Describes activities that will help students calculate the volume of water carried by a river or stream and how to measure the amount of water wasted by leaky faucets. (MDM)

Describes experiments designed to investigate the cooling rate of microwave-boiled water as compared to that of stove-boiled water. Concludes that within experimental limits, microwave-boiled water and stove-boiled water cool at the same rate. (JRH)

Using the movie Star Wars as inspiration, an activity is presented to introduce students to water's cohesiveness and how the surface tension of water can be disrupted. (MKR)

Presents a Project WET water education activity. Students are introduced to the concept of watersheds by collecting data about water flowing over their school grounds. Helps students understand that they live and attend school within a watershed. (LZ)

Demonstrates the mathematical nature of a pollution problem in a marine environment. Includes reproducible student worksheets. (11 references) (MKR)

Provides a "template" for how a stream ecosystem functions. Discusses the physical and chemical factors of geology, light, current velocity, temperature, and energy sources. Describes functional groups of aquatic insects and the River Continuum Concept, a model of interaction that explains the spatial occurrence of aquatic insects. (LZ)

Discussed are the effectiveness of the current international regulatory framework to protect the marine environment, the need for more stringent maritime regulations fostered by an increased popular awareness that this current framework is outdated, and the strategies deemed appropriate to assimilate the "total environmental view" within…

Explains the nutritional requirements of children and adolescents, and the physiological roles of the major nutrients. Details the nutrient needs of young athletes, including pre- and postgame meals and fluid replacement. Discusses eating disorders and obesity. Advocates a diet rich in complex carbohydrates. (BC)
