📸 Campus Litter Evidence Walk

In small teams, students complete a fast campus walkthrough with clipboards, a simple photo map, and tally sheets to document where litter appears most often and what kinds of waste they notice. Back in class, teams compare evidence, note at least one possible counterclaim about why litter happens, and draft an initial claim about what the school should do first. Students share with a partner for quick feedback, revise one sentence for clarity, and submit an evidence log entry that will carry into the next phase.
