Properties of Matter
Mrs. Garner’s5th Grade Science Class
![Page 2: Mrs. Garner’s 5 th Grade Science Class. Atoms are the smallest part of an element; the building blocks of matter. Atoms.](https://reader036.fdocuments.in/reader036/viewer/2022062308/56649e0a5503460f94af21cf/html5/thumbnails/2.jpg)
Atoms are the smallest part of an
element; the building blocks of matter.
Atoms

Matter is anything that has
mass and takes up space.

Molecules are particles that are
made up of two or more atoms of the same or different elements.

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
![Page 6: Mrs. Garner’s 5 th Grade Science Class. Atoms are the smallest part of an element; the building blocks of matter. Atoms.](https://reader036.fdocuments.in/reader036/viewer/2022062308/56649e0a5503460f94af21cf/html5/thumbnails/6.jpg)
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
![Page 7: Mrs. Garner’s 5 th Grade Science Class. Atoms are the smallest part of an element; the building blocks of matter. Atoms.](https://reader036.fdocuments.in/reader036/viewer/2022062308/56649e0a5503460f94af21cf/html5/thumbnails/7.jpg)
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.

**Density (Mass)
** Texture (how it feels)
Physical Properties of a Substance
![Page 10: Mrs. Garner’s 5 th Grade Science Class. Atoms are the smallest part of an element; the building blocks of matter. Atoms.](https://reader036.fdocuments.in/reader036/viewer/2022062308/56649e0a5503460f94af21cf/html5/thumbnails/10.jpg)
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
![Page 12: Mrs. Garner’s 5 th Grade Science Class. Atoms are the smallest part of an element; the building blocks of matter. Atoms.](https://reader036.fdocuments.in/reader036/viewer/2022062308/56649e0a5503460f94af21cf/html5/thumbnails/12.jpg)
Weight is the measure of the
pull of gravity on an object.
Weight
![Page 13: Mrs. Garner’s 5 th Grade Science Class. Atoms are the smallest part of an element; the building blocks of matter. Atoms.](https://reader036.fdocuments.in/reader036/viewer/2022062308/56649e0a5503460f94af21cf/html5/thumbnails/13.jpg)
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
![Page 14: Mrs. Garner’s 5 th Grade Science Class. Atoms are the smallest part of an element; the building blocks of matter. Atoms.](https://reader036.fdocuments.in/reader036/viewer/2022062308/56649e0a5503460f94af21cf/html5/thumbnails/14.jpg)
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
![Page 16: Mrs. Garner’s 5 th Grade Science Class. Atoms are the smallest part of an element; the building blocks of matter. Atoms.](https://reader036.fdocuments.in/reader036/viewer/2022062308/56649e0a5503460f94af21cf/html5/thumbnails/16.jpg)
Matter Can Undergo Two Different Types of Changes
Physical Change
Chemical Change
![Page 17: Mrs. Garner’s 5 th Grade Science Class. Atoms are the smallest part of an element; the building blocks of matter. Atoms.](https://reader036.fdocuments.in/reader036/viewer/2022062308/56649e0a5503460f94af21cf/html5/thumbnails/17.jpg)
-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
![Page 18: Mrs. Garner’s 5 th Grade Science Class. Atoms are the smallest part of an element; the building blocks of matter. Atoms.](https://reader036.fdocuments.in/reader036/viewer/2022062308/56649e0a5503460f94af21cf/html5/thumbnails/18.jpg)
-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
![Page 19: Mrs. Garner’s 5 th Grade Science Class. Atoms are the smallest part of an element; the building blocks of matter. Atoms.](https://reader036.fdocuments.in/reader036/viewer/2022062308/56649e0a5503460f94af21cf/html5/thumbnails/19.jpg)
A chemical reaction happens when
two or molecules interact and something happens or changes.
Chemical Reaction
![Page 20: Mrs. Garner’s 5 th Grade Science Class. Atoms are the smallest part of an element; the building blocks of matter. Atoms.](https://reader036.fdocuments.in/reader036/viewer/2022062308/56649e0a5503460f94af21cf/html5/thumbnails/20.jpg)
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.

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
