Who it is for
The lessons are for anyone curious about the molecules in and around them. If you know that everything is made of atoms, you are ready to start.
How the lessons work
There are thirty short lessons, in six sets of five. Each one is split into small sections, with a drawing or a 3D model for every new idea and a quick question at the end so you can check what stuck. Do them in order: each lesson uses ideas from the one before. The homepage shows the first five, then the next five each time you finish a set, and the lessons page shows how far through the course you are.
For teachers and parents
For teachers and parents lists each lesson with its time and what it covers, ways to use the lessons with a class or at home, and a ready citation.
Why the name?
The bond between two carbon atoms is the backbone of organic chemistry. Carbon atoms can join to each other in long chains, branches and rings, and that is why there are millions of different carbon compounds.
