Mass
The amount of matter in an object.
Volume
The amount of space an object takes up
Density
The measurement of how tightly packed particles are in an object
Weight
The force of gravity on an object
Grams
SI unit for Mass
liters
SI unit for liquid volume
meters
SI unit for length
cubic centimeters
SI metric unit used to measure volume
Newtons
SI unit for weight
tripel beam balance
the tool used to measure mass
graduated cylinder
the tool to measure the volume of a liquid
water displacement method
the method to measure irregular shaped solids
meniscus
the curved line formed when water is in the graduated cylinder
meter stick
tool to measure length
grams
unit to measure mass
how do you find the mass of a solid
with a triple beam balance
what is a graduated cylinder
the tool to measure liquids
what units are used to measure mass
grams are the unit to measure mass
what are the units to measure volume of solids
cubic centimeters
how do you find the volume of a regular object
you use the formula l x w x h
how do you find the mass of a solid
you use a triple beam balance
how do you find the volume of an irregular object
you use the displacement method
why is the mass of an object constant
the matter that the object is made of does not change
why does weight change in location
weight changes in location because weight is an object’s mass multiplied by the gravitational pull on an object
what is the formula for density
mass divided by volume = density
what is the density of water
the density of water is 1 g/mL
why does an object sink
if the objects density is higher than the water then it will sink
why does an object float
if an object floats then it means its density is lower than the liquid
what is a control variable
something you have to keep the same so that you test what you are testing
what is an independent variable
the variable you are changing purposely
what is a dependent variable
the variable that changes because of the test
