The phenomenon of brine rejection: a practical proposal for prospective primary teacher training
The fact that sea ice may be a suitable source for fresh water is nothing new; in fact, sailors were aware of this long ago. Nevertheless, the issue that ice does reject the ions of a saline solution is not a well known topic by both novice learners and prospective teachers. This paper describes a p...
