm drink?
C
CLAIM
The direct answer.
E
EVIDENCE
The facts/diagrams.
R
REASONING
The "Because..." (Science logic).
Writing a Great Claim
Good Claim:
"When ice melts, its molecules move FASTER and become FURTHER APART because they are gaining thermal energy."
Pro-Tip: A claim should NEVER start with "I think" or "My answer is". Just state it as fact!
The Reasoning "Glue"
Linking it Together
"Since the drink is warmer than the ice, thermal energy transfers into the ice. This increases the kinetic energy of the particles, causing them to break free from their solid structure and move more freely."
Key Term 1
Heat Transfer
Key Term 2
Kinetic Energy
Final Boss: The Exit Ticket
Mission Checklist
Identify the direction of energy flow (always Hot to Cold).
Explain why objects with more MASS have more Thermal Energy.
Describe particle motion changes during heating and cooling.
Mission Accomplished

2. Least Energy to Heat:
Correct Answer: A (25 mL). Smaller mass requires less energy to reach a target temperature because there are fewer molecules to speed up.
3. More Ice:
Correct Answer: More ice means there is more mass that must undergo a phase change. This requires more total thermal energy to be transferred from the environment before the temperature of the drink can significantly rise.
