Matter: Anything that has mass and takes up space; the substance of which a physical object is made up of
Mass: Describes how much matter is in an object
Weight: The measure of the pull of gravity on an object
Volume: The space an object takes up
Molecule: The smallest particle of a substance having all the characteristics of the substance
Solid: Something that has matter and takes up a definite amount of space. It has a definite shape.
Liquid: Something that has matter, but takes the shape of its container.
Gas: Something that has matter but does not take up a definite amount of space. It does not have a definite shape.
Water Cycle: Continuous movement of water between Earth’s surface and the air, changing from liquid to gas to liquid
Evaporation: When a liquid is changing into a gas (vapor) as it is heated.
Condensation: When a gas is changing back into a liquid as it cools
Precipitation: Water that falls to the earth in the form of rain, snow, sleet, hail, or mist
