Lessons that are free to use in any classroom, new research, changes to the dataset, and plain-language explainers. Every entry says which subject it belongs to and what you need to know before reading it. Medical information goes stale, so entries are revised when the evidence moves — revised entries show their update date, not just the day they were first published.

A dark card reading "your calculation will be wrong. that is the lesson." — the cover for a free classroom genetics lesson on lactase persistence.

Lesson: the milk mutation

BiologyGeneticsStatisticsSocial studies Age 13+ Intermediate

A free genetics lesson on natural selection, with no equipment needed. The class computes a prediction from real allele frequencies, gets a clean answer, and then finds out it is wrong — because the same solution evolved four separate times in the last few thousand years.

A strip of paper on a dark background with the words "some of you will taste nothing" — the cover for a free classroom genetics lesson.

Lesson: the bitter paper

BiologyGeneticsStatistics Age 13+ Intermediate

A ready-to-run genetics lesson built on the PTC taste test — free to use in any school, college or university. Forty minutes, one paper strip, and the textbook version of the trait turns out to be wrong in a way that is more interesting than the original.
