Students were also challenged to communicate every step of their engineering process, using CAD models and sketches to explain their designs and detail how their solutions addressed the problem. Presentations included descriptions of the testing process, along with updates and improvements teams made based on their results.
One team's prototype tapped into hens' natural instincts to seek shelter at night. The design used audio alerts to respond when predators were detected, activating a mechanical screen to cover the birds' enclosure and provide an added layer of protection.
Another team developed a system that combined sounds, treats and a timer to deter predators, alert the farmer and encourage the chickens to move into a designated safe space. Once the birds were inside, a protective door would automatically close.
Testing and feedback helped that team take its concept a step further, expanding the product into three different levels to better accommodate the varying needs of potential customers.
Beyond designing a better chicken coop, the project gave students an opportunity to experience the value of the engineering design process firsthand. They learned that successful engineering takes more than a good idea: It requires identifying a problem, developing a thoughtful solution, building and testing a prototype, evaluating results and making improvements along the way.
Just as importantly, presenting their work to an audience challenged students to clearly explain their thinking, defend their decisions and communicate the value of their designs. Through collaboration, hands-on prototyping, problem-solving and iteration, students experienced how engineers turn creative ideas into practical solutions to real-world challenges.
