Purpose: 


The purpose of this science fair project is to explore the properties of carbon dioxide.  Carbon dioxide is a gas found in the atmosphere.  Carbon dioxide is made up of one carbon and two oxygen atoms.  Often times it is referred to by its formula "CO2".  Plants use carbon dioxide to feed themselves during photosynthesis.  In its solid state, carbon dioxide is called dry ice.


In this science fair project you will create carbon dioxide using sugar, molasses, and yeast.  You will also create carbon dioxide by fermentation of yeast and sugar.  This fermentation will create a carbon dioxide gas that has the ability to inflate a balloon.


Note:  You will need several days to complete this science fair project.


Hypothesis: 


The enzymes in yeast cause sugar to convert to alcohol and carbon dioxide gas.


Variables:


Use of yeast with sugar and/or molasses and water


Materials Needed:


  • Two Gallon jugs
  • Beach ball
  • Cork stopper
  • Medicine dropper
  • Balloon
  • Spoon
  • Measuring cup
  • Water
  • Sugar
  • Molasses
  • Yeast
