Feasting Yeast

He won a medal at the school Science Fair, and almost spontaneously combusted!

One of Trenton's greatest joys in life is Science.  He loves to see experiments unfold, so when the school science fair was an option, we couldn't miss the chance to submit a project.
We worked hard to find a project that he would understand and have fun with, and we decided to use yeast.  We tried several ideas before we finalized and perfected our project.  We started by testing how yeast grows with different amounts of water.... and honestly... we failed as parents.  The pictures look fun though.  Take a look...






Once we discovered that the yeast would overflow into the balloons, and our ratios weren't working so well with the beakers we had, we had to change our hypothesis.

Trenton understands that yeast likes to eat things and that it produces gas the more it eats.  So, he wanted to see if yeast likes to Tabasco Sauce, since he likes it too.

We had 4 bottles with 104 degree water.   One was our "control" with just yeast.  One had Tabasco Sauce, one had sugar, and one had a cookie.

After 20 minutes... this is what it was looking like
 We measured, graphed, and waited some more


After it was all done, we had to make it look pretty.
 Then... the judging.  With over 100 booths, Trenton was one of the 12 children selected.  If you zoom in to this image, you can see him levitating off the ground and near explosion.  I think I got emotional seeing him so proud of his accomplishment.  

I guess the extra time spent on his booth was worth it. 
Congratulations Trenton on your big accomplishment!  I can't wait to see what you explore next!

Looks like anything but a failure as parents! Way to go. That is so awesome that you supported him so amazingly in his excitement for science.
