Includes a digital, downloadable guide for Classical Conversations Cycle 1 lessons for Week 20.
CC Cycle 1 Week 20 Lesson: Crust, Mantle, and Core explores the structure of the Earth and how scientists learn about its interior without ever traveling to its center. In this lesson, students examine four key types of evidence—gravity, so-called “alien” rocks, magnetism, and earthquakes—to understand what lies beneath the Earth’s surface within the Classical Conversations Cycle 1 curriculum.
This lesson supports hands-on investigation, scientific reasoning, and classical inquiry, guiding students to think critically about evidence while engaging in meaningful discussion about Earth’s design.
