Purpose: This research aimed to: (1) measure out the validity level of the developed Student Worksheets, (2) explain the students' responses and learning motivation in using Higher Order Thinking Skills (HOTS)-based worksheets, and (3) find the effect of the HOTS-based worksheet on learning outcomes. Methodology: The study employed the Research…

By building a schlieren optical system, the visualization of a 40 KHz sound wave is realized. By using the schlieren system, the demonstration of acoustic reflection, interference and diffraction can be easily realized. At the same time, the visual acoustic field provides another simple way for the measurement of sound velocity. In this paper, the…

In this kindergarten lesson about pushes and pulls, the authors used the SHARE strategy to embed effective questions throughout each phase of the 5E learning cycle (Engage, Explore, Explain, Evaluate, Elaborate). The thoughtfully worded and open-ended questions shared in this article can help students generate ideas and focus their thinking…

During their first physics courses, most students struggle with mathematical concepts that are used but not fully understood, for example, the appearance of infinity in introductory physics exercises. In many cases, these concepts are critical to understanding the underlying physical phenomenon. Typically, most books do not place much emphasis on…

A common procedure when conducting physics experiments is to repeat a measurement several times to calculate the mean and standard deviation. That might be the only instruction we give to students as a means to minimize random errors. However, that technique does not guarantee that the answer will be correct. It might give the same wrong answer…

This November marks another anniversary of the collapse of the Tacoma Narrows Bridge, an example appropriate to introductory science or physical sciences courses from grade school to university. The purpose of this brief submission is to add an element to this story, which, despite having been mentioned before, has not received the prominence it…

We have investigated the motion of water flow through glass tubes of different shapes by calculating the value of the Reynolds number denoted as Re. We know that at a given flow rate the value of Re determines the type of flow being classified as laminar, transitional or tubulent. The dependence of Re in different configurations of glass tubes as…

In the violin, the fundamental air cavity mode (the A0 mode) is associated with the sound radiated by the f-holes. The dependences of the sound velocity of the A0 frequency on gaseous temperature and mass were investigated. It was found that the frequency of the A0 mode changed, depending on the molecular weight and the temperature of the gas…

Contemporary views on physics education in high schools promote the need for students to develop their conceptual understanding about physics phenomena. However, teaching in this way requires specialized professional knowledge and for pre-service physics teachers, such knowledge needs to be scaffolded and developed. A strategy to support this…

Kundt's tube is a popular experiment commonly used in schools, in which standing sound waves are made visible inside a glass tube. A fine powder is stirred up in areas of high sound particle velocities, so that one can measure the wavelength of the sound waves by examining the patterns created. In this way, the 'invisible' can be made visible.…

The IOLab is a versatile and inexpensive data acquisition device in a cart that can roll on its three wheels. It has numerous sensors for a variety of physical quantities. We adapted "RealTime Physics, Module 1: Mechanics" active learning labs for use with the IOLab. We tested these labs both on campus and with distance learners at…

Argumentation as a scientific practice has largely been examined along an epistemic and/or dialogic perspective in science education research. Both perspectives have sidelined the use of real material objects that are indispensable for scientists to construct arguments about the natural world. To address this gap, this article investigates how…

This work presents the design of an inexpensive electronic system to measure water temperature and generate an experimental data set used to verify the fitting between experimental and theoretical curves of a water-cooling process. The cooling constant is computed with three different theoretical methods to check their efficiency and this approach…

Light spectrum dispersion is an exciting subject in science because of its beautiful atmospheric colour phenomenon which attracts students. However, to see the phenomenon is not easy since it needs a spectrometer, which is commonly expensive. Therefore, the present study aims to describe a low-cost spectrometer for investigating lighting spectrum…

Air pollution is one of our day's significant reasons for human health problems and affects every community throughout the world. Monitoring air pollution is a key aspect of raising awareness and pollution mitigation approaches followed by different nations. This paper targets to develop a low-cost Internet of things-based embedded system to…
