During our “Food from Scratch” theme, les Inventeurs learned how yeast works. After discussing how yeast eats sugar and releases gas, we tested it by placing sugar, yeast and water in a bottle, and covering it with a balloon. This also became an opportunity to compare salt and sugar, as they both look the same, but don’t taste the same or react the same way with the yeast. We added an extra bottle with salt and yeast to compare its reaction to the sugar bottle. Our scientists tasted both salt and sugar and voted for their favorite. As it turns out, we learned that both Les Inventeurs and yeast prefer sugar! As we observed and illustrated the results of the experiment, we explain that the air in the balloon is just like the air bubbles that yeast creates into bread dough. Later in the week, we made our own loaf of bread, first observing how the yeast made the dough grow, then finding all the little air bubbles it created once the bread was baked. Science never tasted better!
