This is a handout with 9 vocabulary terms and 3 boxes for students to fill in on each word under the following headings: book definition, my description, and graphic representation. Having students draw (graphically represent) their understanding of a term is a proven vocabulary comprehension technique, supported by research. It also helps the teacher to catch student misunderstandings and insure that the term is truely understood by the student.
Note: I also have a Natural Selection Power Point that can be purchased and used with this handout. It has each vocabulary term from this handout defined and additional slides for the teacher to use when explaining concepts to students.
