You will use this hands-on activity to help middle school students learn how light refracts.

Engineers are using nanotechnology to create promising new metamaterials that bend and refract light and sound waves in ways not found in nature. There are many potential applications for these materials, one of which is to create "invisibility  fields" for individuals or machinery.

In the media carousel above you will also find:

  • photographs to guide you in accurately setting up the laser refraction challenge
  • the "Build the Future" introductory video to be shown to students at the beginning of your presentation
  • the PowerPoint presentation that highlights the many different types of engineers
To prepare for your classroom visit, about two weeks in advance, review the information in the Engineer Guide and the materials provided for this activity.
