<p>In the UK only 7% of students pursue a physics qualification at upper secondary level (16 – 18-year-olds), and only 0.7% study physics at university, and of those a disproportionate number come from the most economically affluent parts of society. Those from the least affluent parts of society are least likely to possess significant Science Capital, which not only impacts their participation in science but also their attitudes towards science. At the same time, it is known that whilst trust in science is generally high, there are significant elements of society who do not trust science and display science denialism in important areas including climate change. In this talk it will be suggested that improving Science Capital, the sum of a person’s science-related resources, through the use of Phyphox, may have an impact on developing engagement in science and building trust, necessary features for citizenship in modern society. An opportunity exists to harness the potential of Phyphox to engage a broader audience, through development of fun and relevant activities, making physics a familiar and integral part of lives.</p>

<p>Phyphox has opened new opportunities for experimental physics education. In this contribution, we present the redesign of the introductory undergraduate laboratory course at Sapienza Università di Roma, where phyphox has become the primary tool for data acquisition in many experiments. Rather than simply replacing traditional instruments, the adoption of phyphox enabled a broader pedagogical shift from following prescribed procedures to engaging students in authentic experimental inquiry.
We discuss the rationale behind the course redesign, the implementation of the open project, and the outcomes observed over several years. Students have demonstrated increased engagement and a deeper understanding of the experimental process. The experience suggests that phyphox is much more than a convenient measurement tool: it can become a powerful driver for rethinking the role of laboratory work in physics education.
</p><p>
As artificial intelligence progressively automates many aspects of data processing, the educational value of laboratory work increasingly lies not in performing repetitive technical operations but in asking meaningful questions, designing experiments, interpreting evidence, and critically evaluating results. By simplifying data acquisition and routine analysis, phyphox helps redirect students&#8217; effort toward these higher-level scientific practices.</p>

<p>Smartphones offer new opportunities for integrating experimental activities into university physics courses beyond traditional laboratory settings. In an introductory mechanics course, smartphone-based experimental tasks using phyphox and additional sensor modules were implemented as regular course assignments. The project examined how students perceived these activities, particularly with regard to feasibility, motivation, and perceived learning outcomes. This talk presents selected findings from the empirical investigation and discusses implications for the use of smartphone-based experiments in higher education. Particular attention will be given to the potential benefits, practical challenges, and possible directions for future course development.</p>

<p>Amusement parks let you experience the weightlessness of free fall in drop towers and over large roller coaster hills. Forces required for acceleration are felt thoughout your own body – and can be registered with a smartphone taken along. Integrating accelerometer data from a drop tower gives velocity, which can be compared to the derivative of elevation, as extracted from barometer data. What is the acceleration in a swing, what forces act, what does your body feel – and why? The largest accelerations in roller coasters are change of direction, highlighting the vector character of motion. Orientation and rotation matter when the body is you own. When all students have easy individual access to data collection with phyphox, teachers no longer have to be equipment centrers during amusement park visits, and can, instead, focus on discussions of the results and challenge incomplete understanding. Smartphone data collection with phyphox is a game changer for physics outside the classroom.</p>

<p>A smartphone is not the best tool available for performing physics measurements (you can easily find better light sensors, magnetometers or motion sensors…), but they do have many advantages, among them being very common among our students. Another important quality, which we tested extensively, is the fact that they allow to experiments to be taken out of the laboratory, into a regular classroom, at home, in a museum, or in a forest. I will present several classes that we developed and present the educational benefits of getting out of the lab.</p>

<p>Experiments illustrating quantum phenomena are often difficult to implement in education. Even experiments that use classical light to demonstrate key quantum concepts can require costly, alignment-sensitive, and technically demanding optical setups. We present a novel, modular photonics platform designed to lower these barriers through 3D-printed optomechanical components, low-cost sensors, and ESP32-based electronics. Using the phyphox Arduino library, measurement data are transmitted directly to students&rsquo; smartphones, where phyphox provides an accessible interface for real-time visualization, data analysis, and experiment control. The poster presents the educational rationale, outlines the hardware and software architecture, and illustrates the platform&rsquo;s application through selected experiments.</p>

<p>Phyphox is an extremely powerful and flexible measurement tool. Especially, because it allows to read out external sensors via Bluetooth. The goal of the Laborino project is to make use of this external sensor capability and provide users with a cheap option to realize their own measurement unit. This contribution introduces the main ideas and design guidelines of the Laborino project and its current status. Laborino is an open educational resource, i.e. everything is for free!</p>

<p>As part of a Bachelor’s thesis, experiments were developed and tested for the playground to help school pupils in (lower) secondary education, as well as interested amateurs (children or adults who have not studied physics since leaving school), to experience key mechanical concepts such as speed, acceleration and force. Using the phyphox app, everyday movements – such as swinging or spinning on a merry-go-round – can be transformed into quantifiable measurement processes, thereby establishing a close link between physical experience and the modelling of physical phenomena. Instructions for carrying out the experiments and tasks for evaluating and interpreting the measurement data were created with reference to research into pupils’ conceptual understanding. The experiments investigate the period, velocity and acceleration on a swing, and the centripetal acceleration on a merry-go-round. Initial feedback from 36 pupils indicates not only a high level of motivation and positive response, but also great potential for explaining physical phenomena clearly and supporting learning processes in the long term. The design of the experiments and the results of initial trials are presented in the poster.</p>

<p>This study is a STEM + Sport case study conducted with four 11th-grade students in Türkiye. The biomechanics of rowing strokes were examined using acceleration data collected via the Phyphox mobile app, analyzed through Python code generated with ChatGPT in Google Colab. Students tested carbon fibre, aluminium, and composite oars under both with-current and against-current flow conditions, calculating stroke period via autocorrelation analysis. Results showed carbon fibre oars produced the shortest stroke periods (3.0 s with current, 3.2 s against current) and highest average acceleration (~2.0 m/s²), while aluminium oars had the longest periods (3.17&ndash;3.35 s) and lowest acceleration. Students demonstrated conceptual progress, linking acceleration to force via Newton&#8217;s second law and connecting autocorrelation patterns to periodic motion. The study highlights how combining sport-based contexts, smartphone sensors, and AI-assisted coding can boost STEM engagement and identity.</p>

<p>Chemical kinetics is a fundamental topic studied in both secondary education and chemistry undergraduate courses. Basic concepts such as reaction rate, rate equation, and reaction order are introduced. To help students fully grasp these ideas, practical laboratory sessions are beneficial.  A common tool used for these experiments is the UV-VIS spectrometer, where the variations of sample absorbance are used to follow the time evolution of the chemical reaction. However, these devices may present some disadvantages that can restrict their educational use. As an alternative, a smartphone can be used to record a video of the chemical reaction, analysing afterwards with Tracker software the RGB channel intensities over time. In this poster, we present an experimental laboratory activity based on a smartphone low-cost modular DIY device, and applied in two case studies: the thermal bleaching of malachite green, and the photoisomerization of methyl blue.</p>

<p>The research approach aims to increase acceptance of smartphone experiments in physics lessons by distributing materials and offering teacher support for these experiments using the free phyphox app, which turns smartphones into mobile measuring instruments. The phyphox:kit includes worksheets, accompanying materials, and accessories for experiments across the core physics curriculum for students aged 10 to 16 as well as materials for a 90-minute introductory lesson. A study is evaluating the materials in the kit as they are used in school practice. Up to 23 schools are currently participating in the ongoing pilot study. The study also examines possible changes in teachers&#8217; attitudes towards the use of smartphone experiments in science lessons when they are supported with comprehensive materials for introducing the experiments.</p>

Students measured the acceleration of a tablet suspended from a vertical spring in real time and compared small and large amplitude oscillations. The graphs showed that acceleration changed periodically, that larger oscillations produced larger acceleration amplitudes, and that the period changed very little.

<p>In our first year course Mechanics and Relativity, students perform a gyroscope practical to study precession, which is measured with a TI SensorTag CC2650 wireless sensor communicating with phyphox. Nutation is often observed in the practical in addition to precession and the nutation period is easily derived from the precession measurement. Analysis of nutation (not discussed in the accompanying lectures) is optional for students and it may give them information about a topic they do not learn about otherwise. Precession and nutation measurements are presented and reports are investigated to check how many students recognize nutation in the lab and if they do, how they take it into account in their analysis.Student use of phyphox and wireless sensors in later project practicals will also be discussed. Some examples of using phyphox (and a wireless sensor) in a lecture demonstration and in experiments in more daily life, outside the physics lab, will be presented as well.</p>

<p>We present an 18-channel visible/NIR spectrophotometer (410-940 nm) for secondary schools. Built with a SparkFun Triad AS7265x sensor, an ESP32, and phyphox via Bluetooth Low Energy, the hardware costs under €100. A single firmware supports three phyphox experiments: Triad_Spectra, Triad_Ratio, and Triad_NDVI. Triad_Spectra displays full spectra using dark and white calibration. It yields transmittance and corrects sensor gain artifacts, supporting Beer-Lambert curves and chlorophyll photometry. Triad_Ratio computes any two-channel ratio, facilitating various applications such as olive-oil authentication and turbidity checks. Triad_NDVI computes (NIR-Red)/(NIR+Red) at leaf scale, the contrast satellites use for vegetation monitoring, requiring white-paper reference calibration. The software was developed iteratively with AI assistance (Claude, Anthropic), an approach we believe can substantially shorten the development cycle of such instructional instruments.</p>

<p>Unexpected faults in rotating machinery can cause equipment damage, downtime and increased maintenance costs. This project proposes a low-cost IoT-based condition monitoring system using a smartphone as a vibration sensor and the phyphox application for data acquisition and visualisation. Three-axis acceleration data from a rotary test rig will be collected through the phone&rsquo;s built-in accelerometer and analysed using time-domain and frequency-domain techniques. Features such as RMS, standard deviation, peak-to-peak value, crest factor, skewness, kurtosis, and rotational frequency components will be extracted. The system will be developed to identify normal operation, single imbalance, coupled imbalance and misalignment. Its performance will be evaluated in terms of classification accuracy, repeatability, response time and cost. The proposed system aims to provide an accessible solution for fault detection and predictive maintenance in rotating machinery.</p>

<p>What your body feels in swings, carousels or rollercoasters is related to the forces required to change motion. These forces can measured by a smartphone accelerometer. The embodied experiences depend on the equivalence between inertial and gravitational mass, which often leads to surprising consequences, that can deepen the understanding of Newton&#8217;s laws. A number of visual examples of experiments, demonstrations and analyses are presented that can challenge incomplete understanding.</p>

<p>phyphox provides outstanding flexibility by supporting external data acquisition via Bluetooth. To exploit this feature, we designed an extracurricular workshop for secondary school students (grades 9&ndash;13) who assemble custom sensor boxes using a guided approach. Participants acquire foundational skills in 3D printing, soldering, and coding by specifically modifying provided STL files and script templates. The finished boxes enable individual research projects as well as standard classroom activities. This contribution provides insights into the workshop&#8217;s practical schedule and outlines its underlying pedagogical concept. The technical engineering of the hardware is detailed in the companion presentation &#8220;External Sensors for Phyphox: The Laborino project&#8221;.</p>

										<content:encoded><![CDATA[
<p class="wp-block-paragraph">As part of the phyphox talk at the International Conference on Physics Education 2022 and in honor of IUPAP&#8217;s 100th anniversary, we determined Earth&#8217;s radius/circumference with phyphox.</p>



<p class="wp-block-paragraph">The following map shows the contributions from the conference and the possible distances of at least 1000km that were available for the calculation.</p>



<figure class="wp-block-image size-large"><img fetchpriority="high" decoding="async" width="1024" height="512" src="https://phyphox.org/wp-content/uploads/2022/12/result-1024x512.png" alt="" class="wp-image-3479" srcset="https://phyphox.org/wp-content/uploads/2022/12/result-1024x512.png 1024w, https://phyphox.org/wp-content/uploads/2022/12/result-300x150.png 300w, https://phyphox.org/wp-content/uploads/2022/12/result-768x384.png 768w, https://phyphox.org/wp-content/uploads/2022/12/result-1200x600.png 1200w, https://phyphox.org/wp-content/uploads/2022/12/result.png 1400w" sizes="(max-width: 709px) 85vw, (max-width: 909px) 67vw, (max-width: 1362px) 62vw, 840px" /></figure>



<p class="wp-block-paragraph">After filtering 50% outliers (iteratively removing the result that most deviates from the current mean) we got an Earth radius of 6015 km. (Actual average radius is 6.371 km.)</p>



<h2 class="wp-block-heading">Physics background</h2>



<p class="wp-block-paragraph">In order to determine Earth&#8217;s radius, the participants will submit the altitude and azimuth at which they see the sun at their locations. The altitude is determined from the inclination of the phone as measured with its accelerometer. The azimuth is measured by the magnetometer, acting as a compass.</p>



<p class="wp-block-paragraph">These measurements are to be taken at the same time, so that the position of the sun in combination with the distance between the locations of the participants can be used to calculate Earth&#8217;s radius &#8211; similar to the method used by Eratosthenes in about 240 BC.</p>



<p class="wp-block-paragraph">However, there are two critical details in the original experiment by Eratosthenes that are extremely simplified in our version: The distance between locations and the time. Originally Eratosthenes needed two places at a known distance to measure the length of a shadow at the same time. Since time measurement was nowhere nearly precise enough, he relied on two locations being on the same longitude and measuring at noon.</p>



<p class="wp-block-paragraph">In order to allow participants to contribute from any place during the conference, we instead coordinate the measurement with any modern clock and communication tools available. Furthermore, we simply derive the distances from GPS coordinates.</p>



<p class="wp-block-paragraph">So, considering that the knowledge of Earth&#8217;s radius is quite certainly a prerequisite to operate a global navigation satellite system, this aspect should be viewed as a demonstration of the principle and of the network interface of phyphox.</p>



<h2 class="wp-block-heading">Original instruction</h2>



<p class="wp-block-paragraph">Install phyphox on your phone and load the following experiment either by opening this page from your phone or scanning the QR-Code from the [+]-Menu in phyphox:</p>



<p class="has-large-font-size wp-block-paragraph"><a href="phyphox://phyphox.org/earth-radius/earth-radius.phyphox">Earth Radius Experiment</a></p>



<p class="wp-block-paragraph">On 6th December 2022 at 6:00 UTC / 17:00 AEDT / 14:00 WITA / 13:00 ICT (during the break after Streams A2/B2/C2 of the conference), open the experiment and press the triangular play button to start measuring. Point your phone at the sun. You can optimize the phone&#8217;s orientation by looking at its shadow and trying to minimize its size. Then press &#8220;submit&#8221; to contribute your location and the sun&#8217;s position from your point of view.</p>

										<content:encoded><![CDATA[<h2>Results</h2>
<p>This experiment has been conducted on the 22nd December 2019 (winter solstice). Here we present the results. The original description can be found further down.</p>
<p>Without further ado, here is the result of the experiment:<br />
<img decoding="async" src="https://phyphox.org/suntrace/result/fit.png"><br />
Black points represent the location of a user who has submitted a measurement. Red crosses represent the calculated location of the sun (average over one hour in five minute intervals, see below) and the blue line a fit to the sun&#8217;s path. As the sun was traced during the winter solstice, this corresponds to the axial tilt of Earth. The fit yielded 23°.</p>
<p>The red crosses are obtained for a reference time at five minute intervals. For each reference, the data points of the past hour are used to calculate the position of the sun. Then from these positions, 50% outliers are removed by iteratively calculating the average location, removing the measurement that is farthest away and then repeating this over until 50% remain.</p>
<p>Here is an animation of the submitted data over time:<br />
<video src="https://phyphox.org/suntrace/result/suntrace.mp4" autoplay="autoplay" loop="loop"></video><br />
(Black lines are great circles from the users position to the individually calculated sun positions. Note that the representation glitches when crossing the edge of the map.)</p>
<p>If you want to play with the original data set as contributed by the users, you can download it <a href="https://phyphox.org/suntrace/result/data_anon.csv">here</a>. This data set contains every submission by every user with all the original data with only minor changes to ensure the user&#8217;s anonymity:</p>
<ul>
<li>The user ID has been replaced by a simple unique number.</li>
<li>Latitude and longitude have been rounded to two decimals to mask the location while retaining enough precision for calculations.</li>
</ul>
<p>The columns are the timestamp of submission, a unique ID to match individual users, latitude, longitude, altitude, azimuth and magnetometer calibration. The magnetometer calibration is an estimate of the calibration quality by the phone&#8217;s operating system. Zero means that the magnetometer is not calibrated and three is the highest possible calibration quality.</p>
<h2>Original instructions</h2>
<p>[<a href=" https:=" "="" phyphox.org="" soleil"="">French</a>] [<a href="https://phyphox.org/sonne">German</a>] [<a href="https://phyphox.org/sol">Portuguese</a>] [<a href="https://phyphox.org/suntrace/phyphox-winter-solstice.pdf">Taiwan / Trad. Chinese</a>]</p>
<p><a target="_blank" href="https://phyphox.org/suntrace/img/map.png" rel="noopener noreferrer">Preview of the trace so far and the contributions from the past 15 minutes.</a></p>
<p>This is a collaborative experiment, which is planned for the 22nd December 2019 (winter solstice). We try to track the movement of the sun across the sky by users world-wide. <b>And you can help us!</b></p>
<p>Simply open <a href="phyphox://phyphox.org/suntrace/sun.phyphox">this experiment</a> in phyphox, point your phone at the sun at different times across the day (22nd December 2019) and submit its position to us.</p>
<p><img decoding="async" class="aligncenter size-full wp-image-2036" src="https://phyphox.org/wp-content/uploads/2019/12/sun_expl-1.png" alt="" width="1000" height="500" srcset="https://phyphox.org/wp-content/uploads/2019/12/sun_expl-1.png 1000w, https://phyphox.org/wp-content/uploads/2019/12/sun_expl-1-300x150.png 300w, https://phyphox.org/wp-content/uploads/2019/12/sun_expl-1-768x384.png 768w" sizes="(max-width: 709px) 85vw, (max-width: 909px) 67vw, (max-width: 1362px) 62vw, 840px" /></p>
<p>There is a simple way to ensure that your phone is aligned well. Just look at its shadow. If it is as small as possible, your phone is pointing directly at the sun.</p>
<p>After the event, the data will be usable by teachers in their courses and by students who want to analyze it. Of course, we will also make it available on this page.</p>

										<content:encoded><![CDATA[<p>Finally, after much more time than anticipated, the big update has been released: Version 1.1.0</p>
<p>This one includes interactive graphs (zooming, picking points, measuring differences between points), new graph types (multiple data sets, bar charts, color plots), experiment transfer via QR codes and an extremely versatile Bluetooth Low Energy interface.</p>
<p>We could write entire articles on each of these and there are so many more improvements and small details&#8230; Well, here is a video with a quick overview of the big ones.</p>

<p>If this is not yet enough for you, here is the full changelog:</p>
<h2>Changelog</h2>
<h3>Changes on Android and iOS</h3>
<ul>
<li> Phyphox is licenced under the GNU General Public Licence from this version onwards</li>
<li> Bluetooth Low Energy support</li>
<li> Bluetooth Experiments included: Generic heart rate sensor, generic HID mouse, PocketLab One, PocketLab Voyager, Sensirion Smart Humigadget, Texas Instruments SensorTag CC1350/CC2650</li>

<li> New experiment: Applause meter</li>
<li> Multi-line plots</li>
<li> Bar charts</li>
<li> Color plots (used in spectrum experiments)</li>
<li> Open experiments from zip files or QR codes</li>
<li> Raw sensor experiments now feature a multi-line version</li>
<li> New languages: Chinese (simplified script), French, Vietnamese</li>
<li> Acoustic stopwatch has a new &#8220;many&#8221; tab , which allows measuring of an unlimited number of events, giving each interval and calculating the rate (Hz or bpm) and average interval of all events</li>
<li> Improvements to make the sonar more reliable</li>
<li> Performance optimizations for several experiments</li>
<li> Distance from start info for GPS-Experiment</li>
<li> Inclination experiment now features several different reference systems</li>
<li> Removed the libraries jquery and flot from the remote interface, which now uses chart.js instead</li>
<li> Remote interface now starts with a font-size recommended by the browser and allows changing the font size</li>
<li> Picking data points in the remote interface</li>
<li> The remote interface allows to show a single graph filling the full screen</li>
<li> Remote interface now communicates through a queue to avoid missed requests by the single-threaded webserver on the phone</li>
<li> Introduced a default color palette, which is used for coloring multiple graphs and can be referenced to by using names (red, blue, etc.) instead of RGB-values</li>
<li> Experiment configurations can be loaded directly from BLE devices</li>
<li> New device info report from menu on main screen</li>
<li> Add color to special categories (saved states and simple custom experiments)</li>
<li> Allow external experiments to define icon and category colors</li>
<li> Allow renaming of saved states</li>
<li> Use experiment title as default file name when exporting data, saved states or screenshots</li>
<li> Show state title in experiment info</li>
<li> Add hint to start button and add logic to hint bubbles, so they only show up until the user has used the specific function a few times</li>
<li> Fix: Wrong scaling of data in Doppler experiment due to outlying points</li>
<li> Fix: Consider available precision in remote interface to avoid retrieving the same value multiple times</li>
<li> Improve magnetic ruler for longer measurements</li>
<li> Fix inelastic collision experiment only working after pressing &#8220;reset&#8221;</li>
<li> Disable export and explain it to the user if an experiment configuration does not define an export</li>
</ul>
<h3>Changes on Android</h3>
<ul>
<li> Fix calculation of GPS height above geoid (MSL) if non-GPS satellite systems (GLONASs) are used</li>
<li> Vertical accuracy in GPS data if supported by some Android 8+ devices</li>
<li> Support temperature and humidity sensors</li>
<li> Support vendor-specific sensors by guessing their function by name</li>
<li> Improved performance by using native code for some operations</li>
<li> Improved Fourier transform performance by using the FFTW library</li>
<li> Allow screen rotation during measurement (now consistent with iOS)</li>
<li> Prevent adding identical experiments multiple times</li>
<li> Add notice when no address for the remote access is available</li>
<li> GPS now also uses network data by default and offers to force GPS only in the menu</li>

<li> Fix: Sort categories case-insensitive</li>
<li> Fix loading experiments from URLs without query strings</li>
<li> Fix: Result response from webserver used broken JSON format.</li>
<li> Limit state title length</li>
</ul>
<h3>Changes on iOS</h3>
<ul>
<li> Complete rewrite of experiment parser. Much faster and much more stable when loading external experiments with errors.</li>
<li> Buffer rewritten. This should fix previous crashes in long-term measurements due to a race condition when accessing the buffers.</li>
<li> Respect save area guides to avoid drawing the UI in areas used by system buttons or the notch (iPhone X and similar)</li>
<li> Fix: Missing parts of a translation fall back to English defaults</li>
<li> Fix: Pick experiment language according to app language and avoid using unreleased languages already present in the experiment definition files</li>
<li> Fix: Re-saving states crashes the app</li>
<li> Fix: Power function fails for negative exponents</li>
