STEM & engineering classes · Ages 4–14

Big ideas start with little builders.

At Gadgetfactory, children design, build and test real engineering projects — robots, bridges, circuits and more — guided by mentors who make learning feel like play.

  • Small classes — max 10 kids
  • Background-checked STEM mentors
  • All kits & materials included

Our programs

Three paths, one goal: kids who love to build

Every program is hands-on from minute one, grouped by age and led by a trained STEM mentor.

Junior Builders

Ages 4–6

First steps into how things work

Big blocks, simple machines and playful challenges. Little engineers stack, snap, roll and ramp their way to understanding levers, wheels and balance — no screens, all hands.

  • Block bridges & towers
  • Ramps and marble runs
  • Pulleys and lever toys

Robo Makers

Ages 7–10

Robots, gears and first code

Kids assemble real wheeled robots, wire up motors and sensors, then bring them to life with friendly block-based coding. Every class ends with a challenge bots must solve.

  • Gear-driven rovers
  • Line-following sensor bots
  • Sumo-bot showdowns

Young Engineers

Ages 11–14

Real design, real problem solving

Older students take on genuine engineering briefs — bridges that hold weight, cranes that lift, circuits that sense. They sketch, prototype, test and iterate like a real design team.

  • Load-bearing bridge builds
  • Working crane & lift models
  • Arduino sensor projects

Age groups

The right challenge for every age

4–6

Little Tinkerers

Motor skills, cause & effect, and the joy of building through guided play.

7–9

Junior Engineers

Simple machines, structures and teamwork on week-long build projects.

10–12

Robo Inventors

Robotics, sensors and block coding wrapped in friendly competitions.

13–14

Teen Makers

Engineering design briefs, Arduino electronics and portfolio projects.

Curriculum

How real engineers think, taught step by step

Every class follows the engineering design process — the same loop professionals use — scaled to small hands and big imaginations.

  • Structural engineering
  • Robotics & mechanics
  • Block-based coding
  • Circuits & electronics
  • 3D thinking & sketching
  • Teamwork & presentation
  1. 01

    Ask

    Every project starts with a real question: how strong can a paper bridge be? How does a robot see a line?

  2. 02

    Imagine

    Kids brainstorm wild ideas out loud — no wrong answers, just possibilities sketched on whiteboards.

  3. 03

    Plan

    Teams pick a direction, draw their design and divide up the parts, learning to commit to a plan.

  4. 04

    Build

    Hands on tools, kits and materials. Mentors coach technique but never take over the build.

  5. 05

    Test

    Weight tests, race tracks and obstacle courses. Failing here is the fun part — data, not defeat.

  6. 06

    Improve

    Back to the bench to iterate. Kids learn that engineers never stop at version one.
