Flashlight Activity – STEM in the Preschool Classroom

Preschoolers will delight in exploring electronics with this flashlight activity inspired by our friend Karen from PreKinders. Safe and easy, this activity brightens up any classroom and the faces of the little scientists too!

Exploration in the Science Classroom

Often, preschool science lessons seem to require a lot of planning and preparation by the teacher. However, students learn more by DOING. It is a common pitfall to overexplain and have a science activity go exactly as prescribed, instead of allowing for exploration. Instead, provide the materials and ask the students, “Can you fix the flashlight?”

This flashlight activity only requires two items: flashlights and batteries that fit in the flashlights! The flashlights with single batteries are fine, but two batteries require a little more thought and exploration.

Good scientists make predictions, explore, re-evaluate, and learn from their failures. Remind students that failing or not figuring out how the flashlights work at the start is okay. Open investigations, such as this flashlight activity, provide students with the opportunity to make meaningful and memorable connections. Let students take the lead on their learning and watch their enthusiasm grow!

A Note About Batteries

Whenever children are experimenting with batteries, close supervision is required. While this activity is safe overall, batteries can become fatal if ingested. Use caution and supervise children participating in this and other activities involving batteries. For younger students, prevent swallowing with large flashlights with “C” or “D” type batteries.
