European Quality Label

Well, further recognition for (y)our work and another award for your class. Pleased?
As I always say,
1. If you're going to do something, do it well, the best you can!
2. Those who work hard will, sooner or later, be recognised and rewarded for it.
We started at a national level and now we've reached out the European Quality Label :) End of the line???

Riddle

What Am I?

I have no colour,
not even white.
but sometimes I'm wide and blue.
Sometimes I'm still,
and sometimes I rush,
and I can fall down on you.

I can change my shape,
I often do,
but I'm hard to hold in your hand.
You need me to make
your castle stand up
when you're playing in the sand.

I haven't much taste
but on a hot day
your tongue's hanging out for me. 
Then I'm cold,
but I can be hot
When I'm in your mum's cup of tea.

WHAT AM I?

1. Here's a different activity: the first of you to guess and explain the riddle correctly will be awarded a prize, but all others who participate today will get something - that's a promise!

2. Another Challenge: for every single book you read during this Easter break and prepare a presentation to share here, in our class blog, you will be awarded another book in return, in English, and suitable to your level of English.

Is there anything else I can do to motivate you to read and engage in our class blog and activities??? Please, do let me know. LOL.
