Chemical weapons

On Friday 17th October the KVARTA class (students aged 14-15) had an unusual  chemistry lesson - their chemistry and physics teacher, who is also their form teacher, Alena Pecinová, had prepared a special class on chemical weapons in wars, with the focus on the First World War. I entered the classroom and planned to stay just for a few minutes as I wanted to take some photos. However, the teacher´s lecture was so interesting and catching that I couldn´t help staying all 45 minutes. Also the students, who are usually very talkative and sometimes even not very concentrated, were listening all the time with great concern, even if the narrating and photos were sometimes rather tough. Some of the photos were then used in a presentation and one of the students added subtitles to the slides so you can read it
and partly experience the wonderful lesson too.
