Testing the pH of various liquids is one of the most popular activities in 5th- through 8th-grade classrooms. The author presents an extensive pH-testing lesson based on a 5E (engagement, exploration, explanation, extension, and evaluation) teaching model. The activity provides students with the opportunity to learn about pH and how it relates to…

Describes a card game that teachers metabolism to high school biology students. (LS)

Presents a series of calculations, appropriate for the freshman level, to determine the flow of electrons to oxygen along the electron transport chain. States that living organisms resemble fuel cells and develops calculations for determining power output. (GS)

Examined the role of health beliefs in diabetic regimen adherence and metabolic control. Health beliefs accounted for a statistically significant portion of the variance in both. For older patients perceived benefits of adhering to the diabetic regimen was most significant. For younger patients costs figured prominently in adherence and perceived…

Discusses some of the problems associated with teaching abstract concepts in biochemistry because of the inability to provide visual aids. Suggests the use of metabolonograms as analogies in teaching certain concepts. (TW)

Discusses the role of the small intestine in the digestion and absorption of carbohydrates and proteins. Indicates as outdated the view that these materials must be broken down to monomeric units before absorption and that the gut secretes a mixture of digestive juices which brings about absorption. (JN)

An approach for rigorously treating the metabolic pathways as a series of progressive levels emphasizing the integration of knowledge at each level is presented. The method stresses the relationship between diverse material and approaches to lend coherence, comprehension, and retention to the study of the metabolic pathways. (JN)

Discusses the relationship of taste and smell to ingestion, digestion, and metabolism. Indicates that the response of these physiological systems can be chemical specific and that chemical senses may play different roles in regulating diet during nutrient deficiency and during nutrient surplus situations.
