Cset Multiple Subject: Science

Front 1

What is Physical Science?

Back 1

Physical science are the branches of natural sciences that study:

-the nature

-properties of energy

-non-living matter

Front 2

What is Matter?

Back 2

Matter is anything that has volume and mass.

Front 3

States of Matter

Back 3

Solids, Liquids, and gases

Front 4

Solids

Back 4

Solids, like your desk, your backpack and your pants, are firm and stable. Their molecules are grouped together in organized patterns. The molecules might vibrate slightly, but they don’t move around.

Front 5

Liquids

Back 5

Liquids, like water, oil and soda, shift to fit inside the container they’re in. If you look at them under a microscope, you’ll see that they have particles that are close together, but have no rhyme or reason. The molecules move around.

Front 6

Gases

Back 6

Gases, including air, steam and helium, are free-flowing. You can easily put your hand through them. Gases shift to fit their container and can even fill it. Their molecules are spaced far apart and wiggle and jiggle.

*Vapor and gas mean the same thing.

Front 7

Sublimation

Back 7

Transition from a solid to a gas phase without becoming a liquid.

EX: a block of dry ice (CO2) which will turn into a gas at room temperature.

Front 8

Desposition

Back 8

Transition from a gas to a solid without becoming a liquid.

EX: Some gases can transition directly to a solid, such as the formation of frost.

Front 13

Mass

Back 13

Mass is the amount of a matter in an object. (weight)

Example:

- Elephant = a lot of matter = LARGE mass

- Paper clip = a small amount of matter = SMALL mass
