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.

What happened?

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.

What happened?

Draw and write your

results.

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.

What happened?

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.
