Week 20 · Term Three · Energy and climate
Work out how much energy solar and wind really make, size batteries for the night, compare the carbon from each source, weigh the options in a decision matrix, and recommend a plan to the town.
Monday turns power and hours into kilowatt-hours. Tuesday sizes batteries with an inequality. Wednesday compares carbon dioxide per kilowatt-hour across coal, gas, solar and wind. Thursday builds a weighted decision matrix. Friday writes a recommendation that is honest about tradeoffs.

Physics · Power, time and energy
Tell power from energy, calculate energy as power × time, and compare total supply with demand.
Make
A energy output card
Vault handoff: The output card is filed. Tomorrow: what about the night?
25 minutes
Algebra · Storing energy for the night
Write and solve an inequality for a real constraint, and round the answer the way the situation requires.
Make
A storage plan
Vault handoff: The storage plan is filed. Tomorrow you count what goes into the air.
25 minutes
Climate · Counting carbon dioxide
Use rates to compare the carbon dioxide from different energy sources, and connect burning fossil fuels to rising global temperatures.
Make
A carbon comparison
Vault handoff: The carbon comparison is filed. Tomorrow the town weighs everything at once.
25 minutes
Engineering · The weighted decision matrix
Evaluate competing solutions with a weighted decision matrix, and show how the weights (the town's values) can change the result.
Make
A decision matrix
Vault handoff: The matrix is filed. Tomorrow you write the recommendation to the town council.
30 minutes
Policy writing · The recommendation
Write a policy recommendation with a clear claim, evidence from data, an honest tradeoff, and the conditions that would change it.
Make
A Energy recommendation
Vault handoff: The recommendation is filed. The energy vault now has a plan the town can check, argue with, and change.
The matrix uses only work entered here. It is a family record of this week’s work, not a grade, an attendance record, or proof of mastery.
