The students explore how to pack a zero‑waste lunch by sorting packaging, brainstorming ‘swap it’ ideas, and designing a poster of a waste‑free lunchbox.
The intention is to build everyday habits that reduce packaging and food waste, and to empower students to make simple, sustainable choices.
Warm‑up (5′): Show a few Zero-Waste Lunch Box Challenge. Ask: ‘Which makes the most waste? Why?’
Sorting game (10′): In groups, sort items into: Zero-Waste Lunch Box Challenge. Discuss what happens to each pile.
Zero-Waste Lunch Box Challenge (10′): For each single‑use item, propose a reusable or lower‑waste alternative. Write ideas on sticky notes (e.g., juice box → refillable bottle; plastic wrap → small container). Zero-Waste Lunch Box Challenge
Poster making (15′): Design a ‘Zero‑Waste Lunchbox’ poster that shows their chosen swaps, adds 1–2 food waste tips (e.g., pack only what you will eat), and a short slogan. Use Zero-Waste Lunch Box Challenge, Zero-Waste Lunch Box Challengeidea cards.

• Extension: track class waste for a week before/after the challenge.
• Inclusion: allow students to suggest culturally familiar, low‑waste snacks.
