"What am I?" haiku

These haiku are riddles, they were written by E1A students. Can you guess what they describe?

You use me to write

I have different colours

Should I get dry now?

(by Ángeles A.)

I fly near the sea

Looking at the world below

The children love me

I am a good team

My enemy is Barça

Of which team I am?

In mountains I live

I throw snowflakes to the ground

Children go to ski

(by Silvia G.)

I soon will be here

You won´t see me but feel me

Loved by everyone

I go before sleep

I will appear in the morning

I´m one in the sky 

Someone can break me

Not with a pair of scissors

It can be with words

(by Inés A.)

Solutions: a pen, a bird, Real Madrid, winter, summer, the sun, self-esteem.

And finally a very metaphysical haiku by Ángela A.:

We are born to live

We grow up to experience

Why does death exist?
