THE CHALLENGE: Green Design

Content: Materials, Improve a design, Create a prototype
Theme: Green

Engineers find ways to improve existing products. One way to make an item better is to use fewer raw materials to make it.

In this hands-on challenge, students consider ways to repurpose materials and invent an environmentally friendly beverage can holder. In the process, they consider what it means to be "green," identify low-impact alternatives for common items, and use the design process to devise a "green" packaging system for beverage cans.

IN CLASS

Spark students' thinking about what it means to be "green" by giving them a problem to solve and asking them to build a prototype.

AT HOME

During this "At Home" challenge, students will search their homes for products that have environmentally un-friendly packaging and then will create a sketch or prototype that improves upon the original design.

CLASSROOM WRAP-UP

Explore the examples gathered in the "At Home" challenge, and then discuss students' prototype designs. Follow this up by watching what a professional engineer is doing in this field, and what three students created as a part of the "Trash to Treasure" challenge.
