Absorb
When a liquid soaks into a material.
|
Algae
Any of a large group of mostly aquatic organisms that contain the green pigment chlorophyll but lack veins.
|
Bead
When a liquid sits on top of a material in drops.
|
Condensation
The process by which water vapor changes into liquid water, usually on a surface.
|
Condense
When water vapor touches a cool surface and becomes liquid water.
|
Contract
To get smaller; to take up less space.
|
Cycle
A process or action that repeats itself in the same order over time.
|
Denser
When an object sinks in water, it is denser than water.
|
Dome
The shape a drop of water takes when it is on a flat surface. It is like a flattened hemisphere.
|
Evaporate
When water in a material dries up and goes into the air.
|
Evaporation
The process by which liquid water changes into water vapor.
|
Expand
To get bigger; to take up more space.
|
Float
To stay on the surface of water as a result of being less dense than water.
|
Flow
The movement of liquid over a surface.
|
Freeze
To change from a liquid to a solid state as a result of cooling.
|
Gas
A state of a substance with no definite shape or volume; usually invisible.
|
Glacier
A large mass of ice moving slowly over land.
|
Gravity
The natural force that pulls objects toward each other. On Earth, all objects are pulled toward the center of the Earth.
|
Ice
The solid state of water.
|
Iceberg
A large mass of ice that has become detached from a glacier and floats in the ocean.
|
Less dense
When an object floats in water, it is less dense than water.
|
Liquid
A state of a substance with no definite shape but a definite volume.
|
Melt
To change from a solid to a liquid state as a result of warming.
|
Property
A characteristic of a material or an object, something that you can observe such as color, smell, and taste.
|
Sink
To go under water as a result of being denser than water.
|
Slope
A slanted or tilted surface.
|
Soak
To be absorbed or move into another material.
|
Solid
A state of a substance with a definite shape and volume.
|
Surface area
The area of liquid exposed to or touching the air.
|
Surface tension
The skinlike surface on water (and other liquids) that pulls it together into the smallest possible volume (a sphere).
|
Thermometer
A tool used to measure temperature.
|
Water
A liquid earth material made of hydrogen and oxygen.
|
Water cycle
The sequence of condensation and evaporation of water on Earth, causing clouds and rain and other forms of precipitation.
|
Water vapor
The gaseous state of water.
