Jessi and Squeaks Build a Better Back-Scratcher!

The video tutorial guides viewers through the engineering design process to solve a problem. The host and Squeaks work on creating a back scratcher to address an itchy back. They follow the steps of asking questions, imagining solutions, creating prototypes, testing them, and improving the designs. The process emphasizes the importance of iteration and creativity in engineering problem-solving.

How did Squeaks' design differ from the initial back scratcher?
