Spread the Word!
Make sure your school and community are aware of where the event is, what time it starts, and what the purpose of the day is! Perhaps your students could make posters and infographics to pop up around the school.
After the Clean Up Event finishes, make sure all waste is disposed of correctly (including sharp items). As an interesting activity (and to promote critical thinking), get your students to assess the rubbish that they found, and brainstorm ways to reduce littering.
Your Clean Up Event could potentially spark a chain reaction of fundraisers, community initiatives and ongoing waste-reduction programs in your school!
