Eratosthenes and the Measurement of the Earth's circumference

De Medición del radio de la tierra por 3º ESO Bilingüe

Last Thursday 26th March we did an experiment with our Bilingual teachers: we tried to measure the circumference of the Earth in the same way Eratosthenes did in the century II before Christ. He discovered then that the Earth was not flat.
We studied Eratosthenes's life in the English class, in Geography we learnt all the processes he followed until he calculated the radius of the Earth. In Maths we learnt some trigonometry, specifically tangents, to be able to measure the angle of the sun's shadow length. Finally, in the technology class we spent a week building a gnomon, or stick, to be able to measure the sun's shadow length every ten minutes when the sun rays were overhead.
We took the data and sent the results to an observatory centre in Barcelona.

25th November International Day Against Violence to Women

At least one out of every three women around the world has been beaten, coerced into sex, or otherwise abused in her lifetime — with the abuser usually someone known to her. Violence against women and girls is a universal problem of pandemic proportions.
There is a campaign launched by UNIFEM (United Nations Development Fund for Women) to sign your name saying NO to violence against women.

Listen to the video and then sign your name if you consider it necessary:



Add you name to an ever-growing movement of people who speak out to put a halt to this shameful human rights violation.

Every signature counts!

International Women's Day

Next Saturday 8th March is International Women's Day. We are going to work on a Web Quest done by an English teacher called Elena González Guerrero from IES San Jose . We'll work in groups of five and we'll research on six women: Toni Morrison, Dorothy Crowfoot Hodgkin, Ada Augusta Byron, Marjorie Jackson Nelson, and Edmonia Lewis. One part of the group will research on their lives( biographers), a second part on their work (work researchers)and the third part on the cities where they spent most of their time (travel agents). After your research you will have to present your work orally. Good luck!!!!

Recipes day

Recipes day

Before Christmas we spent more than a week working on recipes in English and French. We learnt the specific vocabulary of cooking instructions and kitchen utensils. In the French class you cooked crêpes and in the English class you learnt about nutrients, the nutrition pyramid and how to eat healthy food. Our final task was to cook recipes originally written in French and English. The class was divided into eight team and each team cooked two recipes. There was a jury that voted for the most delicious dishes. The winners were Ismael Beltrán, Pablo Spearpoint and Jaime Vázquez and they had a present from the French and English Department: a pen drive for each one of them. Good luck, we hope you'll find them useful!
