In this paper, we introduce a three-dimensional demonstration for the refraction and reflection based on total internal reflection of light in transparent media, and discuss the reasons for the formation of circular bright areas and circular shadows, respectively. Then, according to the relationship between the diameter of circular shadows and bright areas, the depth of water, and the thickness of the polymethyl methacrylate plate, we described a teaching experiment based on total internal reflection of light to achieve refractive index measurement of transparent liquids and solids. The refractive index of transparent media measured using this method is in good agreement with reported data.

This paper presents an astronomical analysis of the van Gogh drawing ‘Bank of the Rhone’ to determine the possible dates of its creation. By examining the position of the sun depicted in the drawing and comparing it with the actual sunset positions at the location in Arles, France, a range of dates is derived that differs from the accepted historical dating of the work. The study demonstrates the potential of using interdisciplinary approaches that combine art and astronomy to gain new insights into artistic works. The analysis also serves as an engaging exercise for students to explore the intersection of science and art.

The present study explores the impact of LAB Disc technology on enhancing physics education among gifted ninth-grade students in lyceums. The study employed a quasi-experimental design to examine students’ academic performance and engagement levels in two groups: an experimental group that utilised LAB Discs and a control group that received conventional physics education. To ensure comparability in baseline understanding of the subject, each group consisted of 30 ninth-grade students who were selected based on their academic prowess and enthusiasm for physics. The utilisation of LAB Discs, versatile devices equipped with diverse sensors for instantaneous data gathering and examination, was designed to offer a more engaging and experiential learning encounter. The study’s methodology employed a combination of quantitative and qualitative data collection techniques, including tests, surveys, interviews, and classroom observations. The impact of LAB Disc technology on students’ learning outcomes was assessed using an independent t-test and boxplot visualisation. The results demonstrated a statistically significant enhancement in ninth-grade students’ comprehension and involvement when utilising LAB Disc technology, as evidenced by a t-statistic of 6.522 and a p-value of less than 0.001. The boxplot analysis validated that students in the experimental group exhibited a superior median score and demonstrated greater consistency in their performance. The results emphasise the capacity of interactive educational tools, like LAB Discs, to enhance cognitive abilities and establish a more captivating learning atmosphere in physics classes at the lyceum level.

This work describes an exact radiometric model for experimental demonstrators of the detection of exoplanets by the transit method. This model generalises the calculation of the depth of occultation from the standard transit method to the case of a finite size demonstrator apparatus. Results show that, for demonstrator apparatuses of moderately small sizes, a significant accuracy improvement in the determination of the size of a planet model can be achieved using the proposed method in comparison to using the formula from the standard transit method. The radiance distribution of the star model is found to be of crucial importance, as deviations from a Lambertian radiance distribution can lead to significantly different results.

In this study, we present an investigation of how modeling with embodiment can help to learn about natural phenomena that are far from the human eye. In particular, we analyze this tool to study updated models of matter components and their interactions (particle physics) in high school. We perform a qualitative analysis where we describe the methodological procedure in detail. 71 students are evaluated according to two factors: first, if they are able to build the final scientific model. Second, their degree of autonomy in this process. We also cross-check the qualitative results with a quantitative pre-post analysis, using a test about the general knowledge of particle physics, from classical models to the new models. The results are positive in both the qualitative and the quantitative analysis.

We discuss experiments aimed at retracing some of the experiments on vacuum performed in the 17th century by Boyle and Huygens. We focus on the ‘anomalous suspension’ of water reported by Huygens in 1662. Our revisitation allows to discuss the apparent contrast between the results obtained by Boyle and Huygens. This controversy was one of the first conducted in scientific terms and offers the possibility of illustrating to the students how competitions and debates are conducted in modern science, which appears important in a period in which science is contested by antiscientific movements.

Thermal insulation of buildings is important because it has both ecological and social impacts. Most often, it is characterized by the so-called U-value. Heat transfer through walls includes conduction, convection, and thermal radiation. This leads to complex measurements and calculations for assessing the effectiveness of different insulating materials, and the usual methods are not suitable for classroom experiments. We propose a simple method for measuring the U-values of varied materials used in everyday life that can be performed in the classroom. It is based on measuring the temperature inside and outside a box, and the power, released by a resistance coil inside the box.
建筑物的隔热性能非常重要，因为它对生态和社会都有影响。隔热性能通常用所谓的 U 值来表示。通过墙壁传递的热量包括传导、对流和热辐射。这就需要进行复杂的测量和计算，以评估不同隔热材料的效果，而通常的方法并不适合课堂实验。我们提出了一种可在课堂上进行的测量日常生活中各种材料 U 值的简单方法。该方法基于测量一个盒子内外的温度以及盒子内电阻线圈释放的功率。

We have constructed a magnetic rail system that allows a superconductor to travel in a loop for a long time, similar to a maglev train. The system incorporates a Lego Mindstorms-controlled escalator that automatically cools the superconducting train with liquid nitrogen after each lap. As a result, the superconducting train is able to run continuously for over an hour. This demonstration will motivate students to learn physics and materials science.
