This document outlines the key concepts and assessment tasks for a unit on the chemistry of the Earth. The three main concepts are exploring humanity's place in space, how rocks are a source of chemicals, and how matter can be classified. The unit will assess students through a space debate, building investigation, mining investigation, and exam. Students are invited to submit questions to the teacher's blog about what they want to learn within this unit on Earth's chemistry.
