First Grade Communicates With Light

In their final session in the Lab for this school year, our first graders had a chance to use the breadboard circuit they made last class to communicate to their partner. 

First the students had to come up with a list of words that they were going to use in their communication. Next they discussed and created the "code" for each word, based on the 7 possible colors created by the RGL LED.

Next, sitting back to back, the students created a sentence that they wanted to "say" to their partner, just using the lighting combination of their breadboard circuit.

Last, using their code, they sent their light signal to their partner. The partner had to record the code and then translate it when they were done.
