Sixth-graders participated in a science experiment exploring how the presence of sugar or salt affected yeast activity.  Six water bottles and six balloons contained different measurements of these substances.  Balloons captured the carbon dioxide that escaped from the yeast.  The circumference of each balloon was measured every ten minutes and recorded on a graph.  The results?  Yeast loves sugar, just like us!!
