The class teamed up with Northeast Michigan Great Lakes Stewardship Initiative and Great Lakes Great Responsibility to learn about the impact of litter and microplastics. The class is also working on making a bench out of eco bricks and is just a few bricks away from it being complete. The whole school has been working to take styrofoam and single-use plastic from their lunchroom and putting that in the bricks.
