In this lesson, 1st-grade students explored the basics of circuits by building snap circuits that produce light and sound. The lesson began with a discussion about how electricity flows through circuits to power devices, introducing key components like power sources, switches, and outputs (lights and sound). Students worked in small groups to assemble snap circuits following simple diagrams, experimenting with different configurations to create glowing lights and buzzing sounds. They observed how completing a circuit allowed energy to flow and how breaking it stopped the flow. After building their circuits, students reflected on their experiences, sharing what they learned about circuits and how light and sound are used in everyday life. This activity aligned with science standards (S1P1) by exploring energy and material interactions, fostering collaboration, problem-solving, and hands-on learning.
