A and 9. B. The lessons in both classes were similar. Pupils were to form groups and then work with worksheets. The worksheet focused on redox reactions. During the students' independent work, I went around the class and tried to help the students and explain their shortcomings. I was intrigued by the fact that many students managed to fill in the sheets quickly and independently.
