Smith, a cognitive psychologist who runs a district-wide enrichment program, describes research on the differences between the thinking of gifted and more typical students and ways to challenge and develop the cognitive processes of gifted students in grades six through eight through science units. He presents units in human memory and physiology, physics, and food science that contain overviews of content, process, and product/assessment goals; discussions of how the unit challenges and promotes intellectual gifts; links to national standards; detailed daily lessons and homework assignments; activities; adaptations to different classes and junior high grades; and handouts.
