The Earth's Iron Core

Recently FIELDGUIDES was asked a question by the 8th grade students of Dayton Early College Academy about how we know what the earth's core is made of. FIELDGUIDES created this short video to explain the three main ways we know the earth's core is largely made of Iron alloy. If you have any science related questions for your school or classroom please feel free to contact FIELDGUIDES and we will do our best to answer your questions.
