Essential question: How can energy models guide better designs?
Five detailed lessons, two safe interactive energy-system labs, Sankey flow model, engineering constraints challenge, educator guide, data cases, games and open-book mastery. Original daily student journals remain below.
A device loses useful energy through multiple pathways.
Build an initial model and explanation for: How can energy models guide better designs?
Record observations, questions, an initial model, and one claim that could be tested. Use these concepts where relevant: energy transfer; thermal loss; efficiency; criterion; constraint.
Study and explain the week's core ideas: energy transfer; thermal loss; efficiency; criterion; constraint
Trusted energy-system case study.
Revise Monday's model. Add two evidence-backed annotations and explain one limitation or uncertainty.
Sankey-style quantitative energy accounting.
Show units, setup, calculation or graph reasoning, then write what the quantitative evidence can and cannot establish about: How can energy models guide better designs?
Energy audit of a simple device/system; no mains-electrical disassembly.
Use the course safety charter. If supervision, facilities, materials, or conditions are not appropriate, use the supplied-data/simulation alternative rather than improvising hazardous procedures.
Record variables or design constraints, procedure/model, observations/data, and one revision you would make after reviewing the evidence.
Answer the essential question: How can energy models guide better designs?
Submit a claim, at least two specific pieces of evidence, reasoning that connects them, one limitation/counterclaim, and a correction note for any essential concept below 80%.
Select one artifact from this week and explain why it is trustworthy evidence of growth.
