In April, we had a field trip to the vicinity of our school to observe species of plants there. The students were to recognize the species. The next stage was create their own descriptions of the taken samples to examine them using a microscope and to take photos of them After the research, a group of students completed the whole material of the chosen plants, and which was exhibited and placed on the Internet. The students made QR codes and placed them on the premise of the school so that other students who are interested in the results of the group project might find out much more due to the QR codes installed in their smartphones.
