Tides: How the Moon Moves the Sea

Twice a day, the ocean breathes in and out, pulled by a moon it has never touched. This episode stands at the water's edge and watches the slow pull.

The science, gently

  • The moon's gravity gently stretches the ocean, making the bulges of water we call tides.
  • Most shores see about two high tides and two low tides each day.
  • Tide pools are little worlds that practice patience between visits from the sea.

Wonder together

  • What would you keep in your tide pool?
  • Where does the water go at low tide?
  • What else in your life comes and goes as reliably as tides?

Tonight's calm-down

Breathe with the ocean's rhythm: high tide as you fill, low tide as you empty. The moon will keep the big water moving all night so that you do not have to move at all.
Go further together

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.

  • Questions written for your child's age, not just their reading level
