Six ways into the same idea — from bedtime story to chalkboard. No order required.

Told like a bedtime story.
For a curious 10-year-old. No jargon. Just a picture in your head.
Stick two LEGO bricks together and you have a bigger LEGO shape. Atoms work the same way. When two or more of them snap together, the new joined-up thing is called a molecule. Water is a molecule made of three atoms — two hydrogens and one oxygen — locked in a little V shape. Sugar is a much bigger one with a lot of carbon. Which atoms join, and in what order, is what makes one substance wet, another sweet, another stretchy or hard or briefly very angry. Chemistry is basically very small LEGO.
§ Strange but true
- 01Water is a tiny boomerang of three atoms — yet it's the strangest, most life-enabling substance known.
- 02Your DNA is a single molecule. Stretched out it would be 2 meters long.
- 03Interstellar clouds contain alcohol, sugars, and amino acids. Space is doing chemistry without us.
