Stage Lighting Notes
Notes:
This Interactive does use a newer technology known as WebGL. WebGL is a JavaScript-based technology that is built into most modern browsers on mobile devices as well as desktop/laptop browsers. Older browsers may not be WebGL compliant or may not offer it as a standard feature but allow it to be enabled by the user of the device. For instance, the Safari browser has an Enable WebGL option in its Develop menu. Without enabling WebGL, the use of WebGL JavaScript code is not functional and would not work in such browsers. We expect that future browsers will all be WebGL-compliant and we have thus used this technology for the creation of this Interactive. Additional information about WebGL can be found on Wikipedia.
Teaching Ideas and Suggestions:
We have provided a classroom-ready exercise for use with this Interactive. The exercise is intended to help students process the observations from interacting with the Stage Lighting simulation. After making observations, students are asked to analyze their findings and to draw consistent conclusions. We would like to thank Physics Teacher Judy Kolb Rieke of Ursuline Academy in St. Louis, Missouri who reached out on Facebook to share with us her idea of how she uses our Interactive. We adapted the exercise from what she sent us and the rest is history.
If you're a teacher and you have an idea for an exercise to go with one of our Interactives, then why not do what Judy did. Please share your idea with us on social media.

- Reading:
Lesson 2 of the Light and Color Chapter of the Tutorial are perfect accompaniments to this Interactive. The following pages will be particularly useful in the early stages of the learning cycle on light and color:
The Electromnagnetic and Visible Spectrum
Visible Light and the Eye's Response
Light Absorbtion, Reflection, and Transmission
Color Addition
Color Subtraction
- Minds On Physics Internet Modules:
The Minds On Physics Internet Modules include a collection of interactive questioning modules that help learners assess their understanding of physics concepts and solidify those understandings by answering questions that require higher-order thinking. Assignment LC5 of the Light and Color module provides a great complement to this Interactive. It is best used in the middle to later stages of the learning cycle. It would be a great follow-up to the use of this Interactive. Visit the Minds On Physics Internet Modules.
