1. First, pour an amount of syrup.
2. Second, pour the milk.
3. Then pour the dish soap.
4. Then add 2-3 drops of food colouring to the
water. Then take a spoon and scoop up a little
bit of violet water , take a funnel and slowly
pour it against the side of the glass.
5. Next thing we’re going to add is the cooking
oil. Again, slowly pour it into the glass.
6. For our last layer add 2-3 drops of food
colouring to the rubbing alcohol and stir.
Again, take a funnel and put against the side
of your glass and pour it into the glass
If each ball has the same mass, which box would
weigh more? Why?
The box that has more balls has more mass. This
property of mater is called density. The density of
a material helps to distinguish it from other
materials. Since mass is usually expressed in
grams and volume in cubic centimeter, density is
expressed in grams/ cubic centimeter.
How the Density tower works?
You made your column by pouring the heaviest
liquid into the glass first, followed by the next-
heaviest liquid, etc. The heaviest liquid has the
most mass per unit volume or the highest
density. Some of the liquids don't mix because
they repel each other (oil and water). Other
liquids resist mixing because they are thick or
viscous. Eventually some of the liquids of your
column will mix together.
The same amount of two different liquids will
have different weights because they have
different masses. The liquids that weigh more
(have a higher density) will sink below the liquids
that weigh less (have a lower density).
Density is basically how much "stuff" is smashed
into a particular area... or a comparison between
an object's mass and volume. Remember the all-
important equation: Density = Mass divided by
Volume. Based on this equation, if the weight (or
mass) of something increases but the volume
stays the same, the density has to go up.
Likewise, if the mass decreases but the volume
stays the same, the density has to go down.
Lighter liquids are less dense than heavy liquids
and so float on top of the more dense layers.
