Sourdough starter

Science

• The 4-year-old student has learned about the concept of fermentation by observing the bubbles and growth of the sourdough starter, understanding how the microorganisms produce gas to make the dough rise.
• Through this activity, the student has gained an understanding of ecosystems and the role of microorganisms in the environment and food production, as they see how the yeasts and bacteria work together to create the sourdough culture.
• The student has developed an understanding of cause and effect by seeing how feeding the sourdough starter with flour and water results in bubbles and growth, witnessing the cause-and-effect relationship of adding food for the microorganisms.

Encourage the continued development of science concepts related to the sourdough starter by discussing the science behind fermentation and the role of microorganisms in baking. You could also explore related topics such as the history of sourdough bread and the different types of bread that can be made using a sourdough starter. Additionally, you can engage the child in simple experiments related to fermentation and microorganisms using other food items like yogurt or pickles.
