A no-prep, 5-lesson science unit on KS3 Earth science: the Earth as a source of limited resources and the efficiency of recovering them; human use of resources; the impact of human activity on the environment and ways to reduce it, written for Key Stage 3, Years 7-9 (ages 11-14). Phenomenon-first and three-dimensional: every lesson opens with something to wonder about and builds toward the unit’s big question. Open and teach — full teacher plans, projectable slides, three differentiated pupil worksheets per lesson, a complete printable lab pack, a knowledge organiser, and a baseline + end-of-unit assessment.

Big question: Why are Earth’s resources where they are, and how can we live on Earth without using it up?
