Curie Notes 01: What Chemistry Studies: Matter, Mixtures and Pure Substances
Five things on my bench in the shed: pitchblende, water, salt, iron and copper. I teach you to say what each one is, and how to take a mixture apart.
Learn the states of matter, physical and chemical change, elements, compounds and mixtures, how to separate a mixture, and how density identifies a substance.
