Oftentimes engineers have to pick the right materials for their designs. Certain materials give desirable properties that can make a design more effective. For instance, polymer based designs are often light, strong, and flexible. Thus, parachutes are commonly made from polymer-based materials to utilize these properties. Why do you think aluminum foil would be a bad material to make parachutes?
Another important property of parachutes is aerodynamics. Certain shapes will catch the wind better than others. What kind of shapes do you think are great for parachutes?
From a variety of materials, students will make an effective design that is strong, light, and aerodynamic, so that Mr. Lego Man will land to safety.
This Guide provides the instructor information on how to run the design challenge with alternatives for materials and test setups as well as information to help make the design challenge a good educational experience.
The video conveys the societal impact of the student’s research that is the basis for the design challenge and will set the problem-solving context for students. The video also leads students through the design process. It indicates materials available, states what the criteria are for success and any constraints.
