Three Layer
Density
Experiment
Materials needed:
• Oil• Cork• Coin• Water• Grape• Honey• Tall Clear Cup
First, fill a
third of the
cup with
honey.
Next, fill a
third of the
cup with
oil.
After that, fill a
third of the
cup with
the colored
water.
Wait for all three
liquids to settle.
Before we continue,
what do you think a
liquid is?
A liquid can move
like water.
A liquid take the
shape of its
container.
Make a prediction
with the coin.
Would the coin float
between the oil and the
colored water, or sink in
the honey.
Each of the three
liquids
have different densities,
making three
separate layers.
I predict the coin
will float on top of
the water because
the coin is
________________.
I predict the coin
will float between
the oil and water
because the coin
is________________.
I predict the coin
will float between
the oil and honey
because the coin
is________________.
I predict the coin
will sink in the honey
because the coin
is________________.
Drop the coin in the cup.
Draw and write your
results.

What were to
happen if you drop
a different coin?
Make a prediction
with the grape.
Would the grape float
between the oil and the
colored water, or sink in
the honey.
I predict the grape
will float on top of
the water because
the grape is
________________.
I predict the grape
will float between
the oil and water
because the grape
is________________.
I predict the grape
will float between
the oil and honey
because the grape
is________________.
I predict the grape
will sink in the honey
because the grape
is________________.
Drop the grape in the
cup.
Draw and write your
results.

The grape is not as
Make a prediction
with the cork.
Would the cork float
between the oil and the
colored water, or sink in
the honey.
I predict the cork
will float on top of
the water because
the cork is
________________.
I predict the cork
will float between
the oil and water
because the cork
is________________.
I predict the cork
will float between
the oil and honey
because the cork
is________________.
I predict the cork
will sink in the honey
because the cork
is________________.
Drop the cork in the cup.
Draw and write your
results.

All three items
(grape, coin, and
cork) have different
densities.
The most dense
goes to the
bottom and the
least dense goes on
top.
Comparing all three
liquids, which liquid
was the most
dense? Why?
Honey was the most
dense.
Water was more
dense than oil but
was less dense than
honey.
Oil was the least
densest.
Comparing all three
objects, which object
was the most
dense? Why?
The coin was the
most dense.
The grape was more
dense than cork but
was less dense than
the coin.
The cork was the
least densest.
