Many simple chemical reactions produce an audible fizz due to the formation of gases, such as oxygen, hydrogen, or carbon dioxide. A hands-on activity based on perceiving these audible chemical changes is presented. The relative quality of fizz due to the formation of gases in a chemical reaction was determined by visually impaired middle and high…

Floating and sinking (FS) is a key topic in science education, both at primary and secondary levels. The interpretation of FS phenomena, however, is challenging due to the difficulty of the scientific concepts and explanatory models involved (e.g., density, buoyancy), along with students' everyday experiences, which conflict with scientific…

Artificial intelligence (AI) technologies continue to revolutionize various sectors, including their incorporation into education, particularly in K-12 science education, which has become evidently significant. This paper presents a bibliometric analysis and systematic review that examines the incorporation of AI technologies in K-12 science…

Educational kits can improve the teaching of experimental sciences, providing an interesting strategy to be explored at home, especially during the COVID-19 pandemic. In this sense, chemistry kits based on a microscale design were developed encompassing safety, portability, efficacy, and low cost. They were successfully applied in regular classes…

To promote the integration of aesthetic education into chemistry education, this study designed activities to photograph precipitation reaction experiments with a smartphone, thereby combining experimental inquiry with artistic creation across disciplines. These activities were divided into (i) perceiving, (ii) appreciating, (iii) exploring, and…

Large numbers of U.S. students lack proficiency in science, and students from different ethnic and socioeconomic groups show disparities in science achievement. Science knowledge and skills are important for both academic and workplace success, and a variety of interventions have been developed to improve student achievement in science. The…

In light of extensive research demonstrating widespread misconceptions about electricity, this paper describes a learning study that targeted the most likely source of difficulty--failure of middle school pupils to develop a mental model that serves as a bridge between static and current electricity. During the intervention, pupils first envision…

Science education could be made more accessible to students with visual impairments through collaboration and specific adaptation in both the science classrooms and laboratories. For example, by providing simple adaptations or doing some essential modifications, students can gain experience with measuring, balancing, and weighing a variety of…

We report a series of three experiments that introduce students at different stages of their academic preparation to the medical applications of hydrogels for controlled drug delivery and wound healing. The laboratory activity bridges the fundamental concepts of chemistry (acids and bases, equilibria, solvation, and reversible esterification) with…

Inspired by the inclusion of a British astronaut on the International Space Station, explanations and demonstrations that lead to an understanding of how satellites stay above the Earth are described. This is a mixture of separate ideas that have been demonstrated successfully at a public exhibition of science-based activities. Although some…

This driven top is quite a novelty and can, with some trials, be made using the principles outlined here. This new top has many applications in developing both understanding and skills and these are detailed in the article. Depending on reader's available time and motivation they may feel an urge to make one themselves, or simply invest a few…

The science learning area of the "New Zealand Curriculum" (NZC) (Ministry of Education, 2007) requires students to learn about "features of scientific knowledge and the processes by which it is developed" and "carry out science investigations using a variety of approaches." Investigations are mostly, but not always,…

More than 60 years have passed since the work of Rosalind Franklin, James Watson, and Francis Crick led to the discovery of the 3D-DNA double-helix structure. Nowadays, due to the simple and elegant architecture of its double helix, the structure of DNA is widely known. The biological role of the DNA molecule (e.g., genetic information), however,…

The year 2014 marks the end of the United Nations Decade of Education for Sustainable Development (ESD). All educational domains and levels, including primary and secondary science education, have been working to contribute to education enabling younger generations to become responsible citizens and promote sustainable development in our world.…

A rich science learning experience not only captures students' attention but also motivates them to investigate and solve problems and investigate how scientists carry out their work. This article describes how secondary science coordinator Patrick Brown's found success teaching students the nature of science by engaging them in…
