Sourdough starter

Math

• The child learned about ratios and proportions through the process of measuring and mixing the ingredients for the sourdough starter.
• They practiced counting and using numbers when following the recipe instructions.
• They gained an understanding of fractions when dividing the dough into portions for baking.
• They reinforced their understanding of time and elapsed time by observing and tracking the growth of the sourdough starter over several days.

Science

• The child learned about the biological process of fermentation and how yeast and bacteria interact to create bubbles in the sourdough starter.
• They gained knowledge about microorganisms and their role in food production.
• They learned about the importance of maintaining the right conditions (temperature, moisture, etc.) for the sourdough starter to thrive.
• They observed and documented changes in the sourdough starter over time, developing their skills in making scientific observations and drawing conclusions.

Continued development can be encouraged by allowing the child to experiment with different types of flour or different ratios of ingredients to see how it affects the sourdough starter. They can also explore using different techniques for shaping and baking the sourdough bread. Encouraging them to research and learn about other types of fermented foods can broaden their understanding of the science behind food preparation.
