The PSC-4012-2 – Ionic Phenomena: A study of an Environmental Problem course focuses the principal concepts and phenomena of chemistry that are essential to an understanding of such problems as acid rain and the pollution of water by fertilizers and pesticides. It presents the atomic model and the periodic table of elements. It introduces the subject of chemical bonding, which occurs in the formation of compounds such as acids, bases and salts. On the social level, it teaches the learner to analyze the main factors contributing to acidification and the pollution of waterways. Following the presentation of a step-by-step case study, the learner is asked to assess articles dealing with problems related to the use of chemical products.
Duration: 50 hours (2 units)
This learning guide aims to help the learner achieve the following objectives:
