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.
