Learners build

A motorized straw machine that wiggles, walks, and changes direction through balance and vibration.

Learners start by building a lightweight straw frame with a motor and battery, then test how legs, connectors, and balance affect the movement.

From there, they can redesign it as a racer, creature, dancer, maze runner, drawing partner, or wiggling invention with its own behavior.

Build

Learners assemble the core design and see how the parts work together.

Test

They try it, notice what happens, and compare the result with their goal.

Redesign

They make changes, add their own ideas, and improve the build through iteration.

Learners explore

Circuits

Use batteries, wires, and motors to power moving creations.

Mechanical Vibration

Explore how unbalanced parts can shake, wiggle, and create motion.

Iteration

Test, change, and improve a design through multiple tries.

Ready to run with learners

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.
