Soil Salinization Lab  Soil Salinization is the process of salt becoming concentrated in areas where irrigation is used to make soil fertile.  Why? Irrigation water usually come from underground aquifers, which have a lot of minerals dissolved in them. In areas with a dry climate, the water evaporates, leaving behind salts in high levels.

Soil Salinization Lab- in your lab book 1. Pre-Lab: compare answers 1-10 with your new group. Then, make a flowchart or some other visual representation of the background info.  What causes soil salinization?  What are the negative effects?  Where does it happen? Somewhere in your visual representation, also include definitions for: irrigation, minerals, salinization, aquifers, osmotic potential, germinating seeds

Soil Salinization Lab  You will test 8 salt solutions, varying in concentration between 0-4%, using the directions at the top of page two and bottom of page Decide on your concentrations and determine how you will make them as a group. Show calculations for all 8 baggies, with units, in your lab book (can split this work up) 2. Discuss a procedure as a group and record a quick rough draft of it. 3. Do it!

Due next time…  Type up a testable question, hypothesis, procedure, and empty data table in a Google Doc.  Share it with me before class starts! 
