The Wow We Grain Crusher kit (SP_17) is a practical Technology / PAT mechanisms project — learners build a wooden crusher model and explore how gears, levers, and crushing force work together.
This guide covers the classroom idea, how to plan the build, and where to buy the kit in South Africa.
### What this project teaches
• Mechanisms: gears, levers, and mechanical advantage
• Force and motion in a simple processing machine
• Design–make–evaluate skills for PAT write-ups
• Optional context: food processing / agricultural engineering
Real grain crushers are industrial machines. This school kit is a safe wooden classroom model of that idea.

### What you may need besides the kit
• Wood glue (and drying time)
• Optional paint or markers for labelling parts
• Soft test material if instructions allow (never force hard objects)
• Ruler for checking alignment
### Suggested classroom plan
1. Intro: what a crusher does; where force comes from in the mechanism
2. Identify input (handle/crank) vs output (crushing action)
3. Dry-fit gears and frame; check mesh before gluing
4. Assemble frame first, then mechanism; let glue dry
5. Test gently; note where friction or binding happens
6. PAT write-up: labelled diagram, method, results, improvements
### Common mistakes
• Gluing gears before checking they mesh freely
• Over-tightening axles so parts bind
• Skipping dry-fit and assembling out of order
• Testing with too much force
