Mass, Volume, Weight, Length

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

triple 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 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 controlled variable

a variable that you have to keep the same so that you test only 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
