WHAT’S

HAPPENING?

From your experiment, you found

that leaving the gum in water

removes the ﬂavoring and sugar

from the gum, leaving only the

gum base. This is because the

universe has a natural tendency

to go from order to disorder. In

physics, the measure of the degree

of disorder within a system is

called entropy. This is why after

cleaning up your room, it gets

messy again within a few days!

So, the sugar and ﬂavor will

spread out from inside the gum

where there is a lot of ﬂavoring

(ordered) into the water where

there is no sugar or ﬂavoring

(disordered). This process is called

diffusion.

1. Removing the

flavor from the gum

You will need:

Two pieces of your gum, two glass

jars or drinking glasses, water, paper,

pen, tape

Here’s how:

Fill one glass jar or drinking glass

with hot water and one glass jar

or drinking glass with cold water.

Label the jars by writing “Hot”

and “Cold” with the pen on strips

of paper and taping them to the

jars.

Place one piece of gum in each jar.

Let the gum sit for about one day.

Remove the pieces of gum from

their respective jars. Record your

observations.

EXPERIMENTS

WITH GUM

PART

Now let’s do some

science experiments!

Now that you have made your

pieces of gum, let’s do some science

experiments with them.

Hot Cold

Safety Note: Caution! High

temperatures. There is a risk of burns.
