How I use LEGO Technic to teach my kids real engineering

I'm a mechanical engineer and I've been using LEGO Technic sets to teach my three kids (ages 8, 11, and 14) real engineering concepts. We started with the simpler sets — gear ratios with the small cars, then moved to differential gears with the larger car models. My 14-year-old just finished the Lamborghini Sián (42115) and can now explain how a sequential gearbox works better than some of my college students. The beauty of Technic is that everything is visible — you can see exactly how the gears mesh and transfer motion. I've started a small after-school LEGO engineering club at their school. Best parenting decision I ever made.

This is exactly what LEGO Technic was designed for. The Expert Builder line (as it was originally called) was always meant to teach real-world mechanical concepts. Your approach of starting with simple gear ratios and building up to complex transmissions is exactly the right pedagogical order. If you haven't already, check out the Liebherr crane sets — they're the best for teaching about hydraulics and structural engineering.
