After a short lesson about batteries, my first grade scientists used a battery to make simple circuits. For one of our circuits, we used a C battery and a section of Christmas lights. I demonstrated how to strip the ends to reveal the wires.
We also used energy sticks to create human circuits. This is such a fun science tool! The entire class held hands to complete the circuit and then we divided into small groups to experiment with them. Click here to learn more about how the energy stick works.
