Characteristic Properties of Substances

Physical Properties of Matter

Investigation 1.1

What is Matter?

• Anything made of particles. 

• It has mass and volume (takes up space).

• Matter can be in the form of a solid, liquid, or gas.

Multiple Choice

What is matter?

• Everything

• Nothing

• Nothing you can see

• Just liquids

Physical Properties

• Can be observed with one or more of your 5 senses.

• Can be observed without changing what the object is made of.

• 
  

Color

How an object absorbs and reflects light.

Multiple Choice

Physical Properties

• Can't be observed unless you change what they are made of.

• Can only be observed under a microscope

• describe the appearance of something.

• Can only be done in science.

Ductility

The ability of a substance to be made into a wire

Multiple Choice

What are the 3 forms of matter?

• solid, liquid, soil

• solid, liquid, gas

• Earth, Wind, Fire

• Fire, Water, Soil

Texture

• How a substance looks and feels

• Coarse = rough

• Fine = smooth

• Other words to describe texture: soft, hard bumpy

Temperature

The measure of kinetic energy.

When the particles of heated up, they move quicker and temperature rises.

When the particles are cooled down, they move slower and the temperature decreases.

Multiple Choice

What is texture?

• How something looks

• How something tastes.

• The sound something makes

• How something feels

Volume

• The amount of space an object takes up.

• Measured in cubic centimeters

Mass

How much matter is in an object

Measured in g or kg.

Multiple Choice

What does volume measure?

• mass

• the size of something

• how much space something takes up.

• the speed something goes

Density

• The ratio of mass to volume.

• Measures how packed the particles are in matter.

Size

How big something is

Multiple Choice

What does density measure?

• Nothing

• How much volume something has

• how packed particles are in a substance.

• the temperature of an object.

Luster

• How way an object reflects light.

• How shiny it is

• Words that describe luster: shiny, metallic, dull, pearly, glassy

Malleability

The ability to be hammered flat and keep its shape.

Multiple Choice

If I observe an object and describe it as shiny and metallic, I am describing

• luster

• ductility

• texture

• malleability
