Why Do Mushrooms Glow? | Nature's Nightlights for Kids

How does yeast make bread rise? Discover the kitchen chemistry of yeast in this fun homeschool STEM science podcast episode for kids and families. Deep inside your kitchen pantry rests a packet filled with billions of tiny, sleeping creatures. They are not plants or animals—they are invisible fungus chefs called baker's yeast! When you treat them to a warm bath and a snack of sugar, they wake up starving. As they feast, they perform a special trick called fermentation, breathing out millions of microscopic carbon dioxide balloons . Without a trap, those gas bubbles would just float away into the air. That is where flour comes in! Flour mixes with water to build gluten , an elastic, stretchy net that catches every single bubble. When the dough goes into the hot oven, the bubbles puff up one last time in an 'oven spring' before baking solid, turning sticky dough into warm, fluffy bread.
