Major Objectives

  • Distribute reusable bags
  • Educate middle school students about issues surrounding single-use plastic bags


All the science teachers in three middle schools came together to educate students about plastic grocery bags. Teachers worked with the city government to sponsor a project where each student was given a reusable bag. The students decorated their reusable bags with eco-friendly messages and pledged to communicate to five other people the issues surrounding the use of plastic grocery bags. In addition, every science class engaged in a lesson about plastic in the watershed. This project reached over 3,000 students in the city of Pittsburg, California, and many more through the communication pledge.

Notes from the Field

"We're collecting the plastic bags and weaving them into mats for the homeless. We're also designing clothes for our Plastic Runway Fashion Show event."
