Reflection Questions

How does Rosemary reinforce the distinction the between the properties of materials and their function? Why is this important?

For students to think like engineers, they must be able to evaluate materials in terms of how well they serve a function. Practice with these terms and the understanding the difference between them will increase understanding of the engineering process.

  • Rosemary explicitly uses the term "property" and distinguishes it from function in her introduction. (1:15)
  • She describes a property as a characteristic, and mentions what a material looks like, what it is made of, and what color it is. (1:20)
  • Rosemary is pushing her students to realize that some functions of a package, such as “to protect,” can easily be accomplished by using either base material, but others, such as “to display” are easier to meet by using one material or the other. (3:41 and 4:42)
