VOCABULARY
balance- a tool used to measure
mass buoyancy- a
force in fluids that opposes the force of
gravity capacity-
the amount that can be held by a container cargo- the
total amount of weight that is carried on a boat density- a
property of matter that is a measurement of the
amount of mass per unit volume of the substance;
the more tightly packed the particles within a
substance are, the more dense it is displacement-
one object moves out of the way to make room for
another float- when
part or all of a material is above the surface
of a liquid fluids- a
substance-either gas or liquid-that flows and
exerts a buoyant force on objects placed in it force- a
push or a pull gravity- the
tendency for large objects to attract other
objects; gravity on earth results in objects
being pulled towards the earth length- the
property of matter that can be measured with a
ruler mass- the
amount of material in an object; a property of
matter that can be measured with a balance prediction-what
you think will happen in the future properties-
the qualities used to describe objects such as
size, color and shape sink- when
no part of an object is above the surface of a
liquid surface area-
the amount of space on the outside of an object,
measured in square units volume- the amount of space an
object takes up; a property of matter that is
measured in different ways. Water
displacement can be used to measure the volume
of a solid weight- a
measurement of the force of gravity on an
object; a property of matter that changes
depending on the location of the object and the
amount of gravity acting on it.
