Desalinization Device Construction Project     Name
                                                    -----------------------

1)  Construct a solar-powered desalinization device capable of producing as 
    much water as possible for the least possible "footprint" area, that 
    is, the amount of surface area the device covers.  Some materials you 
    may be able to use will be provided, such as sheet plastic and tubing.  
    You may use any other materials at your disposal to construct your 
    device (popsicle sticks, tape, staples, glue, paper clips, etc.)

2a) Describe your desalinization device, its construction and how it works:

2b) If this is not the first desalinization device which you have 
    submitted, describe what is different about your new design:

9)  Multiply the efficiency of your design (from question #6a) by the 
    average amount of water collected (from question #8a) and record your 
    answer here (this is the effectiveness of your platform for the 
    conditions under which it was tested):
