Sustainable use of freshwater is globally important. Yet implementation of changes in water management is poor, especially in developing countries. This is an indication that, despite our dependence on freshwater, we lack awareness of the need to protect these systems. Here we promote dragonflies as an easy-to-learn tool in environmental education…

The article suggests art and ESP integration in a foreign language classroom at technical university. The authors describe five parts of the art and ESP integrated project "Water treatment" developed for teaching chemical engineers ESP at tertiary level. Each part of the project combines art such as poster drawing, writing a poem,…

The Clark Fork Watershed Education Program (CFWEP) goals are: (a) increasing students' understanding of the nature of ecological impacts within their watershed as related to historic mining damage; and (b) increasing students' sense of stewardship of newly restored landscapes. Data from 2012 to 2016 were evaluated for student knowledge gains (46…

Children's everyday activities enable them to learn some science even before entering preschool education and children bring these ideas with them when entering education settings. Some of these ideas, or else mental representations, may not be compatible with what is generally accepted by the scientific community. This paper presents the results…

In this paper we describe the results of some experiments about using surprising physics demonstrations, presented as magical phenomena followed by scientific explanations, for introducing physics topics in several teaching contexts. All the demonstrations have been designed to be implemented with easy to get and cheap materials, so that students…

What's in Our Waters Jr. (WOW Jr.) is an environmental outreach program designed to teach fourth grade elementary students about watershed protection. This program is unique because of the partnership that brings together students, teachers, scientists, and water resource professionals to promote science education and environmental stewardship in…

This article describes how by using three points to make a line and comparing the graphs for water and oil, students can mathematically demonstrate that Gatorade dissolves in water much more readily than in oil. Students can also use units to understand and solve a multi-step problem by observing the color of each solution, making conductivity…

Under certain conditions a body of hot liquid may cool faster and freeze before a body of colder liquid, a phenomenon known as the Mpemba Effect. An initial difference in temperature of 3.2 °C enabled warmer water to reach 0 °C in 14% less time than colder water. Convection currents in the liquid generate a temperature gradient that causes more…

We have observed a nice example of chromatic dispersion due to refraction in water, in the form of color fringes bordering the black stripes that exist at the bottom of a swimming pool. Here we give a qualitative description of the phenomenon, explaining the role of the black stripes and the dispersive index of refraction of water.

This research aimed to assess the composition of total dissolved nitrogen (TDN) species, particularly dissolved organic nitrogen (DON), over the traditional wastewater treatment operations in three biological nutrient removal (BNR) wastewater treatment plants (WWTPs) in Jordan. It had been found that the DON percentage was up to 30% of TDN within…

On July 19, 1969, Senator Edward Kennedy drove his vehicle off a low bridge on Chappaquiddick Island in Massachusetts. The vehicle sank in 2.1 m of water, coming to rest on its roof. According to Kennedy's version of events, he managed to escape from the submerged vehicle without injury, but his female companion, Mary Jo Kopechne, drowned without…

Despite being increasingly popular within broader educational discourse, place-responsive pedagogy is less apparent in science teacher education. This paper investigates the perspectives of pre-service teachers in a science education course informed by place-responsive pedagogy in a Bachelor of Education (primary) program at an Australian regional…

As part of the educational process, it is currently difficult for a teacher to engage students for the amount of information that is available all around us today. Therefore, it is necessary to choose appropriate methods and actively prepare various teaching aids that can motivate students, arouse interest in self-study and thus educate them. The…

As societies search for ways to deal with increasing environmental issues due to human impacts, the urgency increases for public schools to produce graduates who are environmentally literate and thus equipped to deal with the environmental issues that will face upcoming generations. This research presents a case study that examines the impact of a…

The public's understanding of climate change has been plagued by poor communication, misinformation, and disinformation. Fortunately, there is a growing body of research on effective climate change communication strategies. A popular element of science communication is documentary film. Educational films produced for museums, planetariums, and…
