Harbor School Recycling Drive — Pictograph

This pictograph reports recycling bags collected by Harbor School's four houses. The key is intentionally simple: one circle equals one bag. Gold House leads with thirteen bags, followed by Blue House with twelve. Green House and Red House have smaller but still visible totals. Because every circle stands for a single bag, students can verify the numbers by counting and can calculate differences between houses. This makes the chart useful for a school assembly slide or data lesson. It does not indicate the weight or material type of the recycling, so it should not be used to compare environmental impact without additional information.
