Our Changing Planet: Resources and Human Impact Grades 5–8 · partly supports this outcome

Where the copper, cobalt, lithium, oil and sand in a phone come from and why, which energy sources refill and which do not, what real population and energy data say about people and resources, and how real towns cut their waste. Four no-materials lessons built on printed data cards, with a hopeful, evidence-first tone for Earth Day or any time.

• How can a town use less and waste less? 50–60 min

  Teams act as a town council with a waste problem. They rotate around four stations describing what real places did, from Ljubljana's food-waste collection to Kamikatsu's 45 sorting bins, score each against criteria and constraints, and design a plan with a way to measure whether it works.
