through a conductor which makes an electric current.

Front 27

Physical Change

Back 27

a change in the size,shape or state of matter

Front 28

Physical changes do not

Back 28

change the matter to a new substance only chemical substances do that.
Examples: pulling a rubber band, writing on paper with colored chalk, ice cubes melting

Front 29

Heat affects physical changes. When matter gets hotter

Back 29

the particles of matter move FASTER AND FARTHER APART.

Front 30

When matter cools, the particles of matter

Back 30

move slower and pull closer together.

Front 31

When most materials are heated, they ________

Back 31

expand (move apart)
Example: A sidewalk, bridge, or highway expands in hot weather. They will crack if they don't have space between the sections.

Front 32

When most materials are cooled, they ___________

Back 32

contract (come together).

Front 33

There are 2 "rule breakers"

Back 33

1. Water
2. Rubber
Both expand when cooled to a certain temperature.
Example: a can of coke freezing and exploding in the freezer

Front 34

When matter changes _________, an entirely new substance is formed.

Back 34

chemically
Examples: 1. Adding vinegar to baking soda.The new substance is neither vinegar nor baking soda
2. Wood burning-the ashes left have no properties of the original wood; metal rushing

Front 35

Mixture

Back 35

Matter that has 2 or more substances combined.

Front 36

Mixtures can be separated by ________ means.

Back 36

Physical
Examples: iron ore- a mixture of iron and rock. Iron can be separated by grinding to a powder and passing large magnets over the powder to pick up the iron.

Front 37

Air

Back 37

a mixture of gases.

Front 38

Gases can be separated by

Back 38

cooling them and turning them into liquid

Front 39

When liquid air is warmed again each gas will

Back 39

boil and change back to gas at a different temperature. As that gas boils, that gas is collected.

Front 40

Solution

Back 40

a mixture in which the different particles of matter are spread evenly throughout.

Front 41

Solution particles are so evenly divided that you

Back 41

can't see them

Front 60

How does a sponge get food?

Back 60

Sponge animals that are attached to hard surfaces can not move around and hunt for food.
They get their food by filtering the sea water that enters their pores. The water carries tiny bits of food with it. Cells in the sponge trap the food and let the seawater out.
