[This post is part of our series, Engineering Practices in the Classroom, which explores what engineering practices are, why they matter, and what they look like in real classrooms. Today, we’re focusing on another core engineering practice: exploring the properties and uses of materials to inform design decisions.]
Everything humans have ever made—from the earliest stone tools to running shoes and satellites—depended on choosing the right materials. Engineers spend a lot of time exploring how materials behave so they can match those properties to a specific goal. Bridges must be made of materials that are strong and durable. A raincoat needs something flexible and waterproof.
