2026–27 INITIATIVE
UN
STOPPABLE
What do we lose when we make everything more efficient?
Students design, build and troubleshoot a Rube Goldberg machine that uses at least three simple machines to do one simple task, and every student writes up how it works through their own subject.

At a Glance
SUBJECTS
ELA, Math, Science, Social Studies
LESSONS
6 per subject: 1 shared launch, 4 subject lessons, 1 shared showcase
TOPICS
Forces, motion and simple machines, linear equations, technical writing, industrialization and automation
FINAL PRODUCT
A chain-reaction machine using at least three simple machines to complete one simple task, plus a written explanation from each student's subject
FACILITATION GUIDE
Lesson plans for all four subjects, slide decks, student handouts, scoring rubric, standards documentation, contest details
WHAT YOU SUPPLY
Cardboard, tape, glue, string, rulers, marbles or blocks, paper, pencils, printed handouts
Teach all four subjects, or just yours — each subject's lessons stand on their own.
THE ARCS
Four subjects, four arcs
Lessons 1 and 6 are shared across all four subjects. In between, each subject's four lessons build on each other, toward what that subject contributes to the final product.

Building, testing and presenting the machine
CONTRIBUTION TO THE PRODUCT
The machine's message: tribute or satire, and why.
THE PRODUCT
One machine, four ways to explain it
Students design a chain-reaction machine that does one simple job in the most overcomplicated way they can manage: ring a bell, raise a flag, drop a ball in a cup. It has to use at least three simple machines. They plan it across the unit, then build, run and troubleshoot it on the build days.
Students who take more than one subject build one machine, not four. Each subject adds a write-up to the same machine.

BEFORE YOU TEACH IT
Watch the walkthrough
A run-through of the six lessons, the instructional design, and the build days, so you know what you're walking into before day one.
What it covers
​
How the facilitation guide delivers your materials, and how to navigate it
How the shared launch works across all four subjects
What a typical lesson looks like start to finish
Running the model build days and the showcase
PACING
When to run it
Unstoppable is flexible. You can run it any time of year and shape the pacing to fit your school schedule: start earlier in the year, stretch the days out, or run it whenever it makes the most sense for your students.
If you're entering the national contest, the only date to plan around is February 26, when student work is due. If you're not entering, Unstoppable stands completely on its own.

CONTEST & SHOWCASE
Enter the contest
Every student who finishes gets a certificate. Facilities may submit their student work to the national contest.
