Write a purpose statement and outline of the procedures for this lab on and attach it to the back of this handout. you should not copy verbatim the procedures but rather paraphrase them in your own words and include all specific types of equipment and their parameters (i. e. 100 ml graduated cylinder) in addition to all mathematical equations to be used. a purpose statement clearly and concisely describes the goal of the experiment including the general method that will be used to meet this goal. don't resort to stock phrases; be somewhat creative. do not use the words "i, we, you, the students". do not write a pedagogical purpose. the pedagogical purpose of an exercise is not the same as the statement of purpose so statements like "we will learn" should not be included. for example, the pedagogical purpose of a lab investigating the properties of oxygen is to learn about chemical reactions and physical and chemical properties. but your statement of purpose might read "chemical properties of oxygen will be determined by carrying out reactions with sulfur, phosphorus, magnesium, and iron." you should be able to use your outlined procedure to complete the lab without using this handout. attach the purpose and outline of the procedures to this lab and bring to class on the day of lab.
