Stewart Manor School fourth graders in Juliana Yirka’sclass learned about circuits and created their own during a science experiment.
During the science unit, students learned that circuits consist of a power source, switch, wires and lightbulbs. They also learned about series circuits and parallel circuits.
Split into heterogeneous pairs, the students received a baggie with a power source (battery), a switch, wires and three lightbulbs. They were tasked with creating a series circuit using the provided materials in their baggies. Once the series circuits were created, students were asked to remove a lightbulb. Theywere able to see what happens to the other lightbulbs if one was removed.
Following the first activity, students answered the following question with their partner: “Would the electrical energy still be able to flow through the series circuit if a light bulb was removed?” The students were asked to explain their thinking using what they saw from their circuits.
The fourth graders then created a parallel circuit with the same materials. After, they removed a lightbulb from their circuit. Students were able to identify that parallel circuits have multiple pathways for electric energy to travel through because the other lightbulbs were still lit, even though one was removed.
According to Yirka, the lesson was designed to prepare students for fifth grade, as next school year they will complete a science lab called “Light It Up.”
