In this lesson, students learn how the EV3 Color Sensor works by using Port View.  The ability to  measure brightness (Reflected Light Mode) and distinguish LEGO colors (Color Mode) are explored.

2) Start the video again and pause so you can try the different Color Sensor modes using Port View.

3) Watch the video below for an explanation of how the EV3 Color Sensor detects different colors:

4) Try using different materials so see the brightness (Reflected Light Mode) or which color (Color Mode) the EV3 Color Sensor "sees".

5) Answer these questions:

How does the Color Sensor behave in Reflected Light mode?
How does the Color Sensor behave in Color mode?
