Unit 1

The study of matter , its structure, properties and composition, and the changes that matter undergoes.

So, why do I need to learn about chemistry?

Almost everything we come in contact with is made of materials created or enhanced by chemistry!! Examples… Plastics Clothing Medicine Cosmetics Hygiene Products

Branches of Chemistry Organic Inorganic Physical Analytical Biochemistry Theoretical

So, how does one use chemistry to make discoveries? The Scientific Method!!!

The Scientific Method A logical approach to solving problems by observing and collecting data, formulating hypotheses, testing hypotheses, and formulating theories that are supported by data.
