Trail Trash Timeline: Gone Soon or Here to Stay

A team relay where students lay out common hiking trash along a rope timeline, from what breaks down quickly to what lasts for centuries. It builds respect for nature and group agreement.

How to play

1. Setup: each team has a rope on the ground as a timeline and a cone 15 m away with six cards (tissue, orange peel, gum, cigarette butt, can, and plastic bottle) (2 min).
2. Relay: each runner brings back one card and places it on the line where they think it goes (6 min).
3. Adjust: on each new trip you may move only one card already placed, after a quick team chat (4 min).
4. Reveal the approximate order and compare teams: what surprised you most? (4 min).
5. Zero-waste plan: each team proposes two steps for its next trip and explains them to the class (4 min).

Rules

• Run out on one side of the lane and back on the other.
• Cards are moved only at the line, not while running past.
• Teams talk quietly; no copying other teams.
• We celebrate good reasoning, not just right answers.

Variations

Adaptations

• Limited mobility: be the one who places and adjusts cards on the line while others run.
• Reading difficulties: cards with a big picture plus the word.
• Shy students: be the spokesperson for the plan with a sentence the group prepared.

Learning goals

• Learn how long trash lasts outdoors.
• Reach quick agreements as a team.
• Commit to a leave-no-trace trip.

Equipment for a class of 25

• trash cards: 24
• ropes: 4
• cones: 8

Teacher tip

Breakdown times vary a lot with climate and soil, so focus on the order, not the numbers. Common mistake: thinking organic waste 'doesn't count'; use the orange peel to talk about wildlife and how the place looks.
