Microfluidics has attracted widespread interest in the fields of chemicals, materials, pharmaceuticals, biology, etc. Integrating low-cost automation based on open-source hardware/software to improve lab security and reduce time consumption is demanded in microchemical processing. In this work, we developed a "do it yourself"…

This study investigates the influence of inquiry-based laboratory activities on the understanding of heat concepts and the self-efficacy beliefs of pre-service primary teachers. Recognizing that both scientific literacy and teaching efficacy are critical for effective science education, this research aims to determine how inquiry-based laboratory…

A collection of four activities for science outreach events was developed to teach middle school students about the temperature dependence of scientific phenomena. Procedures are described for four interactive demonstrations on phase changes, fluorescence, viscosity effects on diffusion, and conductivity. Each hands-on activity helps students…

Kids are drawn to dolls and dump trucks, and crashing the two together might just be a child's favorite pastime. Who knew such a simple pleasure could serve as an accessible, compelling phenomenon for instigating investigations of force and motion. With a few inexpensive materials straight out of the toy box (literally, a doll, a dump truck, a…

The COVID-19 pandemic has significantly affected teaching processes worldwide, particularly in laboratory-intensive courses. To adapt, online experiments have been implemented globally. In response, educators at the Department of Chemistry, Chulalongkorn University, developed a Lab@Home chemistry experiment for their general chemistry lab course…

Students have several misconceptions about thermodynamics. However, an understanding of basic concepts in this branch of physics remains fundamental to explain thermal phenomena. The purpose of this activity was to extend students' conceptual understanding of heat, temperature, energy, and thermal insulators and conductors. Two groups of students…

Electromagnetic (EM) waves are indispensable in modern telecommunications. Despite their essential role in modern technology, EM waves are considered to be an abstract concept by many students. In this activity, an inexpensive two-coil system was constructed in a teaching laboratory and used to demonstrate information transfer by non-sinusoidal EM…

Water is a meaningful context for children to engage in inquiry, and to acquire and use science and engineering practices, such as developing spatial thinking and early concepts of water dynamics. This book shows teachers how to provide children with opportunities to engineer water movement through pouring and filling containers of various kinds…

The forest school approach to nature learning has gathered momentum in the UK and across parts of Europe including Scandinavia for well over 50 years. In other contexts that include Canada, China, New Zealand and Australia, nature-based early childhood education and care settings, influenced by European forest school approaches, are in a rapid…

Electrophoresis is integral to analytical and biochemistry experiences in undergraduate education; however, fundamental principles of the method are often taught in upper-level laboratories through hands-on experiences. A laboratory activity is reported that teaches the concepts of electrophoretic mobility and electroosmotic flow. A single…

Kinesthetic experiences in the classroom seek to engage students by muscle movement, touch, or some form of physical activity. In this article, I describe an active learning session wherein students develop a qualitative understanding of center of mass and support forces using their sense of touch. The set of activities detailed here is based on a…

Electricity is an integral part of daily life. Children, like adults, infer the effects of electrical conductivity. They see the illumination of a lightbulb or feel the emission of warmth from an electric stovetop but may not understand the role electrical circuits play. Focusing on the concrete aspects of electrical energy transfer helps improve…

The purposes of this study were: To examine the effects of low-cost mini science experiment kits on Thai 6th graders' science learning achievement; To investigate how these kits impact Thai 6th graders' Science process skills; To explore their influence on Thai 6th graders' scientific mindset The participants were 111 sixth-grade students from…

Hydrogel is an interesting topic in polymer chemistry, which is closely related to daily life and advanced technology. In this paper, we report an activity to deliver hydrogel chemistry into middle school classrooms by undergraduates as a bridge between professors and students. During the activity, undergraduates act as a bridge to receive…

Wave optics is a mandatory part of Croatian secondary school physics curriculum for students in the final year of secondary school (age 18-19). Many physics education research studies have shown that it is a difficult physics topic for both university and secondary school students. An inquiry-based teaching sequence on wave optics, designed for…
