For the start of a secondary school level lesson series on quantum computing, we designed a hands-on modeling activity where students construct a model diamond lattice with a nitrogen vacancy (NV) defect. NV centers find application as qubits and sensitive magnetometers. This activity aims to help students visualize the structure of such NV centers within the diamond lattice, making the subject matter more tangible. The activity has proven to be challenging but feasible. It features both collaborative and competitive elements thereby surely creating an energizing buzz in the classroom.

Seeing connections between different areas of physics is a good way to teach physics. In the orbit of a planet, there is a continuous interchange between gravitational potential energy and kinetic energy with the sum being constant. This is essentially the same physics as a mass on the end of a spring, or a pendulum. In this paper, equivalent spring constants are calculated for planetary orbits and the pendulum equation used to derive Kepler’s third law.

The fruits of many plant are carried and flowers are also swayed by the wind. If the flow of air around plants can be visualized, the science behind it will be interestingly illustrated. In this study, the gas flow around cherry blossom fruits, clover flowers, maple seed propellers, and dandelion pappi as spherical and propeller-shaped samples is demonstrated using a Schlieren optical system and a high-refractive-index gas. The observed gas flow corresponding to the sample shape was well characterized by fluid dynamics features such as the Coandă effect. The results of experiments in which the flow of gas around plants is visualized are useful as a scientific education material for fluidics and optics.
许多植物的果实会随风飘落，花朵也会随风摇曳。如果能将植物周围的气流形象化，就能有趣地说明其背后的科学原理。本研究利用 Schlieren 光学系统和高折射率气体，展示了樱花果实、三叶草花、枫树种子螺旋桨和蒲公英 pappi 等球形和螺旋桨形样品周围的气流。观察到的与样品形状相对应的气体流动具有流体动力学特征，如 Coandă 效应。将植物周围气体流动可视化的实验结果可作为流体学和光学的科学教材。

On a chilly evening, a practical challenge was posed to 2nd level students taking an extra-curricular math class: Imagine a household cylindrical oil tank lying on its side. How could we determine how much heating oil remains in the tank? In this paper, we ask students to engage in mathematical deduction to devise methods for approximating a solution to this intriguing engineering problem. The only tools that we have access to are measuring tape, and a long clean stick, so resourcefulness becomes key. We establish a mathematical relationship between the parameters that we have access to measure and the volume of oil that remains in the tank. Expanding the scope, we encapsulate this solution within a Jupyter Notebook (Python), allowing for the calculation of oil in any cylindrical tank.

We aim to highlight the importance of using Huygens’ geometric model when instructing high school students about light. To achieve this, we conducted a research study on teaching lightwaves in Morocco’s secondary schools. We investigated how the place of the lightwave in this teaching affects understanding its basic concepts. We carried out a two-dimensional analysis to examine the place of the lightwave in the high school physics curriculum. We administered a test to assess the conceptual understanding of secondary school and university students. The analysis of the curricula revealed several shortcomings in the teaching of geometrical and wave optics. Furthermore, the assessment of conceptual understanding revealed that a significant proportion of students have misconceptions about the wave concepts of lightwaves and that these misconceptions persist throughout their higher education.

This is a documented reflection that seeks to characterize an alternative conception of the ‘mathematization of physics for teaching’. The reflection was made on the academic production of the research group ‘Teaching and learning of physics’. This group has posed a sequence of research questions has been raised to find out how physics teachers understand the relationship between physics and mathematics in the physics teaching process. In 2003 they studied the idea of ‘mathematical beauty’ in the early days of quantum mechanics, suggesting that there would be a difference between the way scientists assume the physical/mathematical relationship and the way physics is taught. In 2010, they wondered if there would be research in this field that would allow transformations in teaching focused on equations as the set of mathematical–physical relationships, finding that there are at least three trends. In 2019, they verified that despite the research in the literature, many students continue with the same reductionist idea about this relationship. In 2020, they made a proposal, showing a possibility of educating the teacher’s thinking for new understandings in this regard. The main conclusion is that it is possible to develop mathematization processes in the classroom from three specific phases that educate scientific thinking. The first phase tries to make the student aware of the existence of phenomenology and describe it. The second phase educates the study of nature in a systematic way, building the meaning of the organization of a physical system. The third phase promotes explanation and argument so that students achieve an explanatory model. These phases are configured as a criterion to guide the sequence of activities in a class, a set of classes or a complete course and have been worked on and tested in ‘physics didactics’ courses in a physics teacher training course.

Voltage regulators, the most common application of Zener diodes, are included in many electronic devices we use in our daily lives. Therefore, students need to learn about regulators to understand the place of Zener diodes in modern electronic technologies. This study focuses on a microcontroller-based experiment that can be used to teach line and load regulation with real-time graphics. The main advantage of the designed experiment over its classical equivalent is its ability to display autonomous and real-time data display. It also eliminates the problem of determining the load resistance, which is the main difficulty of the classical experiment.

By measuring the period of oscillations, a suspended bob is used to determine the local gravitational acceleration g. When modelling the system as either a simple pendulum or a physical pendulum, the measured g is found to be less than the accepted value as the size of the bob increases. With a given bob’s size, the simple pendulum measures g to be slightly higher than the physical pendulum does.
