PRE-LAB WRITE-UP 

 LabBench quizzes turned in before we conduct the lab.  These can be accessed at the following URL: http://www.phschool.com/science/biology_place/labbench/  

After reading the Lab Handout instructions and completing the LabBench Tutorial and Quiz, answer the following questions for each section of the lab.  LABEL EACH SECTION CLEARLY (e.g. A, B, C or D and 1, 2, or 3) and LEAVE A SPACE BETWEEN EACH SECTION  (e.g. A, B, C, or D) of the lab. This write-up should be COMPLETED on your desk from the moment the bell rings on the day before the lab.

1.	What is the purpose of this section?  (What is being studied?) 
2.	What is your hypothesis concerning this section?  (How will one variable change as a result of the other?)  Note: Identify the independent and dependent variables here by writing and circling “(IV)” and “(DV)” where appropriate. 
3.	Explain, in detail, the scientific reasoning behind your hypothesis (hypotheses).
