Constant
When an object stays the same and does not change over time.
Attribute/Characteristics
Property of an object such as size, shape, color, texture, and weight.
Graduated Cylinder

States of Matter
Solid, Liquid, and Gas
Can Matter change from one state to another?
Yes
Solid
The state of matter that holds its own shape and has volume.
Liquid
The state of matter that changes its shape according to the container it is in. Liquids have volume.
Examples of Liquid
water, juice, soda or syrup
Examples of Solid
rock, sand, chunk of metal, or a block
Gas
The state of matter that expands to fill the container.
Examples of Gas
water vapor, helium, oxygen
Melts
When ice turns to water
Freezes
when water turns to ice
Heat Energy
Changes in the state of matter from solid to liquid to gas require this form of heat.
Evaporation
When a liquid changes into a gas
Condensation
When a gas changes back into a liquid.
When does Condensation occur?
when the surface temperature of an object is colder than the air.
What are Magnets made from?
Lodestone (magnetite) - natural and man made
Magnetic Poles
North and South poles
Which poles are attracted to each other?
Unlike Poles
Which poles repel each other?
Like Poles
