Chapter 3 · Energy, Heat & Thermal Design
Assigned readings
This is the parent timetable. Learners follow chapter and unit names. Each chapter uses four consecutive weeks; dedicated consolidation, project, sample, and exam weeks make the complete 36-week plan.
This week’s goals
- Complete the named teaching, practice, investigation, or assessment tasks.
- Preserve quantities, mechanisms, and a meaningful evidence limit.
- Save a revised explanation and identify any concept needing reteaching.
Read the linked chapter opening and the background/short teaching parts named in each session. All required case information and investigation records are supplied on the site; external references are optional extensions. On assessment days, use the paper’s provided scenarios and relationships.
Five suggested 35–45-minute sessions. Midterm response blocks total 90 minutes; final response blocks total 135. The sample uses 45 minutes. Actual optional drying/observation can span longer intervals; use the supplied records when necessary and extend teaching for comprehension.
Session 1 · Conduction, Convection & Radiation · Model and explain
Light and infrared radiation can transfer energy across space. An object can emit and absorb radiation; the net exchange depends on temperatures and other properties. Visible brightness alone does not give the full energy account. Identify several relevant pathways instead of forcing a whole situation into one label. A cup can exchange energy through its wall, moving surrounding air, radiation, and evaporation. Insulation changes some rates without making every pathway zero.
Your task
For Conduction, Convection & Radiation, study Parts 3–4 and attempt the worked case: Explain all three pathways and what a fitted sleeve might change. Explain the steps before opening the model.
- Prepare (5 minutes): retrieve the relevant idea and state today’s question.
- Read/examine (10 minutes): use the linked unit, diagram, or supplied record; note units and conditions.
- Apply (15–25 minutes): complete the task, showing evidence and reasoning before opening guidance.
- Reflect (5 minutes): revise one choice, explain the correction, and save the work.
Hint and response guidance
Begin with the actual observation, quantity, or diagram relationship. Explain how it bears on the question before making a broad claim.
Conduction transfers energy through the wall; moving air can carry energy by convection; infrared radiation exchanges energy with surroundings. A sleeve can reduce some transfer through the wall and alter airflow, depending on its design. It does not guarantee zero cooling or prevent radiation by definition.
- An accurate scientific claim answering the actual question.
- Relevant evidence or a labeled model with quantities and units when applicable.
- Reasoning that connects evidence with the mechanism rather than only repeats it.
- A specific method, boundary, scale, or alternative-explanation limit.
Session 2 · Conduction, Convection & Radiation · Practice, revise and exit
Use practice as evidence of understanding. A selected definition can be checked automatically, while a written explanation needs human comparison with its mechanism and limits.
Your task
For Conduction, Convection & Radiation, complete practice questions 1–6 and both choice checks, then answer independently: An object is warmed from the side by radiation. Must the energy move upward? Save a correction explaining one changed claim or method.
- Prepare (5 minutes): retrieve the relevant idea and state today’s question.
- Read/examine (10 minutes): use the linked unit, diagram, or supplied record; note units and conditions.
- Apply (15–25 minutes): complete the task, showing evidence and reasoning before opening guidance.
- Reflect (5 minutes): revise one choice, explain the correction, and save the work.

No. Radiation can travel in many directions. Rising warm fluid is a separate situation involving convection and buoyancy.
- An accurate scientific claim answering the actual question.

- Reasoning that connects evidence with the mechanism rather than only repeats it.
- A specific method, boundary, scale, or alternative-explanation limit.
Session 3 · Thermal Design: Compare, Improve & Retest · Read and distinguish
Define success before seeing the results. A measurable criterion might be a temperature drop of no more than 6 °C over ten minutes; a constraint might prohibit electricity and limit materials. Different criteria can favor different designs. Use equal liquid amounts, matched starting temperatures, lids, surroundings, and timing. Repeat fresh trials and record all of them. A lower final temperature might reflect a cooler start instead of worse insulation.
Your task
For Thermal Design: Compare, Improve & Retest, read the background and chapter opening, study Parts 1–2, and write two observation/idea notes with the checkpoint responses. Keep calculations and units when applicable.
- Prepare (5 minutes): retrieve the relevant idea and state today’s question.
- Read/examine (10 minutes): use the linked unit, diagram, or supplied record; note units and conditions.
- Apply (15–25 minutes): complete the task, showing evidence and reasoning before opening guidance.
- Reflect (5 minutes): revise one choice, explain the correction, and save the work.
Hint and response guidance
Begin with the actual observation, quantity, or diagram relationship. Explain how it bears on the question before making a broad claim.
It defines which designs are feasible. Choosing a performance winner first and ignoring its cost changes the original problem. No. Use matched starts and compare drops over the same interval before attributing the difference to the sleeves.
- An accurate scientific claim answering the actual question.
- Relevant evidence or a labeled model with quantities and units when applicable.
- Reasoning that connects evidence with the mechanism rather than only repeats it.
- A specific method, boundary, scale, or alternative-explanation limit.
Session 4 · Thermal Design: Compare, Improve & Retest · Model and explain
Compare performance with every relevant criterion, not just one attractive value. Explain what the evidence establishes and whether variation could affect the decision. A slightly better average may not justify a much higher cost or waste. Change a specified feature connected with a transfer mechanism, then repeat the fair comparison. Keep earlier results to show why the change was chosen. Improvement under one setup does not establish performance in every environment.
Your task
For Thermal Design: Compare, Improve & Retest, study Parts 3–4 and attempt the worked case: Calculate the means, recommend a feasible design, and propose a next test. Explain the steps before opening the model.
- Prepare (5 minutes): retrieve the relevant idea and state today’s question.
- Read/examine (10 minutes): use the linked unit, diagram, or supplied record; note units and conditions.
- Apply (15–25 minutes): complete the task, showing evidence and reasoning before opening guidance.
- Reflect (5 minutes): revise one choice, explain the correction, and save the work.
Hint and response guidance
Begin with the actual observation, quantity, or diagram relationship. Explain how it bears on the question before making a broad claim.
C has mean drop 6 °C and costs 3 tokens, meeting both stated conditions. D has mean 4 °C but exceeds the budget. Recommend C for this modeled problem, while noting its 5–7 °C spread and repeating to check consistency. A cheaper D variant would need its own fair test.

Session 5 · Thermal Design: Compare, Improve & Retest · Practice, revise and exit
Use practice as evidence of understanding. A selected definition can be checked automatically, while a written explanation needs human comparison with its mechanism and limits.
Your task
For Thermal Design: Compare, Improve & Retest, complete practice questions 1–6 and both choice checks, then answer independently: A design reaches the best temperature in one trial but cannot fit the cup. Is it necessarily the best solution? Save a correction explaining one changed claim or method.

Parent / teacher weekly conference
Read aloud in short sections if needed and ask the learner to explain an observation before its cause. Compare written reasoning with the criteria and actual records, accepting supported alternatives. Keep learner answers and marks separately backed up. No personal disclosure, public posting, or product purchase is required.
- Can the learner state what was observed and what is inferred?
- Are units, time, scale, and boundary appropriate?
- Does the mechanism explain the evidence rather than merely label it?
- What specific distinction needs another example before proceeding?
