Transferable/Scientific Skills Developed
Transferable skills: - teamwork, - listening, - communication, - time management, - dependability, - technology. Scientific skills: - know and respect the lab safety rules; - reading and carry out an experimental procedure for chemical synthesis; - prepare a lab notebook where students should take notes of anything they do during an experiment and briefly describe the results. - representing data using symbols, diagrams, graphs and tables; - writing a lab report.

• General aims Get students excited about chemistry and polymer science. Acquire manual skills. Make sure that the students reach the scientific skills listed above. • Linguistic aims Learn new terms related to: chemicals, laboratory equipment and experimental methods. Reading and comprehension of the experimental procedure. Take notes in the lab notebook. Writing laboratory reports. Ability to speak in English with other experimenters. • Subject specific aims Learn about the physical state of the chemicals used. Learn how to handle chemicals. Have concrete evidence of what has been studied in theory. Realize the volumes of the chemicals used. Understand that a chemical reaction occurs if well defined reagent quantities are mixed. Understand that the physical state of the synthetic product may be different from that of the reagents. Develop the observation skills of young experimenters. • Target group age 17-19 • Level of competence in English (CEFR) B1 • Time required to use the resource with the students 1 hour • How to use it After a brief introduction in which the teacher explains the reaction scheme, showing the chemical formulas of the reagents and the product, the class goes to the laboratory. Here, students are organized in small work groups who are assigned a desk already equipped with all the necessary glassware, tools and reagents. The teacher and the students brainstorm on the safety rules in the laboratory and only after the teacher has ascertained that each experimenter is equipped with a lab coat, gloves and laboratory notebook, does he distribute copies of the experimental procedure. From this moment, each group can start working under the supervision of the teacher. During the experiment, each team will take notes in the laboratory notebook. This will serve them to prepare their own laboratory report in the next lesson, according to the indications that the teacher will provide. • Possible difficulties for the students Students who have partial knowledge of the theoretical prerequisites of organic chemistry (functional groups and nucleophilic addition reaction) and on polymers, may have difficulty understanding the experimental procedure.
