Outlining is an important skill to develop. The goal is to pick out the information that is most important and leave behind the fluff so that your final result is a condensed version of the original. The process of outlining is an important skill and the resulting outline is a good tool and study guide. When we have quizzes, they will often be open note so if you have a good outline the quizzes should be a breeze.

Directions: Outline chapter 1, section 1 (pages 5-8). First read the objectives and key terms (page 5). At a minimum, these should be explained in your outline. The outline should be a brief summary of the chapter. Read one paragraph at a time and then sum it up it a phrase or two. It is not necessary for the outline to be in complete sentences. A finished outline will probably be 1-2 pages if hand written or less than 1 page if typed.

After you finish your outline, re-read the objectives to see if your outline meets those objectives. Then read the section review and see if you can answer those questions in your head. You do not have to answer the on paper but you should be prepared to answer them if you see them on a quiz or a test.

An example of an outline of the first paragraph might be as follows:

Environment – everything around us, natural or man made, living and non-living, more than what we can see, made of complex relationship with all around us.

The outline of the second paragraph should contain a definition of environmental science but does not have to contain the details about Keen High School’s mussel research.
