The PhysicalThe Chemical
What’s theMatter?
Matter
Make-upMatter Mix
True or False: Changing
the state of matter is a physical change.
True
When a solid changes into a liquid what
process is occurring?
Melting
When a liquid changes
state into a gas, what process is occurring?
Evaporation
Taylor made a legotower made with three
colors of legos. It weighed5 pounds. The yellow
piece and the blue piece both weighed 1.5 lbs. How
much did the red one weigh?
2 pounds
Ryan weighed a glue stick and it weighed 3 lbs.
The cap weighed .5
pounds. How much did the base
weigh?
2.5 pounds
Name two examples of changes of
state.
Melting, freezing, boiling,
condensing, evaporating
What is a physical change?
A physical change is a change that
does not result in a new
substance.
Give two examples of
physical changes.
Physical changes:Ice melting, glass
breaking, wood beingchopped, paperbeing cut, etc.
What are three
physical propertiesof a globe?
Physical properties are anything that
have to do with the globe
itself.
What is a mixture? Give
me two examples
following the definition.
A mixture is two or more substances being combined without being
changed. Ex: trail mix, salad, salt
water, sand, etc.
What is a chemical property?
A chemical property is a property that involves how a
substance interacts with other
substances.
Name onechemical property
of the elementIron.
Iron reacts withoxygen and water
to form rust.
What is a chemical change?
A chemical change is a change that
results in one or more new substances.
Which state of matter is most dense?
Solid, liquid, or gas.
The particles in a solid are more tightly
packed than both a liquid and a solid.
Give me threeexamples of chemical
changes.
Chemical changes ex: an egg cooking,
cake baking, fireworks, tarnish,
rust, etc.
What is density?
Density is how closelypacked the particlesare in a substance.
What aretwo clues to help
you know whethera chemical
reaction has occurred?
Clues include a change in color,
smell, a new physical property is created, there is a substance
given off, or heat.
What type of change is
demonstrated by each picture
shown?
What are two
experiments that we
did that demonstrated
chemical changes?
Examples will vary.
What is the difference
between the particles that
make up a solid, a liquid, and a
gas?
The particles in a solid are locked in
place, in a liquid they are flowing freely,
and in a gas they are far apart and moving
quickly.
What are the three states of matter?
Solid, liquid, and gas
What is the difference
between weight and
mass?
Weight changes withthe pull of the gravity.Mass is the amount ofmatter in a substanceand never changes.
Which of the following isa physical change?-shredding paper-striking a match
-iron rusting-egg cooking
Shredding paper is a physical change.
Which of the following is a
chemical change?-breaking glass
-water evaporating-bread baking
-wood being chopped
Bread baking is a chemical change.
What is the definition of matter?
Matter is anything that has mass or takes up
space.
