Most of the light we see comes from the sun. The sun is like a big, bright ball of fire in the sky that lights up the day.

We need sunlight because it helps us see everything during the day and keeps us warm. Plants also need sunlight to grow and make the food we eat.

Question 6

What happens when light hits the Earth?

Accepted Answer

When sunlight reaches Earth, it lights up everything we see and helps warm up the ground, water, and air. That's why it feels warm when you're outside on a sunny day!

Question 7

Why do we have daytime and nighttime?

Accepted Answer

We have daytime when our part of the Earth faces the sun, making it bright and sunny. We have nighttime when our part of the Earth turns away from the sun, making it dark.

Question 8

Why is the sun so bright?

Accepted Answer

The sun is super bright because it's really big and hot, with lots of energy. It shines a lot of light in all directions, lighting up space and the planets nearby, like Earth.

Question 9

Can we look directly at the sun?

Accepted Answer

No, we shouldn't look directly at the sun because it's too bright and can hurt our eyes. It's better to look at the sunlight all around us, which is safer for our eyes.

Question 10

Why does the sun look yellow?

Accepted Answer

The sun looks yellow to us because of the way its light travels through the air. The Earth's atmosphere changes the sun's light a little bit, which makes it look yellow instead of pure white.

Question 11

What are shadows?

Accepted Answer

Shadows are dark shapes made when something blocks the sunlight. If you stand in the sunlight, your body makes a shadow because it stops the light from shining through you.

Question 12

Why do shadows change size during the day?

Accepted Answer

Shadows change size because the sun moves across the sky. In the morning and evening, the sun is lower, making long shadows, but when it's overhead at noon, shadows are shorter.

Question 13

Can light bounce off things?

Yes, light can bounce, or reflect, off shiny objects like mirrors or water. This is why you can see your face in a mirror or sunlight sparkling on a lake.

Sunlight has all the colors of the rainbow mixed together. When it passes through something like a prism, it splits up into different colors like red, orange, yellow, green, blue, and purple.

Question 15

How does sunlight help plants?

Sunlight helps plants make their own food through a process called photosynthesis. Without sunlight, plants wouldn't grow strong and tall, and many animals wouldn't have enough food.

What is a rainbow?

Accepted Answer

A rainbow is a colorful arc in the sky that happens when sunlight passes through raindrops and splits into different colors. It usually appears after a rainstorm when the sun comes out.

Question 17

Why is the sky blue?

Accepted Answer

The sky looks blue because the air scatters the sunlight, and blue light gets scattered the most. That's why we see a blue sky most of the time during the day.
