50 Years of Science & 50 Scientists is an e-zine (a magazine available only in electronic form, for example on the internet) published by the students of year 5 of Primary Education at Saint Domingo de Guzmán School in Palencia (Spain). Our student´s book is about an e-zine and the characters, in each unit, have to investigate about different topics and they have to write an article. The students have chosen this tittle for our e-zine because this year we are celebrating the 50th birthday of our school and there are 50 children of them (in two classrooms) who have felt as really scientists investigating about different themes. As the final project of this course the students have done the same, firstly, in groups they had to choose the topic they were going to work about, this topic had to be related to an article in our book but it had to be different, for example there was an article about materials, one group chose to work about silver; another article is about London and another group has worked about Las Vegas, another city,…. Then, they had to look for information at home about the chosen theme, bring the information to school and, in groups, put it in common and write an article (Cooperative learning). Finally the articles had been published. We hope you like it and you enjoy reading our e-zine.

AIR POLLUTION Poor air quality due to smoke and noxious gases can have devastating effects on the bird population in dense areas.

Air pollution can be harmful to all animals, for example, the butterflies, seagulls, pelicans or even eagles.

Air pollution can affect the daily life of these animals because the polluting particles can adhere to their feathers and their lungs.

The more toxic spills we throw into nature, the worse life animals will have, that is the reason, we, the children, ask adults to stop. Because we are killing our world using vehicles, factories,… not recycling. Using plastic and throwing them to the sea We love animals, and we want to take care of them and protect them, so we will take care of our world.
