Transcript of The Effect Of The Amount Of Yeast On Foam Production

Foam Production
Question :
Hypothesis
I Think The Yeast Change Will Effect The Amount Of Foam Produced Because The Yeast Helps Remove The Oxygen And Creates The Foam. The More Yeast There Is The More Foam, The Less Yeast The Less Foam.
The Effect Of The Amount Of Yeast On Foam Production
By: Amari Miller
Does The Amount Of Yeast Change The Amount Of Foam Produced ?
Dependent Variable :
Foam Production
Constant Variables
Bottle
Measurements Of Peroxide, And Dish Washing Soap
Small Cup
Goggles
Food Coloring
Goggles
Independent Variable

Amount Of Yeast
Procedures
1. Pour Hydrogen Peroxide Into The Bottle.
2. Add 8 Drops Of Food Coloring For Color.
3. In The Small Cup, Mix warm Water And Yeast Together
4. Pour The Mix Into The Bottle And Let The Foam Grow.
Materials:
16 Ounce Bottle
1/2 Cup Of 20-Volume Hydrogen Peroxide
1 Tablespoon Of Dry Yeast
3 Tablespoons Of Water
Dish Washing Soap
Small Cup
Food Coloring
Goggles
Data:
Dry Yeast
1 Tablespoons : Foam Flowed For 14 Seconds
2 Tablespoons: Foam Flowed For About 23 Seconds
3 Tablespoons : Foam Flowed For About 36 Seconds

Results:
My Data Shows That The More Yeast Used, The More Foam Was Produced. It Seems Like Every Teaspoon Of Dry Yeast Added, The Longer The Foam Flowed.
Experimental Group
The Bottle With The Most Yeast, Which Was Was 3 Tablespoons.
Control Group
The Bottle With The Least Amount Of Yeast, Which Was 1 Tablespoon.
Conclusion
After Completing My Experiment, I Was Correct In My Hypothesis. The More Yeast There Is The More Foam Is Produced. The Yeast Helps Remove The Oxygen, Which Creates The Foam. So The Less Oxygen Removed, The Less Foam Produced.
