This 4 week unit is centered on a 276 slide Power Point. The slide shows include the concepts associated with the Earth's formation and the evolution of life forms. Note slides precede each concept, and quiz slides and answer slides follow each concept. A final test key finalizes the slide show. Slides invite interaction and are loaded with eye catching and interesting pictures and effects. The slide show may be used as a primary source or with supplemental texts, depending on teacher proficiency in this subject. Hard copy masters for lab activities and in-class worksheets supplement the slideshow. Included lab is Universe/Earth time line. Class Worksheet is a Geologic Period fill in chart. Notes and a unit organizer listing student goals, 27 homework assignments, and related films are also included to complete the teaching unit. The included teacher guide for this unit’s use will be invaluable for incorporating it into your curriculum. I have used this slide show for several years. I have found it particularly helpful in differentiating needs all students, including SPED and bi-lingual. Your students will love this unit and so will you.
