A definite idea!!!!!

Hello again!  We have come up with a definite experiment to undertake on saturday. We are going to create 3 different styles of solar stills to distill ocean water. We will then be comparing the 3 results looking at the volume collected and salinity of the distilled water.

This is the list of materials we will need:

• bowl
• plastic cup, 1" shorter than sides of bowl or cut to size
• tape or rubber band large enough to go around bowl
• small rock or weight
• salt water
  We will be using clear saran wrap to cover one test, black fabric for the second and a colored plastic shopping bag for the third.
  
  
  We are testing these specific materials as they are more readily available if you were stranded at sea than any of the other methods we researched.
  
  
  Until next time...the team
