States of Matter Day 1

Unit 1 – Matter

SubUnit - 2

Vocabulary

solid

liquid

gas

melting

vaporization

sublimation

deposition

phase change

Kinetic Energy

Standard

Differentiate among the four states of matter. (Note that there are currently five states of matter that have been identified.)

Objectives

1. Describe the four states of matter, including shape, volume, and motion of molecules.

2. Identify energy differences between and phase changes among the three common states of matter (solids, liquids, gases).

3. Describe all the possible phase changes including behavior of particles before, during, and after a phase change.

SubUnit - 2

Vocabulary

1. heterogeneous

2. homogeneous

3. mixture

4. suspension

5. colloid

6. solutions

7. pure substances

Objectives

1. Graph the heating curve of water.

2. Identify the properties of homogeneous and heterogeneous mixtures.

Heating Curve of Water

Mixture

Homogenous: Uniform Heterogenous: Not Uniform

Contains components in different phases.

All components are in a single phase.

Pure Substances

Elements: Periodic Table Compounds: Multiple Elements

Will eventually settle causing the Tyndall effect to stop
