Brown Bear Bonanza is a collaborative 3d puzzle framework designed for 3rd graders that connects learning with play. We used simple materials, such as cardboard and foam, to inspire younger students to become interested in engineering and design a puzzle that matches their interests. We used a grizzly bear puzzle to demonstrate the collaborative and problem-solving skills required to assemble this, while also tackling the complicated concept of animal endangerment. It's hard for people, especially younger ones, to truly understand the scale of just how many grizzly bears there used to be, compared to how few there are today. The size was chosen to be near life size, but not overly large, and I believe we've struck a nice middle point.
