Earwax: Gross or Genius? | Earwax, Hearing & Human Body

How do animals survive freezing in winter? Discover how wood frogs and icefish use natural antifreeze in this fun educational homeschool STEM science story. Deep beneath winter leaf piles and inside polar ocean waves, secret ice chemists are brewing their own survival potions. While freezing temperatures would normally turn living cells into shredded ice, animals like the incredible wood frog and Antarctic icefish produce natural antifreeze. Wood frogs pump sweet glucose through their organs, allowing up to 70 percent of their body water to freeze into solid ice while keeping their delicate inner cells safe. When spring arrives, these miraculous frogs thaw out from the inside out, kickstarting their frozen hearts and hopping away as if waking from a simple nap. From see-through icefish swimming in polar waters to winter snow flies dancing on snowdrifts, nature has unlocked amazing recipes to conquer the deepest freeze. Ask in the car afterwards: How does the wood frog use sugary glucose like natural antifreeze to protect its cells? If you had to survive a freezing winter, would you rather freeze solid like a frog or make your own heat like a snow fly?
