What's there#

Section	What you'll find
Topics (opens another site)	A catalogue you can search and filter by Subject, Age (from Ages 4 to 5 to Ages 12 to 14) and Type (Concept, Method, Representation, Language or Thinking skill)
Labs (opens another site)	Interactive lessons, each built around a real object or system that works

A lab plays as a short film you can pause and scrub, then hands you the controls so you can try it yourself. Every lab sits on the topic it teaches.

Lab	What you do
Balance 3x + 5 = 20 (opens another site)	On a 3D balance, take the same from both sides until x stands alone
Why an LED needs a resistor (opens another site)	On a drawn circuit bench, turn up the voltage and see what too much current does
Find the slowest step (opens another site)	In a live bakery line, add a machine and watch the bottleneck move

Learn works in light and dark, on a phone or a big screen. Share a lab's address to send someone straight to it.
