This is a blog created by Ms Luminati (science teacher), Ms Mathis (English teacher) and Ms Burguière (science teacher) for the students of lycée expérimental André Malraux (Biarritz, France) who are learning science in English. They want to show that science is fun, interesting and easy particularly when it is done in English!
This year we hope to work again with some fine European partners.
Let us all have fun together!
Hi!My name is Klio-Claire Fragkedaki and I'm student of Dominikos Theotokopoulos secondary school from Greece.As regards the experiment, due to the chemical reaction of the indicator(blue) of methylene,solution's colour is changing.Methylene is at first colourless because of the fact that there is no refuction conditions,but when we shake the solutuion it is oxidised.More specifically,the solutuion's loss of colour is caused by glucose and NaOH.When we shake the bottle,we manage to dissolve oxygen which oxidises methylene and solution becomes blue.
Thank you very much for your answer.. If you change "refuction" into "reduction", your answer is correct. We are happy to hear from you. Do you have any riddle for us now? Lea
