Sourdough Bread Science

Long ago, my husband took a job as a bagel baker, which led to a career in bread baking. Sourdough was just a way of life! It took until later to understand the science behind it.

The actual maintenance of a sourdough starter is likely outside the scope of preschool science. If you are interested in learning more today, Cultures for Health has some helpful tips, videos and projects all about sourdough! We wanted to share an easy-prep science experiment that can be done with regular yeast and everyday household liquids. 

For this simple experiment, you will need:

-Yeast (not instant)
-Various liquids (see below)
-Cups or bowls
-This printable

You could try this with any liquids you like! Other than the various water temperatures, be sure to have the liquids at room temperature.

-Ice water
-Warm water
-Hot water
-Soda water
-Almond milk
-Dairy milk
-Apple juice
-Cider vinegar
-Soda w/ sugar
-Soda w/ corn syrup
-Soda (Diet)
-Water & baking soda (let sit 5 min before using)
-Water & aspirin (let sit 5 min before using)

Simply mix about 1 tsp. of yeast into 4-6 oz. (or 1/2 - 3/4 C) of liquid in a cup or bowl. Label or note each mixture. Watch mixtures as they change. Look from above and record the results on the printable! (We used dollar store plastic cups for this. But, another option would be to do these mixtures within Ziploc bags! Please be wary though as the bags could explode due to the activity of the yeast.) We were surprised at what liquids had the strongest reactions. We invite you to investigate this, too!

Meet Kristin:

Hi! I am Kristin and I blog over at smartEpartE.com. When our son, E was 2 I jokingly called him a "smarty party," hence the name of the blog! It served as inspiration to keep up with weekly tot school themes, and perhaps, share some ideas with others! Thank you for visiting over at smartEpartE.com or on Pinterest!
