| Description | Students apply their knowledge of linear regression and design to solve a real-world challenge to create a better packing solution for shipping cell phones. They make composite material packaging containers using cardboard, fabric, plastic, paper and/or rubber bands to create four different-weight prototype versions. They test three of them, using a piece of glass to represent a cell phone—and use that data to predict via linear regression the maximum yet safe height from which the fourth prototype can be dropped. Students apply their knowledge of linear regression and design to solve a real-world challenge to create a better packing solution for shipping cell phones. They use different materials, such as cardboard, fabric, plastic, and rubber bands to create new “composite material” packaging containers. Teams each create four prototypes made of the same materials and constructed in the same way, with the only difference being their weights, so each one is fabricated with a different amount of material. They test the three heavier prototype packages by dropping them from different heights to see how well they protect a piece of glass inside (similar in size to iPhone 6). Then students use linear regression to predict from what height they can drop the fourth/final prototype of known mass without the “phone” breaking. Success is not breaking the glass but not underestimating the height by too much either, which means using math to accurately predict the optimum drop height. |
