The objective of this lesson is to get students acquainted with the basic principles of sea water desalination and to make them appreciate the importance of sea water desalination in the Kingdom of Saudi Arabia due to the scarcity of fresh water natural resources. This requires a discussion of osmosis and reverse osmosis as the fundamental physical properties upon which sea water desalination works. To complete the picture, the reverse osmosis technology is investigated. This lesson does not need deep scientific knowledge by students. It is enough that the students know the difference between fresh and saline water, and are able to understand focus pressure and percentage of units and the membrane force and the quasi-force. The video time of this lesson is 27 minutes, allowing 21 minutes of classroom activities. There are two main activities need to be conducted by the students at home, individually or in groups. The procedures and the necessary materials and tools are identified in the video lesson.
