The science, gently

  • Loggerhead sea turtles can sense the Earth's magnetic field, and they use it like an invisible map of the ocean.
  • Many females return to nest on the same stretch of coast where they hatched decades earlier.
  • A sea turtle cannot pull its head into its shell, so it relies on calm, steady swimming to stay safe.

Wonder together

  • If you had a compass inside you, where would it always point?
  • What do you think the ocean sounds like from underneath?
  • Which beach would you swim back to, no matter how far away you were?

Tonight's calm-down

Lie still and imagine floating the way a turtle swims: slow pushes, long glides. Breathe in as she pulls her flippers, breathe out as she glides. Ten glides is usually enough to feel the waves settle.

There's so much more to explore.

The episode is a whole story on its own. But if the wondering keeps going after the audio ends, the Family Guide opens this one all the way up: the same calm voice, turned into something you can do together at the table the next morning.
