As a result of human beings' activities to dominate nature and transform it for their own benefit as they continue to advance in science and technology, environmental problems such as climate change have become the biggest threat faced by the biosphere in the current century. One of the biggest problems of humanity today is the scarcity of water…

Recent studies have reported a growing trend of using student-generated diagrams for assessment in science teaching and research. However, many educators tend to use diagrams to explore students' perceptions of scientists and their work rather than explore conceptual understanding of abstract concepts. In this study, we used diagrams to…

In recent years, chemistry educators are increasingly adopting immersive virtual reality (IVR) technology to help learners visualise molecular interactions. However, educational studies on IVR mostly investigated its usability and user perceptions leaving out its impact on improving conceptual understanding. If they evaluated students' knowledge…

The formation of waves as used for surfing close to the shore is described and explained, and linked to other wave topics that are covered in school science. Of course, there are differences because the wave activity is influenced by many factors, such as the weather and the shape of the shoreline, which make the wave patterns much more…

This study introduces a methodological framework for integrating STEM technologies into secondary school chemistry through project-based learning. The research aimed to boost students' interest and engagement in chemistry by involving them in a scientific project called "Water Purification Methods." Eighth-grade students from Kazakhstani…

Siphons have been used since ancient times to transport water between two points over an intervening barrier higher than the water source. This paper describes a practical application of a siphon to provide fresh water to a remote island community in the Solomon Islands. The siphon was constructed from 25 mm diameter blue line polyethylene pipe.…

The aim of this study was to compare the 5E learning model with traditional learning methods in terms of their effect on students' conceptual understanding of water subtopics. The participants of the study were grade 8 students of 2021 academic year. While 27 of them were randomly assigned to the experimental group, the other 27 were assigned to…

Topics associated with the chemical sciences form a significant part of the curriculum in science at the primary school level in the U.K. In this methodology paper, we demonstrate how a wide range of research articles associated with the chemical sciences can be disseminated to an elementary school audience and how children can carry out…

This study examines the development of the concept of the ecological niche among 10-11-year-old students and their ability to use this concept to give their opinions on the socially relevant and controversial possibility that wolf populations might be established in the mountains surrounding the school. A total of 21 elementary school students…

A simple, repeatable and inexpensive laboratory practice applied to teach and discuss aquatic metal pollution and oxidative stress detoxification mechanisms through biomarker analyses, as well as important ecotoxicology concepts, is presented herein. It has been implemented in a university in Brazil to both undergraduate and Master's and PhD…

We present ideas about concepts underlying climate change, held by students in years 9 and 10. Misconceptions about climate change are common among students, and may be due to misconceptions about underlying concepts. To investigate this, we developed the Climate Change Concept Inventory (CCCI), and trialed it with 229 students; corroborating…

A laboratory exercise was developed for the study of the effect of three cations (Al, Ca, and Na) on the flocculation and dispersion of soil particles. The exercise was designed for Soil Science undergraduate students in the second-course in the Agricultural Engineering and Environmental Sciences department at the University of Vigo. The students'…

The territory of Indonesia is dominated by vast oceans. Therefore, Indonesian citizens should be equipped with a deep understanding about sea currents and sea pollution. This study aims to identify the conceptions held by pre-service primary school teachers about both sea currents and sea pollutant migration. The study also aims to identify…

We present a critical discussion of how chemistry textbooks treat the electrolysis of water and aqueous salt solutions, based on a survey of general chemistry textbooks in English and Korean at secondary and tertiary levels, also informed by the historical background of 19th-century debates. English-language textbooks present various and…

This study was prepared to investigate prospective biology teachers' cognitive structures related to "water". As the research design of the study, the case study was applied. The data were collected from 44 prospective biology teachers. The free word-association test, the drawing-writing technique and the semantic differential attitude…
