Each learning path is one chapter: a guided route through a topic, one small course at a time. Pick a class to see its chapters in order.
A potato sprouts new plants from its eyes, a Hydra grows a bud that breaks away, and a flower turns into a fruit full of seeds. Living things make more of their own kind in many ways.

Python helps you count how fast a population of cells can grow.
