Two bottles and a bag

Engineers solve problems by following steps: ask what the problem is, imagine ideas, plan the best one, build a prototype, test it and improve it. Here the problem is waste: how can an old bag or bottle become something useful? A bottle can become a pencil pot or a bird feeder with seeds only for wild birds. A bag can become a pouch. A grown-up does all the cutting, so children draw, plan, decorate and test. A team works best when each person has a role, such as the planner, the builder, the tester and the speaker. At the end the team can invent a slogan to remind others to reduce plastic.
