Words highlighted in yellow may be on the retest.


matter

Anything that has mass and takes up space

mass

The amount of matter(stuff) something has in it. 

volume

The amount of space matter takes up

weight

The measure of the force of gravity between an object and the Earth

property

 

Characteristics of something; words we use describe something/matter

width

How wide an object is

height

How tall something is

length

How long something is

density

A way of describing matter in which you tell how massive something is for its size- how much "stuff " is tightly packed into it. 

buoyancy

An object's ability to float

graduated cylinder

A tall, thin container used to measure the volume of liquids

beaker

 

Shorter, fatter (than graduated cylinders) cylindrical containers used to measure the volume of liquids

measuring cup

 

Cups with markings to measure the volume of liquids most commonly used in kitchen for baking or cooking purposes.

liters/milliliters

Metric units for measuring the volume of liquids

balance scale

A tool used to measure the mass of an object

grams/kilograms

metric units used to measure mass

meters/centimeters

metric units used to measure length/height/width

element

 

a pure compound that cannot be broken down into any simpler substance

compound

 

substance formed by a chemical combination of two or more elements and acts like a single substance

atom

 

The smallest unit of an element that keeps the properties of that element

proton

a part of the atom that carries one unit of positive electric charges

neutron

a part of the nucleus of an atom that has no net electric charge

electron

a part of the atom that carries one unit of negative electric charges

nucleus

an atom's center where most of its mass is located

molecule

a particle that contains more than one atom joined together

chemical change

a change that results in the formation of new chemical substances

physical change

a change that doesn't really change the matter in an object

conduct/conductor

to conduct means to allow energy to flow through/a conductor is a material that allows energy to flow more easily

Insulate/insulator

 

to prevent energy from moving freely/an insulator is a material that prevents energy from moving freely

  

 Vocabulary from Energy

conduction- the transfer of heat through a material by direct contact

convection- the transfer of heat in a gas or liquid state as a result of the movement of the gas or liquid (think convection cell)

radiation- the transfer of heat by electromagnetic waves

temperature- the measurement of heat

insulator- something that slows the transfer of heat
