We investigated the effect of short-term teaching (3 weeks) using image analysis on gymnasium/secondary school students' (ISCED3A) skills (science process skills, SPS) and knowledge using Fiji (ImageJ) software. The theoretical teaching was combined with IT-based education (measurement of the area or signal intensity on photos from scientific…

In this article, we propose a simple and accessible model of a magnetic levitator fitted with a Hall sensor. This model also allows to determine the magnitude of the magnetic field within the levitator working volume. Students can also compare the experimental magnetic field values to reference values in magnetism textbooks. This Arduino-based…

The video of a free-falling object was analysed in Tracker in order to extract the position and time data. On the basis of these data, the velocity, gravitational potential energy, kinetic energy, and the work done by gravity were obtained. These led to a rather simultaneous validation of the conservation law of energy and the work-energy theorem.…

We describe a simple STEM project for students to learn to measure atmospheric pressure by using a sensor of the type BMP180 together with the Arduino electronic platform. The collected experimental data, together with simple experiments, can be used to study the different pressure units and the relationship between pressure and force. Also, they…

We show that the gravitational acceleration g near Earth's surface can be easily determined with high accuracy by conducting the usual free fall experiment in high school or college physics laboratories. Unlike the conventional method of data analysis that uses formulas without taking air resistance into account, we consider the effect of air drag…

This paper describes the development of a light polarization experimental apparatus for a remote laboratory. The apparatus had been developed by controlling the analyzer rotation using a stepper motor controlled via the Arduino. Device control and data acquisition applications were developed with LabVIEW which provides remote control panel…

This study has proposed a simple method to show the convective heat transfer. The object in this study is an air conditioner (AC) as a simple case of convection. In addition, AC is also easy to find in the class because most classrooms in Indonesia installed AC. Usually, a visualization needs special software (i.e. MatLab or others) and good…

Teaching materials used in distance education are generally obtained from the internet as ready-made by teachers. Materials such as simulation, animation and presentation are usually limited to the frame drawn by the creator and do not allow changes outside this limit. In addition, many of these types of materials do not have a feedback mechanism.…

Described here is a well established opensource geophysics project to monitor atmospheric infrasound 24/7. It employs a modern digital, I[superscript 2]C enabled differential pressure sensor--unlike the older analog devices more commonly used. Python software automatically uploads plots whilst data is stored in standard ".mseed" format…

Here, we present an interdisciplinary educational project intended for high school chemistry that is focused on the establishment of a mathematical model to describe the relationship between conductivity and concentration, while linking chemistry to mathematics with the help of computer software. The project was designed to help high school…

The interactive generation of chemical-structure diagrams is an integral activity in the study of chemistry as well as in professional chemistry environments. For educational purposes in particular, the existence of suitable software tools free of charge is of great importance. Although a number of free chemical-drawing applications are currently…

As soon as children can see, they observe that objects fall freely. From a young age, we spontaneously construct interpretative models to understand this everyday phenomenon. Over the last three decades, numerous experiments have been developed to help students understand physics concepts regarding free fall. Although there are many…

The purpose of this study is to investigate the effect of augmented reality and mobile application supported instruction on students' academic achievement, attitude towards astronomy, anxiety and motivation towards learning science in the "Solar System and Beyond/Earth and Universe" units in seventh grade Science lesson. In the study,…

This work combines laboratory quantitative analysis of colored solutions and common devices for digital imaging (digital or web cameras or mobile phones, i.e., smartphones). ColorX software, specially designed for this study, was used for data collection and analysis in order to calculate concentrations of colored solutions from measured RGB…

This paper proposes an experiment in which students build microdevices for conveniently electrolyzing water and use image recognition and processing technology to measure the volume of gas generated during the reaction in a noncontact way. Taking advantage of three ratio relationships between (i) gas volume and the area of bubbles, (ii) the…
