Light Through Windows

Have you ever noticed how light in a room changes throughout the day?


Instructions

  1. Press the play button and closely watch what happens to the light coming through the classroom window over the course of a school day.

  2. You can move the time slider (or even the sun), to slow down the animation and take a closer look.

  3. Using the window orientation drop down, change the direction the window faces. What happens to natural light in the classroom now?
