MY SIX STEP SCIENTIFIC EXPERIMENT!! FANTASTIC FOAMY FOUNTAIN!! What makes the Fantastic Foamy Fountain?
First Step: BY: CAROLYN PARKS Is I went to the following website; to choose my experiment:
http://www.sciencebob.com/experiments/index.php.
After researching several experiments, I decided to do the "Fantastic Foamy Fountain."
I gather all of my supplies and ingredients

Ingredients:
1/2-cup ( 20 volume/6% solution) Hydrogen Peroxide
1-TBSP (1pck) Dry Yeast
1-TBSP Dish Washing Soap
3-TBSP Warm Water
8-drops Food Coloring

Now that I have gathered all of my ingredients and supplies. I will combine all of the ingredients into 2-16/oz bottles; one with yeast and the other without yeast. Start the Experiment Second Step:
Bottle #1 Bottle #2
Pour 1/2-c hydrogen peroxide Pour 1/2-c hydrogen peroxide
into bottle into bottle
Add 8 drops of favorite food Add 8 drops of favorite food bottle coloring into bottle coloring into bottle
Add 1-TBSP of liquid dish Add 1-TBSP of liquid dish
soap into bottle and swish soap into bottle and swish
around. around.
Add 3-TBSP of water to In a separate 8 0z cup, combine 3-TBSP
bottle of water to 1-TBSP of yeast-mix for 30 sec
Now the Adventure Begins!!
Pour the yeast water into bottle #2, and watch the "Foamy Fountain" begin. Third Step:
As I watched my experiment foam in bottle #2 and not bottle #1; I immediately
noticed the difference.
With the following table I marked my data that I collected to prove my hypothesis.

Bottle #1 Bottle#2
Some bubbles formed. Bubbles starting foaming and then
the foam began and lasted for about
10 minutes.
Now that I have collected my data, I will analyze the data.

Data proves that each tiny bubble is filled with oxygen, because the yeast acts as a catalyst (helper) to
remove the oxygen from the hydrogen peroxide to create lots of bubbles. The Big Question and Hypothesis Step Four:
What Makes The Foam?
Adding all ingredients together makes the foam, and since bottle #1 did not have yeast it did not foam like bottle #2.

Step Five:
Did I prove my Hypothesis?
If I place hydrogen peroxide, water and yeast mixture, and dish soap into a bottle, it
will foam.
The answer to my Hypothesis is, yes it did foam. Observe and Analyze experiment and collect data Supplies:
2-16/oz plastic water bottles
1-8/0z plastic cup
roll of paper towels
funnel
tray
Safety Goggles-Very Important (Do not do without goggles)
