Discussion:

Characteristic Properties Vs General Properties

Characteristic Properties: Good for Identification,

Colors, shapes, textures,

General Properties: mass, volume,

This chapter is about identifying the properties of matter and learning how scientists classify matter to help us understand it.

Assign Reading pp.14-21

Go over "Guide for Reading" and

Answer these questions to yourself as you read

What are the three states of matter?

Why are characteristic properties useful?

How can matter be classified?

Go over "Reading Strategies" p. 14K

As students read have them make a list of properties of matter

Objectives: The student will be able to…

Distinguish between chemical and physical changes of matter
Identify characteristic properties of matter and explain their uses
Compare mixtures of pure substances and describe elements and compounds.

Presentation: Properties of Matter

What is Matter? Matter is the stuff that makes up the universe, or it is anything with mass and volume.

(With defintitions, I do not want the words out of the book but for you to be able to explain them.)

What wouldn’t be matter? Anything that doesn’t have mass or volume. Space

What is a property? Anything that can be used to describe or identify a substance.

Think of a property as things such as size shape color odor, weight etc.

Can the properties of matter can change? Some properties can change. When the conditions a substance is under changes the properties may change. For example ice can change to water and water can change to steam.

All substance can change like this they are called The States of Matter and all substances can have solid, liquid, and gas forms.

Characteristic Properties: Characteristic properties are properties that never change. Like the hardness of a diamond, or the density of gold. Because they never change we can use these to identify a substance.

Boiling Point: is a characteistic property. It is the point at which a substance turns form a luquid to a gas. Every liquid has a special temperature that it boils at so we can use that temperature to identify it.

Melting Point: is a characteristic property to help you identify solids. It is the point that a solid turns into a liquid. Every solid has a special temperature that it melts at.

Physical Changes: Melting Point and Boiling point are considered physical changes. The substance is still the same thing and can be changed back to it's original form.

Chemical Changes: but sometimes changes in substance create a new substance like burning a piece of paper. We can't take the ashes and turn it back into paper it has become smoke and heat and ash. We have created a new substance. C+N=CN H + O = H20 Na + Cl = Salt
