The Upper Taieri River catchment is an arid area in the Otago region of the South Island of New Zealand faced with intensifying agriculture production. This article describes an assessment of the education/communication processes of a water resource management project and the effects on farmer beliefs/attitudes and targeted outcomes. Lessons…

It is important to let students see the value of mathematics in design--and how mathematics lends perspective to problem solving. In this article, the author describes a water-service challenge which enables students to design a water utility system that uses surface runoff into an open reservoir as the potable water source. This challenge…

The case study discussed in this work is used at the chemical reaction engineering course, offered in fifth-year of the chemical engineering undergraduate program at National University of Mar del Plata (UNMdP). A serial-parallel reaction system based on the anaerobic degradation of particulate-containing potato processing wastewater is presented.…

When an ice cube floating on water in a container melts, it is said in some textbooks that the water level does not change. However, as pointed out by Lan in a recent work, when the buoyant force from a less dense fluid resting above the waterline is taken into account, one should expect a detectable "increase" in the volume of water. Here in this…

The motion of charges around a centrally charged object is often compared to gravitational orbits (such as satellites around planets). Recently, a video taken by astronaut Don Pettit onboard the International Space Station shows water droplets orbiting a charged knitting needle. Here we attempt to model this motion and estimate the charges on the…

Consider the waste streams generated in schools and universities. So what is in the typical used water generated in schools and universities? It is typically about 99 percent water, with the remaining 1 percent mainly made up of organic compounds. Used water contains nutrients such as nitrogen and phosphorous. When one judges it on its quality, it…

The University of Alabama at Birmingham (UAB) has experienced rapid growth in the last decade. In addition to educating over 17,000 students annually, UAB is a major research facility and academic healthcare center. Due to growth and expansion, UAB requires more and more water to sustain operations. The central chilled water system serves over…

The study aimed at investigating the effect of using cartoons on developing grade four students' awareness of water issues. It also aimed at examining their attitudes towards using cartoons in social studies lessons. An experimental design was used with pre-posttest. The experimental group consisted of (33) male and female students while the…

Even though density is taught in middle school, high school students often struggle to understand that the density of a substance is consistent regardless of amount. This is because many high school students know density = mass/volume, but do not have the conceptual understanding necessary to explain density-related phenomena. The scaffolded…

Forestry and environmental science students enrolled in a one credit hour freshman seminar course participated in a land management evaluation and water quality sampling excursion using canoes and water sampling equipment. The purpose of this assessment was to engage students with hands-on, field based education in order to foster connections to…

Extension Master Gardener Volunteers (EMGVs) are recruited and trained to answer questions and diagnose gardening problems for the public. Most states have developed an EMGV Manual for use in the initial training. Thirty-two EMGV Training manuals from across the United States were reviewed for form and content. While many of the manuals have…

This report, which has been developed through a partnership between the African Union Commission (AUC) and UNICEF, aims to: (1) track the progress that African nations have made in education, especially in relation to Sustainable Development Goal 4 (SDG4) and the Continental Education Strategy for Africa (CESA) goals; (2) identify the challenges…

Environmental protection is a sensitive issue in the world today. Erratic weather changes have been witnessed in many parts world including Kenya. Indeed, scholars and critics have argued that human beings are a major contributing factor to destruction of nature through industrialization, farming activities, transport, deforestation, wildlife…

The aim of this research is to investigate student science teachers' opinions about the causes of degradation of ecosystems and the effects of such degradations on the environment. This research focuses on the following questions: What kind of descriptions do student science teachers ascribe to the reasons of degradation in ecosystems? What are…

Purpose: The purpose of this paper is to inquire about the applicability of the concept of granularity to the necessity of future research or--as often called in the European Union--forward looking (FL). After theoretical deliberation, it uses a planned world-wide information system as a case study for applying the notion of granularity regarding…
