Play games and learn about Great Lakes shipping
|
Have you ever wondered what products are made from the raw materials shipped across the Great Lakes? Or how grain moves from South Dakota to your kitchen? Well wonder no more. The Great Lakes Maritime Research Institute and Michigan Technological University have games to teach you. With Commodities to Products, match finished products like perfume, pet foods and rubber bands to the raw materials they’re made of: iron ore, coal, grain or bentonite clay.
