Syllabus mapping — People, Patterns and Processes (2022)

Content: Overview of the diversity and extent of human activity on Earth's surface on a global scale. This chapter is the topic's conceptual opener — it sets up the ecological footprint, sustainability and spatial-pattern ideas that 7.2–7.7 develop.

Activities & model answers

Activity 1 — Define the ecological footprint

A strong answer
The biologically productive land and water needed to supply what a population consumes and to absorb its waste (especially CO₂), measured in global hectares. It is compared against biocapacity (productive area available); when the footprint exceeds biocapacity the population is in overshoot — using nature faster than it regenerates.

Activity 2 — Diversity brainstorm

Look for
A real spread from low-intensity (subsistence farming, small towns, protected areas) to high-intensity (megacities, heavy industry, container ports) and primary industry (broadacre farming, open-cut mining). Reward students who link each to a specific environmental demand (land, water, energy, emissions, waste) rather than just naming activities.

Activity 3 — Read the figure

Key
(1) High-income group has the largest per-capita footprint. (2) Pattern: per-capita footprint rises with income — high > middle > low; the gap is large. (3) Because Figure 7.1.1 is schematic/illustrative (not real data) — quote the pattern, not the numbers; cite the Global Footprint Network for actual figures.

Activity 4 — Key concepts

Indicative
Environment = human activity draws on and degrades natural systems; Scale = individual/local consumption aggregates into a global footprint; Interconnection = one overshoot drives biodiversity loss, climate change and scarcity together; Sustainability = keeping demand within Earth's biocapacity so future activity is possible.

Activity 5 — Short evaluate

Model
Balanced: the diversity and reach of human activity reflect genuine achievements (food security, health, connection), but the scale of demand has pushed the global footprint beyond biocapacity into overshoot, with uneven consequences. A strong answer concludes that sustainability is about changing how activity is conducted (efficiency, renewables, equity), not ending it — i.e. both achievement and problem.

Key questioning (with answers)

Differentiation

  • Support: a pre-filled example row for the Activity 2 table; sentence starters for the Activity 1 definition ("The ecological footprint is the… needed to… and to…").
  • Extension: use the Global Footprint Network / Our World in Data to find a real per-capita footprint for two contrasting countries and explain the gap; research Earth Overshoot Day's trend.
  • EAL/D: visual glossary (human activity, ecological footprint, biocapacity, overshoot, sustainability, Anthropocene).

Assessment & homework

  • Exit ticket: define the ecological footprint in one sentence + name one consequence of overshoot.
  • Homework: the Activity 5 evaluation, written up; read ahead to 7.2 (settlement & economic activity patterns).

Useful resources

Teaching note — numbers & scope. This chapter is deliberately light on hard statistics; the source lesson was thin on verified data. Keep framing qualitative and attributable — the ecological footprint, biocapacity and overshoot are robust concepts; any single figure (e.g. "1.7 Earths", Earth Overshoot Day's date) should be introduced as a Global Footprint Network estimate, not a fixed fact, and looked up live. As the topic's opener, keep it a clear overview — resist teaching the detail of settlement, economic activity or culture here (that's 7.2–7.7).
Provenance: converted from Bill's earlier lesson; facts re-verified and the source's ACARA codes (ACHGK070/ACHGS063) corrected to NSW Geography 11 outcomes (GE-11-01/02/03/09). Figures redrawn as original inline SVG — no textbook images reproduced. Figures 7.1.1 (footprint bars) and 7.1.2 (activity-intensity map) are labelled illustrative/schematic.

🎦 Teaching-presentation — answer & discussion guide

Model points for the reflection, research & essay tasks in 7.1 Diversity & Extent's teaching deck (_teaching.html). Not exhaustive — students should reason & use evidence.

Reflect — “…diverse & extensive — and that is exactly the problem.” Agree?
Research — your own footprint

Look for: a sensible “how many Earths” figure; identifying transport/diet/energy as biggest; two realistic changes with a rough effect.

Essay — diversity/extent + consequences

Reward: a clear definition + Anthropocene framing; the footprint used as evidence; consequences linked & shown as uneven; a sustainability conclusion.
