Product Details

An amazing demonstration to teach reflection, waves and frequencies. Reflecting a laser beam off of two spinning mirrors creates an incredible laser light show of beautiful patterns commonly known as Lissajous figures. This demonstration is a real student attention grabber—it is hard to imagine something so beautiful could be created from such a simple demonstration apparatus! Using the unique laser light show board, two versatile Bracken demonstration spinners and a laser will allow you to easily create your own laser images. Complete with detailed Teachers Notes and comprehensive background information.

Concepts: Reflection, Lissajous figures.
Time Required: 15 minutes
Note: Two Bracken demonstration spinners and a laser are required and available separately. A green, high-intensity laser can be used to produce extra clear, crisp laser images.

Performance Expectations

MS-LS2-4: Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations.
MS-ESS3-3: Apply scientific principles to design a method for monitoring and minimizing a human impact on the environment.
HS-ESS3-6: Use a computational representation to illustrate the relationships among Earth systems and how those relationships are being modified due to human activity.
