Jessica Meir has been floating in the ISS since 14 February 2026. Artemis II just brought back four astronauts from a historic flyby of the Moon on 10 April. Space exploration has never been more present in the news, and the questions it raises (how do you stay in orbit? why do you float in space? how do you slow down to land on the Moon?) are at the heart of middle school and high school physics curricula. In this article, we propose seven experiments that can be performed w

You have probably already tried to disturb a compass by bringing a magnet close to it, but have you ever tried the same experiment with your smartphone's electronic compass? In the video below, we conducted the experiment, and the result is surprising: the smartphone's compass appears to be unaffected by the presence of a magnet. Why such behavior? As a scientist, can we trust the magnetometer data? And what are the implications for measuring magnetic fields with a smartphone

Discovered in 1842, the Doppler effect has established itself as an essential investigation tool in modern science. This article details five activities adapted to different learning levels, to be carried out in class, at home or outdoors, simply using a smartphone or tablet. We will also provide specific advice to optimize their implementation. These practical experiments offer a unique opportunity to grasp the concrete applications of the Doppler effect in our daily lives,

The accelerometer has become one of the most important sensors in our cell phones. In this article we find out in detail what it is used for and how it works. Contents What is the accelerometer used for in a smartphone? - The different ways of calculating acceleration - Operating principle of the accelerometer - Measurement of displacement - MEMS technology - Absolute acceleration and linear acceleration - Precision and calibration of a MEMS accelerometer What is the accelero

Galileo's pendulum, astronaut centrifuge, Boyle's law, waves on a lake: these are classic physics experiments that would be interesting to perform with real equipment such as a smartphone, but that sometimes cannot be carried out physically. That is why we created a simulation tool within FizziQ Web — not to replace experimentation in the physical world, which remains the only truly relevant approach for analysing the world around us, but to make experimentation easier when i

The history of educational science software is, first and foremost, a history of teachers. Since the 1990s, teachers have been the ones building the tools that still equip thousands of classrooms today, coding in their own time, on evenings and weekends, for no pay. Over time, universities and foundations extended this offering with Scratch, PhET, Phyphox, and others: free software, often open source, adapted to real classroom needs because it was built by people who work the

In February 2026, Elon Musk announced his intention to install data centers in orbit to run artificial intelligence. Very quickly, one argument dominated the comments: in space, cooling would be “free”, since it is very cold there. This widely shared claim is nevertheless false. It reveals a common confusion between temperature, heat, and heat transfer. Above all, it offers a valuable opportunity to develop critical thinking and to revisit simple but fundamental questions: wh

The Shepard Tone : an infinite rise… or almost You're surely familiar with the Penrose staircase illusion, the seemingly endless staircase popularized by the artist M.C. Escher. But are you familiar with the Shepard Tone, an acoustic illusion conceived in the 1960s by the American psychologist Roger Shepard, which creates the impression that a sound rises—or falls—without ever reaching a peak? Let's explore and analyze this astonishing sound effect with the FizziQ app. The Or

The greenhouse effect, at the origin of the phenomenon of global warming, is difficult to show by simple experiments. Many proposals are however available on the internet but few are really reproducible and many give poor physical representations of the phenomenon [1] . This article offers practical methods and accessible tools to help teachers and educators explain this phenomenon in an engaging way. A popular greenhouse effect experiment - The challenges of the greenhouse
