Archean Eon Timeline Second Great Lesson Earth History 5 Part Cards

With a focus on the Archean Eon (approximately 4 billion to 2.5 billion years ago), students will embark on a journey through time, learning about the formation of the first continents, the emergence of early life, and the conditions that shaped our planet’s early environment.

This resource builds vocabulary, chronological understanding, and a deep appreciation for Earth’s history.
