Wild Sourdough

In this activity, learners explore chemistry and the microbial world by making their own sourdough starter and bread at home using only flour and water. Learners also have the option to take part in a citizen science experiment by collecting and sharing data from the 10-day sourdough starter making process with the Rob Dunn Lab at NC State University. There are still many mysteries about the microbial world, and the Rob Dunn lab is interested in participants findings from creating sourdough, or sibling sourdoughs at home. Activity includes instructions, a video introduction, a sourdough recipe, background information on the nature of the experiment, and an explanation of how making sourdough at home can help the scientific community.
