This book provides five instructional units on groundwater. Units included are: (1) "Where's the Groundwater?" (describing the concepts of a saturated zone, water table, hydrologic cycle, recharge and discharge, core of depression, subsidence, and saltwater intrusion); (2) "How Does It Travel?" (discussing porosity,…

Every year, Americans spend billions of dollars on bottled water. They purchase a bottle from the vending machine or buy a case at the grocery, no longer considering the water that's freely available from their taps. As consumers and as citizens, however, Americans should pause to study the personal and public consequences of this choice. In this…

The purpose of the present study was to investigate students' conceptions of the hydrologic cycle and to examine whether these conceptions vary by grade level and community setting. This study was descriptive in nature and reflected a cross-age design involving the collection of qualitative data from 1,298 students from the Midwest, USA. These…

We challenged an Aquatic Biology class to find a way to access, observe, and record aquatic habitats and organisms without causing disruption. Using off the shelf components the class was guided in the design and assembly of a remote controlled, video broadcasting, data collecting, floating vehicle based on a molded goose decoy. GOOSE-CAM or…

As an experimental project proposed to students in fourth year of university, a viscometer was developed, consisting of a small magnet levitating in a viscous fluid. The viscous force acting on the magnet is directly measured: viscosities in the range 10-10[superscript 6] mPa s are obtained. This experiment is used as an introduction to complex…

In pursuance of one of the goals of the new South African curriculum to integrate science with Indigenous Knowledge Systems (IKS), this study, which forms part of a larger study, is concerned with determining teachers' and learners' conceptions of a number of familiar natural phenomena. Several recent studies have indicated that: (1) learners do…

Increased energy costs and a move toward environmental stewardship are driving many organizations, including universities, to engage in awareness efforts to reduce both energy consumption and their carbon footprint. The purpose of this paper is to determine whether organizational programs aimed at energy and environmental awareness have a…

Provides background information on many topics related to water. These include the water cycle, groundwater, fresh water, chemical wastes, water purification, river pollution, acid rain, and water conservation. Information is presented at an elementary level. (JM)

Fruit batteries and saltwater batteries are excellent ways to explore simple circuits in the classroom. These are examples of air batteries in which metal reacts with oxygen in the air in order to generate free electrons, which flow through an external circuit and do work. Students are typically told that the salt or fruit water acts as an…

A favorite destination for kids and adults alike, waterparks provide hours of family enjoyment. From an indoor hotel pool with water slide and spray hydrant to acres of outdoor water play opportunities like those found at Disney's Blizzard Beach and Typhoon Lagoon, plenty of fun is ready at hand. Waterparks vary in size, venue design, variety of…
