Before working with the paints, we watched the TED talk from one of the creators of Bare Conductive Paint.
As students explored here were a few of their discoveries.
-The paint takes a while to dry. As the paint dries, the light bulb grows brighter
-Many of the circuits they created didn't work. (Our next step will be looking at the ones that didn't work and try to figure out why)
-The batteries AND the LED's had positive and negative feeds. These had to match up correctly.
-Prepare kids for the time it may take them to figure it out. Support them as they struggle with the ambiguity and the challenge.
-Let kids share out troubleshooting strategies they discover
-Let kids know that it does take a bit for the paint to dry and start conducting.
Here are the specific supplies we used:
3V batteries with PC pins
Bare Conductive Paint pens
5 mm LED's
In the next few weeks, we'll apply what we've learned so far and apply switches, create greeting cards, more develop more sophisticated electric artwork.
