This is a 6th grade unit written to help students understand the abstract concept of atoms. Students will learn about the history of atomic theory and examine contemporary theories of atomic structure. The next piece is to explore the Periodic Table of Elements and gain an understanding for how it is organized. The culminating performance task invites students to adopt an element and create a 3 dimensional model of their specific element in addition to a written component.
