This engaging video introduces young learners to the engineering design process through a relatable narrative featuring Jessi and her robot mouse friend, Squeeks. When Squeeks faces the problem of trying to invite too many friends over to play one by one, Jessi guides him—and the viewers—through using engineering principles to find a better solution. They define the problem, identify constraints (like the need for friends to both see and hear the signal), brainstorm ideas, and build a prototype using LEGO bricks and sensors. The video covers key STEM themes including the definition of engineering, the importance of collaboration ('two heads are better than one'), the concept of a prototype as an early model, and the role of sensors in robotics. It also emphasizes the iterative nature of design, showing that the first solution (a small model) often leads to questions about how to scale up or improve the design for the real world. For educators, this video serves as an excellent hook for elementary engineering units. It demystifies the term 'engineer' by framing it simply as problem-solving to make life better.
