Website
Say it like this
A place on the internet where somebody keeps their things so other people can come and look.
For the grown-up
A website is a collection of pages served from a specific address. Somebody built it, chose what goes on it, and decided what you see first. None of it arrived by accident.
The easy mistake
Careful here. Somebody made this, on purpose, for a reason. That single sentence is the root of media literacy and it is far easier to plant at five as a fact about places than at fifteen as a warning.
The full explanation

A glossary entry is the short version. This one has the child explanation, the grown-up explanation, the questions and an activity.
