I love to make homemade bread. I wanted my kids to understand how yeast works to make the bread rise, so we did a little experiment with it. You know the one with baking soda & vinegar that blows up a balloon, right? Well, this is like that, but you use yeast instead. It isn’t quite as exciting & dramatic because it blows the balloon up slowly as the yeast proofs, but it was a great visual for my kids to see how it works and why.
Do do this, just use a water bottle and put in warm water- about 1/2 c., 1 Tbsp of yeast, and 1 Tbsp of sugar. Shake it gently so it mixes together. Place a balloon over the top of the bottle and watch what happens!
Make some bread dough at the same time. Help your kids see how the the yeast works to make the bread dough rise. Plus, you get some delicious bread to eat at the end. Here is my family’s favorite bread recipe!
