Unit One: Matter

Part One: Matter Objective: To learn what matter is

Part One: What is Matter Matter is anything that has mass and takes up space

Part Two: The Atomic Nature of Matter Objective: to understand that matter is composed of atoms

Matter is made up of atoms Scanning Tunneling Microscope gives us the chance to see atoms Atoms are like sand on a beach

Part Three: Elements and Compounds Atom- tiny particle that makes up matter Contains: Negative Electrons Positive Protons (in nucleus) Neutral Neutrons (in nucleus)

Part Three: The States of Matter Objective: To define the three states of matter

The States of Matter A SOLID is rigid and has a fixed shape and volume

The States of Matter A LIQUID is fluid, has a definite volume, but takes up the shape/space of its container

The States of Matter A GAS has no fixed volume or shape. It uniformly fills any container

The States of Matter

What state am I? I am matter that loves to take the space of whatever I’m in. I’m often invisible and very full of energy.

What state am I? Some people call me a moderate. I am flexible enough to take the shape of my container, though my volume never changes

What state am I? I am never changing, I keep my shape no matter what I’m stuck in. Some people say I’m cold.

Part 4: Kinetic Theory of Matter Objective: To understand that molecules are always moving and how we measure temperature

Kinetic Theory of Matter Molecules are always moving. This is the Kinetic theory of matter. Movement of molecules uses energy. The more energy something has, the faster it moves.

Temperature Heat is the energy that flows between objects of different temperatures. We measure kinetic energy with a thermometer and call it temperature. The warmer it is, the faster air molecules are moving.

Part Five: Phase Changes of Matter Objectives: Understand how energy changes the state of matter, understand how to graph and read phase change graphs

Energy and phase changes As energy is added or released from molecules, the substance changes phases

Vocabulary Terms When Energy is added: Solids MELT into liquid Liquids EVAPORATE into gas Solids SUBLIME into gas

Vocabulary Terms When Energy is lost: Gas CONDENSATES into liquid Liquid FREEZES into solid Gas DEPOSITES into solid
