Science is Such a Gas!

This year we are exploring Chemistry with God's Design for Chemistry. Our first experiment dealt with gas, so fitting for a 10-year-old. We placed yeast and hot water in 3 bottles. Bottle 1, on the left, was our control, bottle 2 we added white sugar, bottle 3 we added molasses. We needed to see how much gas each bottle produced over the period of one hour.

This is the beginning (zero hour) for our experiment.
At approximately 6 minutes the balloon with the sugar started to inflate.
At about 15 minutes both balloons were inflated.
At 30 minutes you can see molasses has more gas than sugar. The sugar was at 6.25" around and the molasses was at 9.5".
At the end of the hour the sugar was still at 6.25" and the molasses was at 13".
Professor Z had hypothesized that the molasses would produce more gas, his theory was correct.

When asked why someone would choose to use a sweetener that does not produce the most gas he simply replied, "So there would be no exploding bread." Makes sense to me. :)

Science is going to be fun this year!
