Matter:
Properties and
Change
Matter
 Anything that takes up space and has mass
Law of Conservation of Matter
 Matter can not be created or destroyed
 These legos weigh the same when they are together
and taken apart
qualitative
 Information collected and communicated in words
 Observable by using your senses
 Example: color, shape, odor
quantitative
 Exact information about the quality you observe using
numbers rather than words.
 Example: length, weight, volume, temperature
weight
 Measure of the pull of gravity on an object
States of Matter
Solid-definite
volume; doesn’t
change
Liquid-a definite
volume but no shape
Gas- no definite
volume or shape
Plasma
 Boiling Point – The temperature at which liquid matter
experiences the same pressure as the atmospheric
pressure; turns to a gas
 Freezing Point – The temperature at which liquid
matter turns to solid.
 Melting Point – The temperature at which solid matter
turns to liquid.
Physical Properties of Matter
Observable characteristics
that can change without
changing their chemical
composition
Example: color, form or
shape
Physical Change
Changes in shape, size or physical
state (phase) of matter
Example: Shredding paper, cutting
up fruit, freezing water, boiling
water
Chemical Properties of Matter
 Properties of a substance that when changed, result in
a new substance
 Example: ability to conduct heat; reactivity with other
substances (rust)
 These properties create chemical changes in a
substance
Chemical Change
A change in matter that produces new substances
Examples:
Ability to burn
 Wood to ash
Ability to rust/ react with oxygen
 Metal to rust
Ability to form a new substance with chemical
composition different than the original substance.
 Digestion of food
