5thGr-Matter/Energy 5th Grade Science Test: Matter/Energy Test 2012

Flashcard maker : Lily Taylor
Question Answer
Matter Anything that has mass and takes up space
Mass The amount of matter in an object
Properties Appearances of an object including: mass, magnetism, physical state, relative density, solubility, and the ability to insulate or conduct heat or electricity
Magnetism The property of attraction to a magnet
Physical State The classification of matter as a solid, a liquid, or a gas
Relative Density Objects that are more dense sink in water; less dense objects float in water
Solubility Measurement of the ability of a solid to dissolve in a liquid
Thermal Energy Energy that causes a change in temperature between materials
Electrical Energy Energy produced by the movement of electrons
Conductor Material that allows electric current or heat energy to flow through easily
Insulator Material that slows down or stops electric current or heat from flowing
Classify Group together based on similar traits
Constant Not changing; the same
Boiling Point The temperature at which a substance changes states from a liquid to a gas (the boiling point of water is 100 degrees Celsius or 212 degrees F)
Melting Point The temperature at which a substance changes states from a solid to a liquid
Freezing Point The temperature at which a substance changes states from a liquid to a solid (freezing point of water is 0 degrees Celsius or 32 degrees F)
Condensation Physical change in matter from a gas to a liquid
Evaporation Physical change in matter from a liquid to a gas.
Water has definite shape and volume in the solid state
The triple beam balance is measured in grams
The triple beam balance has 3 riders: they are the hundreds, tens and ones
To find mass of a liquid, you must first measure the container by itself
The gas state of matter consists of spread-out particles in no particular pattern
The liquid state of matter consists of tighter-knit particles in no particular pattern
The solid state of matter consists of very close-knit particles in a definite pattern
Water has a definite shape and volume in the solid state
Matter can be classified based on its physical properties using tools such as triple beam balances, magnets, or electrical circuits
Matter can be classified based on its behavior such as if it will sink or float in water, attract to magnets, if it is soluble in water, or conduct heat or electricity.
We can identify the boiling and freezing/melting points of water using a thermometer
