Do all liquids mix together?
Let’s experiment.
1 2 Add
food coloring.
Pour water
into a cup.
3 4 Pour salad oil
into an empty
jar or plastic cup.

Make it about
half full.
Add the
colored water
to the oil.

MIX.
Wait! What happens to the oil
and water?
They
SEPARATE.

Some liquids MIX together.

Others do not.

It has to do with CHARGE.
More about that later.

the for answer.
WHY
Oil and Watar
DO NOT MIX
Click on the red
question mark
the for answer.

The oil is on TOP.

The water is on the BOTTOM.

If you added honey,
it would form a third layer
BELOW the water. Try it.
Which is ON TOP?
The oil or the water?
Click on the red
question mark
the for answer.
Oil is less DENSE
than WATER.
So oil floats on top of the water.
WHY
What is
DENSITY?
Everytime
you take
a bath,
you
experience
DENSITY!
You know that
in a bathtub,
somethings FLOAT

Others SINK.
Many bath toys FLOAT. They are less dense than water. Bars of soap SINK more dense than water. They are Soap sinks In one palm
hold an object that
will FLOAT.
In the other palm,
hold an object
about the same size
that will SINK.
The bar of soap will be heavier.
Which one FEELS
heavier?
Styrofoam will float.
The clay brick will sink.
Compare two bricks
that are exactly the same size.
exactly Styrofoam Which will float
and which will sink?
Clay brick
Density of water is 1.0 gm/cm 3 The density of water is 1.0 gm/cm 2. IF the density of an object is LESS than ONE
the object will FLOAT or SINK in water?
1. IF the density of an object is GREATER than ONE,
the object will FLOAT or SINK in water?
Sink FLOAT
From the chart ABOVE:
The density of styrofoam is .15 kg/l
The density of brick is 2.00 kg/l
Step 3 Step 2 Step 1 Step 5 Select INTRO Select

DENSITY Remember - volume IS the space an object takes up. Mass, Volume and Density Song Does an object
with greater density
than water float
or sink in water?
What is the density
of water?
What is density? A brick has 2 times the density of water. Will it float of sink in water 1 2 3 4 5 Does an object with less density than water float or sink in water SINK SINK 1 g/cm³ D = mass / volume FLOAT
