Why Does My Earwax Smell? | Body Science for Families

How does yeast make bread rise? Discover the kitchen chemistry behind fluffy bread, sleepy fungus chefs, and bubbly STEM science for curious kids and homeschool families. Inside every slice of warm, fluffy bread lies a delicious secret: a microscopic army of invisible fungus chefs hard at work! In a dry paper packet, billions of tiny single-celled yeast cells are fast asleep. But give them a splash of warm bathwater and a spoonful of sweet sugar, and they wake up hungry, starting a busy kitchen transformation called fermentation . As these tiny bakers munch away, they burp out millions of invisible carbon dioxide bubbles . Wheat flour provides a stretchy trampoline net made of gluten that catches every single bubble. When dough goes into a scorching hot oven, those trapped air pockets puff up one final time before turning golden and crisp, proving that everyday cooking is pure scientific magic!
