Materials in Today's World

Summary and Final Tasks



In this lesson we discussed the stress–strain behaviors of metals, ceramics, and polymers and the related mechanical properties. Understanding and classifying the properties of materials allow us to design, produce, and utilize materials more efficiently and productively. In some cases, understanding materials allow us to utilize them for new applications. Lesson 4 provides us a language to discuss and compare different materials, while the previous lessons on the classification of materials and atomic structure along with upcoming lessons on the structure of materials will inform us regarding how geometric atomic arrangements and atomic structure can affect materials properties. In the next lesson, we will study how metal atoms arrange to form solids and some of the applications of metals.

Reminder - Complete all of the Lesson 4 tasks!

You have reached the end of Lesson 4! Double-check the to-do list on the Overview page to make sure you have completed all of the activities listed there before you begin Lesson 5.
