We recently started our unit on electricity in 5th grade. To start the unit, we invited GA Power in to do a lesson. If you teach in Georgia and have not utilized this phenomenal FREE resource, you absolutely must!
The presenter did a great job of introducing the idea of an open and closed circuit. The students got to participate in an experiment to test out a human circuit.
When students held hands, we were able to make the magic wand buzz with lights and sound! The circuit did not work if students were covering their hands with sleeves. We brainstormed what might be the cause.
We tested out different materials and sorted them onto the red and green pieces of felt. Red was for insulators and green for conductors.
We continued our unit in science lab the following week. We first built a simple circuit using a batter, a light bulb, and some wires. We tested out different materials to see if the light would shine when the circuit was closed. We found that most materials were either an insulator or conductor. One item - a pencil- could be both.
As we waited for all the groups to finish, we discovered that we could build more complex circuits. We combined two basic circuit kits to create one larger one with two batteries and two lights.
What would happen if we only used one battery? Would all the lights shine?
Thank you to our wonderful parent volunteers that helped support our investigations!
