Introduction to the Three Perspectives00:00:01

Introduction to using graphite as a model to understand chemistry through three lenses: macroscopic observations, particle-level structure, and chemical symbols.

Macroscopic Perspective00:02:32

Analyzing graphite's observable characteristics, such as color, brittleness, and density, while explaining how to quantify these traits through measurement and counting.

Particle-Level and Symbolic Perspectives00:04:01

Examining how carbon atoms form sheets in graphite and identifying how symbolic notation distinguishes different allotropes like graphite and diamond.

Physical Properties and Changes00:06:25

Defining physical properties and changes, using the example of snapping a piece of graphite or mixing it with other materials to demonstrate changes that do not alter the chemical composition.
