Properties of Matter

Mrs. Garner’s5th Grade Science Class

Atoms are the smallest part of an

element; the building blocks of matter.

Atoms

Matter is anything that has

mass and takes up space.

Matter

Molecules are particles that are

made up of two or more atoms of the same or different elements.

Molecules

The three typical forms of matter are:

solids, liquids, and gases; the states of water are: ice (solid), liquid water, and vapor (steam)

States of Matter

Solids- state of matter with a definite shape and

volume

Liquids- state of matter with a definite volume but no

definite shape; Liquids take the shape of their container!

Gases- state of matter with no definite volume or

shape; examples: water vapor; steam

Evaporate: the changing of a liquid to a gas

Defining the States of Matter: Solids, Liquids, and Gases

States of water can change when a change of temperature is involved.

Increase the Temperature--- solid to a liquid & liquid to a

gas

Decrease the Temperature----gas to a liquid & liquid to a solid

Color, size, shape, and the texture

(the way it feels) are the properties or characteristics of matter.

Properties of Matter

** Color

** Luster (shine)

**Shape

**Density (Mass)

** Texture (how it feels)

Physical Properties of a Substance

Sometimes matter is too small

to be seen without magnification.

Microscopes and Hand Lenses

the amount of matter in an object how heavy something is without

gravity measured in grams

Mass

Weight is the measure of the

pull of gravity on an object.

Weight

Comparing Mass & Weight

Mass -the measure of

the amount of matter in an object

Weight - the measure of the

pull of gravity on an object

Volume is the amount of space

that matter takes up.

Volume

-the science that deals with the

characteristics of elements, the changes that take place to form substances, and the laws of their behavior

Chemistry

Matter Can Undergo Two Different Types of Changes

Physical Change

Chemical Change

-the shape or form of a substance becomes

different, but the properties of the substance stays the same; it’s a change in the size, shape, or state of matter that does NOT CREATE A NEW KIND OF MATTER;

-Example- changing water into ice, or ice melting into water, water boiling into a vapor

Physical Change

-a change in matter that produces new kinds

of matter with different properties; atoms are arranged into new molecules

-Examples- Burning, rusting, explosions, acid

Chemical Change

A chemical reaction happens when

two or molecules interact and something happens or changes.

Chemical Reaction

Clues That a Chemical Change Has Taken Place :

Change in : color, temperature,

odor

Bubbles or Fizzing

Burning or Rusting

Measurement is finding a number that shows

the size or amount of something. There are two main “Systems of

Measurement”: Metric and US Standard.

Measurement

The metric system is a system measurement

that uses multiples of 10.

Length: 1 cm= 10 mm, 1 m= 100 cm, 1 km= 1,000 m

Volume: 1 L= 1,000 mL

Mass: 1 kg = 1,000 g
