Reflection Questions

Where in the video do you see Laura building her students’ vocabulary skills?

Laura takes every opportunity to introduce, reinforce, and reward usage of new vocabulary words.

  • Laura introduces the word “durability” and reinforces the meaning by using hand gestures. (03:29)
  • Laura asks the class for a synonym for the word “multiple.” (7:39)
  • Laura provides positive reinforcement to her students for using new vocabulary to describe the properties of materials. (6:56)

What strategies does Laura use to deepen her students’ understanding of the properties of materials and how certain materials are processed?

Laura brings in visual props and engages students in hands-on exploration of materials.

  • Laura brings in a cotton plant and prompts the class to think about how it went from being a fluffy plant material to the fabric used to make a t-shirt. (0:46-1:12)
  • Before doing any tests, Laura passes out samples of terry and twill to her class and asks small groups to discuss what they observe about the material. (1:58-2:37)
  • After her students have conducted durability tests on the terry and twill, Laura engages the whole class by having each student hold up the sample they think is the most durable. (4:47-5:16)
