(min age: 5th grade) Students will start with $20 horizons dollars. They will be able to go to the horizons carboard shop to buy materials from  cardboard, scissors, duct tape, trash bags, balloons, canoe paddles and more. Then they will be given an object to build out of the materials that must properly perform its given function. Maybe they need to build a boat out of cardboard that will transport one of their classmates across our lake! Or maybe they need to build a nice chair that can hold their chaperone! Whatever the object, students have to plan, budget, build, and test their way to a final product.
