Thomas Young (1773-1829) is best known in the physics community for his double-slit experiment demonstrating the wave property of light and for his work on the tensile properties of solids (Young's modulus). His reputation as a physicist was built almost entirely upon a short, three-year period (1801-1803) of intense work as an instructor in…

Germinating a seed is presumably the first experiment made by a child in his life. So, it has an important place both in child's scientific experience and understanding. Despite the significance of the experiment, the literature indicates that students possess various misconceptions related to the concepts of seed and seed germination. So, it is…

Safe and high-quality water is essential from both the health and environmental perspectives. Water quality is so important that the United Nations has included water in the 17 Sustainable Development Goals of the 2030 Agenda for Sustainable Development. Thus, the adequate control and treatment of water are necessities. These tasks must be…

This paper seeks to investigate how students' performance in Chemistry can be enhanced by using kitchen resources in Calabar. The kitchen resources used included a piece of white paper, a swab, lemon juice and candle. These were used to show that paper cellulose was oxidized by flame due to the catalysis of lemon juice acid. Other materials used…

This article presents a series of activities that not only help learners discover the waggle dance--a behavior performed by scout bees to communicate the location of a flower patch--and its purpose but also introduce circuitry, engineering, and energy transfer using hands-on, inquiry-based strategies. These activities were conducted in a…

We report on a distance learning experimental project for chemistry-major students on the synthesis of ethyl dodecanoate (C[subscript 11]CO[subscript 2]Et), a model for biodiesel, considering green chemistry principles. Thus, we employed a "recyclable acid catalyst" (an ionic liquid) and used chemometrics and microwave heating (MW) to…

This high school life science unit introduces students to the intersection of science, economics, geography, and culture through the current practices of palm oil cultivation in the tropics. For this article, the authors travelled to Sabah Province, Malaysia, to visit palm oil plantations, conduct interviews, and collect resources to help students…

Newton's cradle is a well-known physics toy that is commonly used by teachers to demonstrate conservation laws in mechanics. It can also be used to investigate the physics of colliding objects, by recording motion of the balls on video film. Various experiments are described using 3-ball and 5-ball cradles, showing how different types of collision…

In recent years, with the more powerful functions of smartphones, the use of sensors integrated by mobile phones as an auxiliary tool for physical experiment teaching has become more popular. Combined with the related mobile phone apps, people easily can develop and expand the physical experiment contents of mechanics, optics, acoustic phenomena,…

Martin Wagenschein's ideas of prioritising phenomena in making sense of science processes have influenced the German "Lehrkunstdidaktik" (art of teaching) approach. This article sketches a "Lehrkunstdidaktik" teaching unit inspired by Michael Faraday's "Chemical History of a Candle." It shows how primary and lower…

The author writes about taking on the role of Science Coordinator, changing expectations, and raising the profile of science in her school.

In response to the call for an increased emphasis from the American Chemical Society on including macromolecular studies in the undergraduate curriculum, a supramolecular-themed experiment was designed for undergraduate-level organic laboratory courses that provides a convenient platform to study physical behaviors of supramolecular assemblies.…

Students in introductory college science courses often have a simplified understanding of the scientific method. To introduce students to the complexity of the scientific process and the value of empirical observations, I implemented a semester-long assignment that required introductory-level college science students to build and calibrate weather…

This article describes an inquiry science lesson that was sparked by a child's question. In this school a science specialist (author 1) team teaches science with the kindergarten class teacher (author 2) for 1 hour per week. The class teacher integrates science at other times during the week. To foster the kindergarteners' interest about a science…

In this article, physical quantities related to the motion of a parachute system in the framework of Newton's law of mechanics guide an informal approach to the mathematical concept of function. Furthermore, a graphical simulator that enables visualization of the fall of object-parachutes system is presented. The article is aimed at students and…
