Transgenic food: a world to discover
As I am very interested in science, I decided to take up this project as a challenge to develop my knowledge in this area. And I am not the first one as one day, when observing the pulverisation of a culture to fight the plague, a scientist must have thought: 'What makes the culture resistant to the plague? It was not necessarily a pesticide....' This illustration functions as a pretext to introduce the study of transgenic food (G.M.O.). This concerns the effectuated modifications in the laboratory to plants of which the characteristics are subsequently altered, with the objective of strengthening, for example, the resistance to the plague, allowing for increased production, etc. In the study the positive and negative aspects of G.M.O. are analysed, with a practical component .

The distillation of red wine
The main reason we did this project was curiosity, a strong desire to understand the mechanisms of life and an interest in experiments and their results. The purpose of this experimental project is to separate ethanol from red wine through a simple distillation technique. In order to do so, we used an experimental apparatus required to carry out a simple distillation, in which we included a temperature sensor connected to a computer. Also, we used a digital densimeter to monitor the alcohol percentage (by volume) in the distillate. The data obtained were processed to make a study of the temperature evolution, distillate volume, and the alcohol percentage in the distillate and in the residue as a function of time .
