How a five-class STEM month runs in school

What happens in each class of a monthly cohort, and why every student ends the month by explaining their own build.

Our school cohorts run five classes a month for batches of 15 to 25 learners. Classes last 60 to 90 minutes depending on age. Every class follows the same rhythm, so students always know what comes next.

Teach, build, test, explain

  1. Teach: a short, hands-on lesson on one idea
  2. Build: small groups put it together with low-voltage kits
  3. Test: groups check it, write down what failed, and fix it
  4. Explain: each student tells the class what they built and why it works

Matched to each age group

Class 6–8 students start with logic, block coding and simple circuits. Class 9–10 move to Python, sensors and data. Class 11–12 work on machine learning basics, robotics and a tested prototype.

Safe by default

We only use low-voltage kits, and a teacher from the school stays in every class. Instructors check circuits before they are powered on.

What the school gets

At the end of each month, students show their builds and the school receives attendance and assessment records. Many schools start with one pilot cohort before deciding on anything bigger.
