Use batteries, wires, and motors to power moving creations.
Learners build
A battery-powered car with a real circuit, gears, and wheels that learners redesign themselves.
Learners start by snapping the motor onto a cardboard base, adding an axle with a gear that meshes with the motor gear, and connecting the battery. Swapping the two wires reverses the polarity and sends the car backward.
From there, they take the car apart and redesign it with paper tubes, straws, and scissors to make it smaller, faster, three-wheeled, or able to drive in circles. It connects English language arts with science and engineering.
Educator Resources
Student-facing slides introduce the concepts, guide the activity, and help learners reflect on what changed. Educator materials support setup, pacing, discussion, and extensions so this can work in classrooms, libraries, homeschool groups, clubs, or makerspaces.
