In the second unit, students learn…

This book describes one approach to building and operating biogas systems. The biogas systems include raw material preparation, digesters, separate gas storage tanks, use of the gas to run engines, and the use of the sludge as fertilizer. Chapters included are: (1) "Introduction"; (2) "Biogas Systems are Small Factories"; (3)…

This book is an outlined for the short study (1- to 2-weeks) of chronobiology, a field of science that explores the relationships between time and biological functions. It develops step-by-step the reasoning that leads to the current scientific understanding of biological rhythms. The unit can be inserted into a standard middle or high school…

Units of study to help elementary children learn about the aging process are provided. There are five units. In Unit I, "Chronological Aging," children learn that aging is a continual process, that generational cycles ensure the survival of the human species, and that species depend on each other for survival.
