Water Purification within an ecosystem

Today we introduced new vocabulary while discussing and viewing a short film that deals with water purification.  Words like evaporation, condensation, precipitation, filtration, purification and desalination are processes, some man made or natural that are shown in the film above.  It is not only important to know the meaning of these words, but we must know how to use them correctly when speaking or writing in English.

G10-02 and G10-08, your assignment for Thursday is to write a paragraph describing the natural processes that are taking place in the film above, using the vocabulary we went over in class.  Do you remember disperse and spontaneous from the flash mob article we read in The National newspaper?  How can you use those words to describe the video?  The paragraph you write must have a minimum of 120 words and be turned in at the end of the 2nd period for G10-02 and 4th period for G10-08.  Any questions you have we will go over in class.
