Abstract :Six European schools from very different parts of Europe insert ignore into journalissuearticles values(Agrupamento de Escolas da Maia - Portugal, Anne-Frank-Schule Bargteheide – Germany, Özel Bilkent Lisesi – Turkey,  Sandsli VGS – Norway, Institut Pau Vila – Spain and Liceul Teoretic Iancu C. Vissarion - Romenia, have developed an Erasmus+ project for Exchange of Good Practices, MISO, in order to increase student interest in science, foster the use of ICT with different applications for experiments, share experiences between teachers and students and collaboratively examined new approaches to teaching and learning of science insert ignore into journalissuearticles values(E-learning Tools);. In recent years the automobile industry has been looking for alternatives to reduce the consumption of fossil fuels. One of the solutions can be vehicles containing a normal internal combustion engine that uses the biodiesel as combustion This research study used Project Based Learning as pedagogical methodology, through the use of mobile devices and was done by students of Chemistry of 12th grade. Students aimed to synthesize Biodiesel by transesterification of refined soybean oil with methanol by basic catalysis using laboratory materials. They studied the effect of the amount of catalyst on the synthesis of biodiesel, they evaluated the acidity index of biodiesel and they also studied the miscibility of the produts obtained with ethanol and hexane. FT-IR was used to monitor the reaction . Mobile devices were used during the project to take photos and to record videos of the experimental procedure. Different type of APPS insert ignore into journalissuearticles values(Magisto, Animoto, Popplet and Scapple); were used to report the results . This work showed that transesterification is a simple, easy and economically accessible method of synthesizing biodiesel. This project enabled students to deepen and apply their previous and new learning, develop their critical thinking, their creativity and communication, increase their autonomy, organizational management of work, interpersonal relations and motivation for the learning .
