Tuesday: Eyes need light

Rocket turns off every light in the closet.

"Where did my blocks go?" he asks.

Raven asks, "What do you notice in the dark?"

Nova hints, "What is missing here?"

No light, no sight

Your eyes need light to see.

Light goes into your eye through the pupil.

The back of your eye turns light into messages.

A nerve carries the messages to your brain.

In a dark place, little light gets in.

In total darkness, you cannot see things.

Light makes things show

Rocket turns on a flashlight.

Now the light shines on his blocks.

Light shines on things in the dark.

Then you can see them.

The blocks were there the whole time!
