By the end of the lesson, students will be able to:

1.   Describe the environmental impacts of the smartphone life cycle. Students examine how a full life‑cycle assessment covers raw material extraction, production, distribution, use and end‑of‑life treatment and understand that manufacturing generates about 50 kg of CO₂‑equivalent per device.
2. Interpret global e‑waste statistics and explain the need for circular economy models. Using recent UN data (62 million tonnes of e‑waste produced in 2022 with less than 22 % properly recycled and only 5 million tonnes from small IT and telecom equipment), students contrast the linear take‑make‑waste model with circular approaches.
3. Evaluate personal smartphone use and propose actions to reduce environmental impact. Students recognise that production processes account for over 80 % of the global warming potential of a phone and that extending device lifetimes and ensuring proper recycling are among the best ways to lower impact.
4. Develop digital and collaborative skills. Students navigate an interactive global e‑waste map to compare per‑capita e‑waste generation and formal collection and collaborate on designing a school‑based circular‑economy initiative.
