Four cards fill in one at a time: a bat finds a moth with echoes, a bee sees an ultraviolet pattern on a flower that looks plain to us, a pit viper senses a warm mouse in the dark, and a migrating bird senses Earth's magnetism. The video ends with the idea that some animals have senses beyond ours.

Transcript

What the lesson says

Can some animals sense things that we cannot?

Many bats find food in the dark using echolocation.

The bat sends out very high squeaks.

The squeaks bounce off a moth and come back as echoes.

The echoes tell the bat where the moth is.

Bees can see ultraviolet light, but our eyes cannot.

Many flowers have ultraviolet patterns that lead bees to the nectar.

A pit viper has a small pit on each side of its face.

The pits sense the heat of a warm mouse, even in the dark.

Many migrating birds can sense Earth's magnetism.

Like a compass, it helps them find their way.

So, some animals have senses beyond ours.
