Try it yourself
These two modules are our most complete. Each opens in the regular student view — the same guided tabs a student works through, read-only so you can explore without an account.
Design and build a car powered only by the air escaping from a balloon.
Design and build a bridge using only popsicle sticks and glue that can hold the most weight.
Design a device that helps with a real classroom problem. Practice empathy, constraints, prototyping, and iteration.
Build a section of a chain reaction that triggers the next group. Practice planning, reliability testing, and documentation.
Build a rover that can drive and complete a task. Learn systems thinking, debugging, and power management.
Create a wearable micro:bit project: scrolling message, mood meter, step counter, or timer with a custom case.
