Don't shine like a diamond, refract light like a diamond. Young scientists use an acrylic block and a laser light to observe refraction. Advanced scholars figure the sine of the angles of reflection and incidence as well as mastering Snell's Law. A reading passage and homework questions round out the lesson.

Instructional Ideas
- After the lesson, circle back to give learners the answer to the introductory question
- Moissanite, a synthetic diamond, passes all but one test to differentiate it from natural diamonds; ask pupils to identify that test and figure out if the property is important
Classroom Considerations
- Review laser safety before the activity
- Though the resource includes lessons six and seven, this review is only for Refraction of Light; pupils review lesson seven separately
- Lesson six in a series of eight
- This resource is only available on an unencrypted HTTP website.It should be fine for general use, but don’t use it to share any personally identifiable information
Pros
- Includes vocabulary throughout the lesson
