Match the following terms with their correct definitions.

• Mass - the amount of matter in an object

• matter - makes up all objects and substances in the universe

• volume - the amount of space that an object or substance takes up

• graduated cylinder - instrument used to measure the volume of a liquid or an irregular shaped object.

• triple beam balance - instrument used to measure mass.
