Abstrakt
A project day focused on the environmental topic Plastics and their consequences with environment was organized with a group of 14-15 years olds students. They were drawn into the problem using video presentation, work with text, the lecture with expert, chemistry experimental part and workshop.
The project activities were monitored by three mind maps in the form of pre-, post and a retention test. The data show positive results concerned knowledge of participants.
It means that number of relevant terms in mind maps was rapidly increasing. Also, the possibility of overgrowth of "teacher's" project to "students'" project oriented to creation of their own artefacts was confirmed.
