While traveling through space, Hooke looked around and saw that, there in the middle of the solar system, was a planet really diferente from all the rest. It was a blue and green planet, very bright, with a moon revolving around it. It was planet Earth!

He decided to investigate what had made it so special. He got closer and discovered the wonderful things which don’t exist on other planets. He discovered that the blue of the planet was the water which covers the surfasse of the Earth, and that the green was from the plants that exist there. He also discovered that there are many varieties of living beings that inhabit the Earth. And he thought: “What makes this planet so diferente form the others? Why does life exist here?

He decided to investigate and went there. He went to a country called Portugal. He floated above it and decided to stop in a city called Coimbra. There, he saw a river. It was rio Mondego. He got closer and said:

- So much water! Where does this water go?

He jumped into the water and let himself be taken away by the current and ended up in the sea.

When he got there he decided to dive in and looked at the bottom of the sea. He was very sad because he saw sunk boats, fish swimming… and lots of rubbish at the bottom of the sea. He brought it to the sand and too kit to the recycling bin. He put the glass bottles in the recyclinh bin and plastic and metal containers in the container. He also warned everyone on the beach not to throw rubbish on the sand, because the waves come up and take it out to the sea. Then he looked out to sea and saw all the fishies saying: “ Thank you Hooke for your help!”

It was really hot… he sato n the sand and looked out over the horizon. He observed that a mist was coming out of the water that got thicker and darkened the sky. Suddenly, he saw a lightning, heard a thunder and it started to rain. Hooke got scared and ran because he didn’t want to get wet. He ran to a shelter and sat watching the landscape by the window. Everything was flooded. What now? He couldn’t get out. He waited, waited, waited… until the water dissapeared. “Where did the water go to?”, he wondered. He decided to investigate and discovered that the water infiltrates the soil, runs to the sea and then to the sea.

Hooke started thinking about what he had seen and discovered something fantastic: the water cycle! He also understood how all living beings on earth dependo n it. Without water, life wouldn’t exist on Planet Earth. He was observing this wonderful phenomenon when he realized that the shelter where he was, seemed a diferente place. He aproached a door and, inside he heard voices! He peaked through the door that was ajar and realized that it was a class. He stood there, watching attentively, and he heard that there were many countries where there isn’t any drinkable water while in other countries people waste water…

He was aprehensive and went to investigate what was happening in many parts of the planet. What he discovered made him very sad. Men were polluting Earth and, consequently, the water, contaminating it and making it undrinkable, harming all living beings. So he made up his mind: he would visit children in several schools around Europe, make diferente experiments with them, alert them to the importance of water in the life of all living beings, and consequently to the importance of saving water.

And that’s what Hooke has been doing since the school year 2017/ 2018, leaving children happy because they know they can contribute to theis cause and try wonderful things with the help of their tecahers.
