Lesson One—Creating a Life Comparison Bar Graph
On the first day of teaching the unit give students graph paper. Explain to the students that they are to begin to construct a bar graph that will be used throughout the unit. Along the left side students are to number the lines using divisions of twenty. Starting from the year 640 B.C. at the bottom and working up until the year 300 B.C. Along the bottom students should skip every other column. (Note the paper should now be turned so the names can be written inside the column rather than across.) The following names should be copied in this order: Thales, Anaximander, Anaximenes, Empedocles, Hippocrates, Democritus, Plato, and Aristotle. As each scientist is introduced students should be given their life span dates and the graph can be filled in. This on going activity will be useful in helping the students to visualize the time relationships between these men and their ideas.
