1
a material that allows energy to pass through it easily.
conductor
a material that slows or stops the flow of energy.
insulator
the amount of matter in an object or substance
mass
anything that has mass and takes up space
matter
a piece of matter that is too small to be seen with the unaided eye.
particle
a combination of two or more different kinds of matter, each of which retains its own physical properties
mixture
to mix evenly to create a special mixture called a solution
(think about the process)
dissolve
method for finding volume of objects with irregular shapes (such as a rock).
water displacement
a science concept that states that matter cannot be made or destroyed, however it can change into a new form
conservation of matter
a physical property that describes whether a substance is attracted to a magnet
magnetism
a characteristic of matter that can be observed, measured or tested
physical property
the states of matter: liquid, solid, and gas
physical states
the density of an object compared to water; this is determined by observing if an object sinks or floats in water
relative density
a physical property that describes whether a substance will dissolve when mixed with water
solubility
able to dissolve in water
soluble
a mixture in which the particles of different kinds of matter are mixed evenly with each other.
solution
a particular type of matter
substance
the amount of space that matter takes up
volume
If an item is less dense than water, it will...
float
If an item is more dense than water, it will...
sink
Is this statement TRUE?
The following items are all thermal conductors:
Keys, Frying pan, Styrofoam, and Wires.
FALSE
Styrofoam is NOT a thermal conductor.
Is this statement TRUE?
These items help separate mixtures:
strainer, coffee filter, magnetism, tweezers.
TRUE
All are helpful items that separate mixtures.
Is this statement TRUE?
Evaporation and boiling are the same.
FALSE
Evaporation and boiling are NOT the same.
Evaporation happens naturally and boiling does not.
Is this statement TRUE?
Substances that dissolve do disappear in the solution.
FALSE
Substances that dissolve do NOT disappear in the solution.
Example: Salt Water
is this statement TRUE?
All solutions are mixtures, but not all mixtures are solutions.
TRUE
