Matter Vocabulary Words
* Matter - anything that has mass and takes up space.
*Physical Properties of Matter - things that you can observe or measure without changing the matter into something new.
*Three Phases of Matter - 1. Solid 2. Liquid 3. Gas
- Also called "The 3 Forms of Matter" or "The 3 States of Matter"
- We learned that matter stays the same amount when it changes state. No
matter is gained or lost. It stays the same amount.
*Melting - when a solid turns into a liquid
- add thermal energy
*Freezing - when a liquid turns into a solid
- take away thermal energy
*Evaporation - when a liquid turns into a gas
- add thermal energy
*Condensation - when a gas turns into a liquid
- take away thermal energy
* Mass - measures the amount of mass in an object
- scientist use an istrument called a balance to find
- stays the same on the moon
* Weight - measures the pull of gravity
- is less on the moon.
*Metric System - The measuring system used by the rest of the world and used by all scientist.
meter - measures length or distance
gram - measures mass
liter - measures liquid volume
*Volume - the amount of space something takes up
- find volume of a regular solid with length x width x height
- find volume of a liquid with a graduated cylinder (get eye level and read the bottom of the
meniscus)
- find the volume of an irregular solid with water displacement
*Density - The amount of mass in a certain volume (basically the amount of matter in a certain space)
- LESS density = FLOATS
- MORE density = SINKS
*Physical Change - a change that does not make anything new.
- a change of size, shape, or state
- For example, melting a piece of chocolate. You changed the chocolate becuase you
melted it causing it to change from a solid to a liquid but it is still just a piece of
chocolate. You did make anything new.
- Another example, cutting a carrot. You cange the shape and size of the carrot but it is
still just a carrot. Nothing new was made.
*Chemical Change - a change that makes something new.
- The new substance has new properties.
- CANNOT be reversed
- Example, rust forming on a nail. The new substance - Rust - was made.
Chemical Change Clues
* These mean a chemical change MIGHT be occuring
- change in color
- change in temperature
- new smell
- bubbles
- flame
- smoke
