DENSITY is the amount of
MASS
contained in a given
VOLUME
of some
material.
The following boxes are the
same volume
. Assume all the balls have
Equal
mass.
Which box is more dense?
The following boxes are the
same volume
. Assume all the balls have
Equal
mass.
The box on the LEFT has GREATER DENSITY than the box on the
right because is has MORE MASS IN THE SAME VOLUME
DENSITY is the ratio of an
object’s
MASS
to its
VOLUME
.
Calculating density with known mass and
volume:
determine the density of a material that has
a mass of 36g and volume of 2.5 cm
3
.
Calculating volume with known mass and
density:
find the volume of 50g of olive oil if the
density of olive oil is 0.80g/mL.

Measuring Volume
We will be using
graduated cylinders
to
find the volume of liquids
and other objects.
Read the measurement based on
the bottom of the
meniscus
or
curve. When using a real
cylinder, make sure you are eye-
level with the level of the water.
What is the volume of water in
the cylinder?
43 mL
Measuring Solid Volume
We can measure the volume of regular object
using the formula
length x width x height

Measuring Mass
We will be using
triple-beam balances
to find the mass of various objects.
The objects are placed on the scale and
then you move the weights on the beams
until you get the lines on the right-side of
the scale to match up.
Once you have balanced the scale, you add up the amounts on each
beam to find the total mass.
What would be the mass of the object measured in the picture?
300 g + 30g + 5.3g = 335.3g
Concepts of density, mass, and volume through visual representations and calculations. Understand how layers form based on mass and volume relationships. Learn to calculate density with known mass and volume and determine the volume of objects using different methods. Enhance your understanding of measurement activities and how to measure solid and liquid volumes accurately.

Measuring Solid Volume We can measure the volume of regular object using the formula length x width x height. 9 cm 9cm X 10 cm X 8cm = 720cm3 8 cm 10 cm We can measure the volume of irregular object using water displacement. Amount of H2O with object = 200mL About of H2O without object = 260mL Difference = Volume = 60mL
