Why Do Boogers Form? | Mucus, Germs & Nose Biology

How do animals survive freezing? Learn how wood frogs, icefish, and snow flies use natural antifreeze to survive winter in this homeschool STEM lesson. Deep beneath frozen forest leaves, a tiny wood frog turns completely solid. Its heart stops beating, its breathing halts, and up to seventy percent of its body water turns into solid ice. Yet inside its cells, secret ice chemists are hard at work releasing a sugary syrup made of glucose that keeps vital organs safe from sharp ice crystals. From Antarctic icefish swimming with see-through blood to wingless snow flies bustling across winter drifts, animals have evolved extraordinary natural antifreeze tricks. When spring sunshine warms the ground, the frozen frog simply defrosts from the inside out and hops away into the woods. Ask in the car afterwards: How does a wood frog use sugar syrup to keep its cells safe while the rest of its body turns to ice? If you had to survive a freezing winter, would you choose the frog's freeze-and-sleep trick or the snow fly's self-heating superpower?
