Designed for Learning

• Minimal prep, maximum impact: Everything you need is in the box, from batteries to brainstorming paper. Just open and go.
• Screen-free and NGSS-aligned: Students practice engineering design and physical science standards without devices or logins.
• Goal-directed but unscripted: With 10 challenge cards, students get direction without step-by-step instructions, encouraging them to problem-solve and think creatively.

Why Teachers Love It 

1. Quick builds, lasting engagement: Challenges can be started and completed within a class period, but students are motivated to keep tinkering. 
2. Authentic engineering: Using the same kinds of materials found in real machines, students experience what it’s like to be inventors, not just builders. 
3. Reusable and open-ended: The kit is designed to be made, unmade, and remade—again and again.
