A 7th grade science class is designing a year-long ecology project on recycling. Students will calculate waste by weighing trash, counting discarded recyclable bottles, and estimating the amount of paper placed into wastebaskets in school classrooms. Students will then create posters and an information booth to be set up in the school cafeteria, where materials and background information on recycling will be distributed to students. At the end of the year, students will redo all calculations to determine if the amount of trash has decreased and recycling has increased.
