Sourdough starter

Math

• The child learned about ratios and proportions while measuring the ingredients for the sourdough starter.
• They practiced addition and subtraction by adjusting the quantities of flour and water based on the recipe.
• They learned about time and sequencing as they followed the process of feeding and maintaining the sourdough starter over several days.
• They practiced counting and organizing as they kept track of the days and marked their progress on a calendar.

Science

• The child learned about the process of fermentation and how the yeast in the sourdough starter helps the dough rise.
• They observed the changes in the starter over time, noting the bubbles and the sour smell that indicated fermentation was occurring.
• They learned about microorganisms and how they play a role in making sourdough bread.
• They practiced observation and documentation skills by recording their observations of the sourdough starter's progress.

Continued development can be fostered by encouraging the child to experiment with different variations of the sourdough starter recipe, such as using different types of flour or adding additional ingredients for flavor. They can also explore the science behind fermentation and the role of different microorganisms in bread-making. Additionally, the child can practice measuring and adjusting ratios by experimenting with different hydration levels in their sourdough starter.
