Some time back I introduced my students to play dough circuits. I did this to help them understand circuit basics. I was hoping that some of them would want to challenge themselves in creating art that incorporated circuits. I had a 3rd grade boy that wanted to make his robot light up this week. So, we got to work. This is how we did it.
3V Disc Batteries
#1 Figure out placement for the LED light and battery. Place two lines of copper tape for the negative and positive currents.
#2 Construct a battery holder. My student figured out how to place his copper tape and where the battery should go. I had to help with this part. I cut two pieces of cardboard. One piece fits the battery nice and snug. The other piece will just hold the battery in place.
#3 Next, I had to configure the placement for the battery holder over one of the copper lines. The other copper line will have a hinge that will become a button. I used a small rectangular piece of cardboard to create the button. I added copper tape the back of the hinge. (Remember to not let the copper lines touch each other!)
#4 I added the LED light with some electrical tape. (Remember the longer end is positive!)
Test it before moving on.
I recommend buying the supplies from Amazon. The LED lights are pretty cheap and it made it easy to have everything delivered to me. I keep my LED lights in a jewelry box to keep them organized.
I am wondering what my students are going to come up with next.
