A young boy standing in a sunlit field and looking up at a wide bright blue sky with soft clouds.

Big question

为什么天空是蓝色的？

Wèishénme tiānkōng shì lánsè de?

Why is the sky blue?

天空看起来是蓝色的，因为阳光在空气里散开的时候，蓝色的光最容易被我们看见。

Tiānkōng kàn qǐlái shì lánsè de, yīnwèi yángguāng zài kōngqì lǐ sànkāi de shíhou, lánsè de guāng zuì róngyì bèi wǒmen kànjiàn.

阳光里面有很多颜色。蓝色的光最喜欢在高高的天空里跳来跳去，所以我们的眼睛会看到蓝蓝的天空。

Yángguāng lǐmiàn yǒu hěn duō yánsè. Lánsè de guāng zuì xǐhuan zài gāogāo de tiānkōng lǐ tiàolái tiàoqù, suǒyǐ wǒmen de yǎnjing huì kàndào lánlán de tiānkōng.

你能找到别的蓝色东西吗？

Nǐ néng zhǎodào bié de lánsè dōngxi ma?

The sky looks blue because sunlight spreads through the air in a special way.

Sunlight has many colors in it. Blue light likes to bounce around up above us, so our eyes see a big blue sky.

Can you point to something else that is blue?
