Understanding Material Properties

Mr. Andersen discusses the importance of material properties in everyday objects, using examples like scissors and a pepper grinder. He explains how to identify material structures and functions, and how these properties influence design. The video encourages viewers to apply this understanding to their own designs, considering the materials' properties and functions.
