When students were using Snap Circuits last week, one group was creating a design that involved a glass of water. I talked with them about why water was involved in the design. To help show them, I held hands with one student while we each held a piece of the snap circuit wires. Together we completed the circuit when holding hands and broke the circuit when not touching. They couldn't believe how the electricity was actually going through our bodies! More and more wanted to watch, so we decided to make a class chain! Check out our video!
