Mass is

• the amount of matter in an object

• how much space something takes up

• how tightly packed the molecules are in an object

• what determines if something floats or sinks

Volume is

• how much matter is in an object

• how much space an object takes up

• impossible to measure

• how tightly packed the molecules are in an object

Data is

• how you think or feel about something

• a logical guess based on observations

• the one variable you change in an experiment

• measurements and observations collected in an experiment

A procedure is

• how something feels, tastes, looks, sounds and smells
