The EIE Curriculum

Students experiment with reflecting light using mirrors and learn about light intensity.

Reflection Questions

What do you notice about the way Jessica structures the Light Path activity?

Rather than just reporting on what happens when the light passes through cards A and B, Jessica has students engage more deeply with the content by predicting and discussing results in small groups.

  • Before any testing is done, Jessica has students share their predictions about how the light will travel. (4:50)
  • Instead of having one student report out about the results, Jessica has all groups turn and talk with each other about what they observe. (5:15)
  • Jessica then summarizes the student comments, clarifying important points such as whether the paths are straight or parallel. (5:36)

What challenges do you see students facing in the Angle of Reflection activity?

The activity requires careful setup, precise measuring, and mastery of certain vocabulary.

  • The difficult vocabulary, like "angle of incidence" and "angle of reflection," might be off-putting for some students. (6:51)
  • To get a clear light path, the the setup of the mirror, slotted card, and worksheet has to be exact. We see some groups tinkering to achieve the correct placement. (7:46)
  • Measuring with a protractor might be a skill that requires practice. (8:20)
