For families — the Dinner Table Question
Every lab ends with one question to ask at home. No answer key, no grade — just a conversation.
Lab 5: Imagine a new disease appeared that killed only dark-colored moths in your neighborhood. What would the moth population look like in 20 years — and what principle explains that change?
En español: Imagina que apareciera una nueva enfermedad que matara solo a las polillas de color oscuro en tu vecindario. ¿Cómo se vería la población de polillas en 20 años — y qué principio explica ese cambio?
