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…

Green Architecture for Sustainable Communities (GASC) was a joint event organised by Dutch and Vietnamese universities with the aim of boosting sustainable development in the built environment of Vietnam. As a key activity of the event, the international student design workshop focused on renovation of typical Vietnamese row houses -- aiming…

A common problem in many schools is the lack of equipment and materials in their science laboratories due to both limited budget available to the school and high maintenance cost of the lab. The latest technological advancements provide great opportunities for schools to go over the budget and cost issues by using 3D virtual learning environments…

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…

We evaluated an emerging smartphone application, iNaturalist, to increase taxonomic identification and engage first-year undergraduate biology majors in outdoor laboratories of aquatic ecosystems (stream and lake ecology) and terrestrial ecosystems (tree and leaf litter ecology). Labs involved identifying organisms using both standard field guides…
