The Viewed in Another Light Interactive is an adjustable-size file that displays nicely on smart phones, on tablets such as the iPad, on Chromebooks, and on laptops and desktops. The size of the Interactive can be scaled to fit the device that it is displayed on. The compatibility with smart phones, iPads, other tablets, and Chromebooks make it a perfect tool for use in a 1:1 classroom. 

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're going to be honest. We never intended to put this activity in our simulation section. It is (and should be) a student lab activity. But we also never expected COVID19 to shut down schools across the world and leave teachers devoted to hands-on science in quite a pickle as they were restricted to an equipment-less eLearning environment. This Interactive is an attempt to put the hands-on in front of students so they can view real data during the COVID19 pandemic. What we are saying is ... this is really a lab first and a online ineractive second.

The Viewed in Another Light Interactive is one of several Interactives in this section that pertain to the topic of color addition, color subtraction, and color vision. In this Interactive, learners explore how colored lights affect the appearance of five different M&Ms. The learner can view he same five M&Ms under five different lighting environments. We have provided a classroom-ready exercise for use with this Interactive. The exercise is intended to help students process the observations. After making observations, students are asked to analyze their findings and to draw consistent conclusions. 


Related Resources

There are numerous resources at The Physics Classroom website that serve as very complementary supports for the Viewed in Another Light Interactive. These include:
  • 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.

  • Curriculum/Practice: Several Concept Development worksheets at the Curriculum Corner will be very useful in assisting students in cultivating their understanding of color vision, most notably ...

    Reflection, Transmision, and Color
    Color Addition and Subtraction
    Viewed in Another Light
    Pigments and Paints

    Visit the Curriculum Corner.

  • Labwork: 
    Simulations should always support (never supplant) hands-on learning. The Laboratory section of The Physics Classroom website includes several hands-on ideas that complement this Interactive. Four notable lab ideas include ...

    Color Addition Lab
    Taking Away from RGB Lab
    Painting with CMY Lab
    Filtering Away Lab

    Visit The Laboratory.
