A1 Proteins to improve gluten-free doughs

Minke van den Nieuwendijk
Halepaghen-Schule Buxtehude

In my project, I investigated the effects of various additives in gluten-free doughs. The additives I used were psyllium husk powder, whey protein and pea protein in various compositions, which I added to a base mix. The aim was for the gluten-free dough to be as similar as possible to a gluten-containing dough, as I have coeliac disease myself and am therefore not allowed to eat gluten.
In initial tests, I was able to demonstrate an improvement in the dough structure with the addition of whey protein and psyllium husk powder. On the other hand, pea protein as an additive damages the dough structure.

A2 Horror films, what makes them so scary?

Marie Hilling
Gymnasium Ulricianum Aurich

I came up with the idea for this project because the current discourse on the meaning of trigger warnings made me want to do some research myself.
My project is about whether a preceding warning (trigger warning) or the knowledge that the content could be perceived as disturbing has an influence on the intensity of the feeling of fear when watching.
To clarify this question, I showed several test subjects two film sequences, one with and one without a warning, and recorded their heart rates in order to measure possible differences in their reactions and thus establish a correlation.

A3 The ideal rice mortar

Lukas Meyer, Niclas Jan Menze and Philipp Meyer
Marion-Dönhoff-Gymnasium, Nienburg

We looked at whether mixing different types of processed rice into lime mortar has an effect on the resistance of the solid mortar.
To do this, we produced rice porridge, rice flour and rice water and added them to the mortar mixture. We also included combinations of the rice variants in our measurements. We used the new mixtures to dry mortar blocks that we could use for our stability measurements. We measured with a vice and a suitcase scale attached vertically to the lever.
At the same time, we exposed some mortar blocks to high heat (gas burner) and cold (freezer) before the measurement to detect any possible influence of extreme weather conditions.
In the future, we plan to find an optimized ratio of dissolved amylopectin in rice water (the only working variant) to mortar powder.

A4 Foodprint - Sustainable food made easy

We are programming a website that allows you to scan food and then see how sustainable it is in terms of social, ecological and economic sustainability. We are looking at what sustainability actually means and then want to use our programming skills to make sustainable food easier and more convenient for others.

A5 Pig or not pig? - That's the question here!

Tobias Reinert, Marlene Meyer and Fabian Stutzke
Gymnasium Sulingen

AI technology in pigsties for greater animal welfare and economic efficiency?
This could become a reality with individual recognition and treatment of pigs. We have therefore tried to train a neural network that can differentiate between pigs based on their facial features. However, there are still some seemingly trivial hurdles to overcome.
Starting with the mere positioning of the camera, to huge amounts of data that required us to think in new ways.
"Pig or not pig?" was the first question we had to ask the AI in order to get closer to our goal of individual pig recognition. In the end, the big goal is digitized pig fattening.

A6 SmartWheel

Lotte Luise Goldenstein and Finja Harms
Gymnasium Papenburg

We have noticed in everyday life that there can be a relief for people who are dependent on a wheelchair in their everyday lives, have little strength in their arms or cannot coordinate them well. How are these people supposed to brake their active wheelchair safely and lock the brake?
Our idea is for a gyro sensor to register when the wheelchair is stationary and apply the brakes via a motor.
Then all that is needed is a command to release the brakes and the person sitting in the wheelchair can continue their journey.

B1 The flour revolution - acorn flour as an alternative to cereal flour

Matthias Schuback
Halepaghen-Schule Buxtehude

Acorns fall from the trees every fall, but are not used. In contrast, cereals are planted on a large scale every year, and climate change is making it increasingly difficult to grow and harvest them. In years with poor harvests, acorns used to be used as a substitute for grain. So why shouldn't this also be possible today?
As a plant, the oak is a climatic tree and therefore suitable for coping with more extreme conditions. The acorns therefore only need to be harvested and processed into flour. However, this varies in complexity depending on the type of acorn. But once the flour has been produced, the question arises as to whether the quality of the result is comparable to a product made from cereal flour. For this purpose, I compared the key ingredients of the flour.

B2 Web building of the sector spider as an indicator of environmental changes

Aruna Dongowski and Mara-Talea Palt
Gymnasium Eversten Oldenburg

Building a spider's web is a process that requires a highly cognitive effort. The influence of psychoactive substances on spider web building was investigated as early as the mid-1950s. NASA also carried out experiments in 1995 that demonstrated how various substances influence spider web patterns.
These investigations formed the basis for the question of whether the altered web building of spiders can serve as an indicator of environmental changes.
We investigated the web-building behavior of the sector spider (Zygiella x-notata) under the influence of caffeine. In the course of the experiments, we developed a methodology to study the web-building behavior of spiders. This could be used as an indicator to determine possible changes in the environment.

B3 Effects of microplastics in the soil on the growth of young birch trees

Marla Isert, Xenia Stammer and Leo Friedrich
Marion-Dönhoff-Gymnasium, Nienburg

In our project, we are investigating the effects of microplastics in the soil on the growth of young birch trees.
To do this, we cultivated perennial birch trees for a period of one year and then used two different sizes of microplastic in two different concentrations. After six and twelve months, we examined whether microplastic particles were present in the tissue of the birch trees using cross-sections.
Our results so far show that microplastics with a size of 80 µm are not absorbed into the tissue.

B4 The comorbidity of type II diabetes mellitus and depressive disorders

Deborah Bimpong
Bismarckschule Hannover

Millions of people worldwide die as a result of diabetes and depression. One aspect of this problem is that patients are inadequately informed about their pharmacotherapy.
Against this background, a model has been developed that makes it possible to characterize mechanisms that contribute to the pathogenesis of hyperglycaemic effects in the human organism. The model was explicitly designed for the use of noradrenergic antidepressants. To validate the above hypothesis, a pancreatic cell line (INS-1E) from a rat-type insulinoma (Rattus norvegicus) was used, whose insulin secretion is comparable to that of human pancreatic β-cells. In addition, parameters that correlate with the manifestation of type II diabetes were analyzed in control and insulin-resistant subjects.
The aim of the research project is to obtain additional evidence for research into diabetic diseases.

B5 PFAS concentrations in the Trave and Baltic Seas

Jeppe Precht, Mustafa Kağan Birben and Mette Strohmeyer
Gymnasium Syke

Per- and polyfluorinated alkyl substances (PFAS) are a group of chemicals that are also known as perpetual chemicals due to their longevity. Initial research showed that PFAS receive little mention in the media. In view of the serious health risks posed by this group of substances, this is certainly a cause for concern. While measured values on the occurrence of PFAS in rivers and lakes are already available in some cases, information on PFAS concentrations in the German seas is difficult to find. We therefore decided to investigate how high the PFAS concentrations are in the transition region of the River Trave near Lübeck and in the Baltic Sea. We also clarified whether, and if so, to what extent, the concentration decreases with increasing distance from the mainland. To this end, we took several samples along the River Trave and in the Baltic Sea. We were able to detect PFAS in every sample.

B6 Optimized PHB production by microbial electrosynthesis of Synechococcus sp.

Julia Lenger
Mariengymnasium Papenburg

The project "Optimized PHB production by microbial electrosynthesis of Synechococcus sp." investigates the positive properties of bacteria for our climate and attempts to optimize them with technical applications.
The aim of the project is for bacteria to filter carbon dioxide from our atmosphere and thus synthesize new, sustainable raw materials. For this purpose, the CO2 fixation rate of the photosynthesis of the cyanobacterium Synechococcus sp. is artificially increased by external influence using microbial electrosynthesis. The bioplastic polymer polyhydroxybutyric acid (PHB) is obtained from carbon dioxide.
The polymer does not have to be extracted from the bacterium, but the PHB is secreted by the bacterium and can be filtered out of the Synechococcus culture medium. This not only binds CO2 in a sustainable raw material, but also shows a way to reduce the production costs of PHB.

B7 Effects of silver nanoparticles on freshwater algae

Amelie Entzian and Katharina Schmidt
Stiftung Landschulheim am Solling, Holzminden

Nowadays, silver nanoparticles are found in countless products and end up in our planet's waters as a result of environmental pollution. The effects of this are still largely unexplored.
In this thesis, the effects of spherical silver nanoparticles are investigated. Different compositions of Chlorella algae and silver nanoparticles are examined using absorption spectroscopy. Characteristic peaks can then be used to detect nanoparticles that are not visible to the naked eye.
In general, it can be seen that the metabolism of the chlorella algae used is restricted. Mixtures of chlorella and silver nanoparticles turn brownish at different concentrations. Suspensions mixed with nanoparticles turn brownish within a short time.

B8 Catalytic properties of the enzyme urease

Tristan Piel
Goethegymnasium Hildesheim

They may be invisible to the naked eye, but no one in the world could live without them: Enzymes
In my project, I researched biocatalysts in more detail using the example of the enzyme urease.
In the first part of the project, I qualitatively determined the catalysis activity of urease as well as the cleavage products carbon dioxide and ammonia after catalysis.
The second part of the project focused on the quantitative determination of two enzyme kinetic values: using a dilution series approach, I experimentally determined the maximum turnover rate (vmax) of the urease per minute in addition to the Michaelis-Menten constant (Km).
My aim was to use comparatively simple experimental setups to determine values that are as comparable as possible with the values known from the literature. I refined my methods to achieve more precise results.
For example, I determined color values using an app and constructed a photo box out of wood.

C1 Polyvinylamine - as an absorbent in the amine wash

Julian Alexander Grube, Fabian Lochte and Tyler Finley Reichmann
Bernhard-Riemann-Gymnasium Scharnebeck

In our project, we are looking at the plastic polyvinylamine (PVA) and using an aqueous solution of it to separate carbon dioxide from gas mixtures.
We are analyzing the absorption of carbon dioxide in an aqueous solution with PVA in order to use it as a detergent in amine scrubbing, as unlike other substances it is not harmful to the environment or health. During amine scrubbing, the carbon dioxide reacts chemically with a component of the PVA and is then later released elsewhere to be used or stored.

C2 The CAZ: Direct Air Capture made easy

Jarne Seibt and Arne Koenen
Ubbo-Emmius-Gymnasium, Leer

Direct Air Capture is all the rage at the moment. We were already researching it when it wasn't quite so popular and are now ready to present our prototype: The CAZ.
Our CO2 absorption(Z)elle is a 3D-printed system for binding and dissolving CO2 from the atmosphere. Starting with "proof of concept" trials and later with more precise measurements, after many trials we have developed a model that meets our requirements and made improvements along the way.
Our chemical of choice is monoethanolamine, or MEA for short. It enables us to bind CO2 at temperatures of around 35-40 degrees Celsius and dissolve it at around 85 degrees Celsius, making it ideal for us. In the future, it would be particularly interesting to synthesize methanol from our bound CO2, but unfortunately our technical resources are not yet sufficient for this.

C3 Breath gas analysis in medical diagnostics using the example of diabetes

Gesa Leandra Heins
Zukunftswerkstatt Buchholz e.V.

In this project, I am working on breath gas analysis using gas chromatography in medical diagnostics. The focus is on the connection between the disease diabetes and the acetone concentration in the breath.
I am working with the X-Pid device, a novel, fast gas chromatograph that performs an analysis within 30 seconds.
First, I want to investigate the relationship between the intake of glucose and the acetone concentration in the breath of healthy people. Then I would like to compare the measured acetone concentration in the breath of a group of healthy people with the measured acetone concentration in the breath of diabetics.
Based on this, I would like to determine whether it is possible to draw conclusions about metabolic diseases such as diabetes using this type of analysis.

C4 Solar power from the television

Marlon Hendrik Müller and Raphael Schneider
Leibnizschule Hannover

In this project, we are bringing together two modern technologies that we encounter more and more frequently in everyday life. These are LCD screens on the one hand and solar cells on the other. We are asking ourselves whether and how it is possible to produce functional solar cells from the individual parts of old LCD displays. We also look at how such solar cells can contribute to a more sustainable future with more renewable energy sources.
To get to the bottom of this question, a broken television will be dismantled down to its smallest individual parts in order to obtain the transparent, electrically conductive glass that is built into its display. We go into the many small and large challenges of this process. Later, we use the extracted glass to produce a series of experimental dye-sensitized solar cells. Here, too, we encounter a number of challenges that need to be overcome.

C5 Recycling lithium-ion batteries

Timo von Hacht, Eva Janssen and Jan Löffelbein
Gymnasium Sulingen

The use of lithium-ion batteries is becoming increasingly important in the context of electromobility and digitalization. The batteries contain valuable raw materials that are only available in limited quantities on earth.
As part of our project, we therefore developed a suitable process for recovering the metals from lithium-ion batteries with a high level of efficiency. The lithium-ion battery first had to be mechanically processed so that the metals could be dissolved from the electrode material using acid leaching. This was followed by processes for precipitating and separating the metal components. Overall, a high degree of efficiency was achieved in metal recovery in this way. The lithium ions could be separated as lithium carbonate and lithium phosphate.

C6 Sustainable calcium-sulphur battery: an environmentally friendly alternative for the future

Linda Weise
Missionsgymnasium St. Antonius, Bad Bentheim

My research work is concerned with the development of an environmentally friendly battery based on calcium and sulphur as an alternative to conventional batteries. Compared to conventional battery types, which are harmful to the environment due to the use of heavy metals, among other things, my battery offers significant advantages. It uses inexpensive, widely available and non-hazardous materials, has no negative environmental impact and has a high potential performance.
By optimizing the electrode mixtures, I was able to significantly improve the performance of the battery in the course of my research work. This progress is an important step towards more environmentally friendly energy storage solutions and could help to reduce the negative impact of conventional batteries.

Climate change, energy transition: No longer dreams of the future, but omnipresent. However, a redox flow battery, which stores energy chemically, could be the solution. In order to make the potential and concept of the technology accessible to the general public, we are developing a series product for schoolchildren using 3D printing.
Our goal: an easy-to-construct, visual experiment, accompanied by comprehensive, multilingual learning material. The product is based exclusively on chemicals suitable for pupils, but requires protective goggles and gloves. Our product teaches scientific work at a basic level as well as the basics of organics.

C8 Clean drinking water - silver nanoparticles as an indicator for heavy metal ions

Jantje Kolberg, Lea Zickenrott and Daliya-Daylin Tas
Evangelische IGS Wunstorf

Everyone needs clean drinking water. In developing and emerging countries in particular, however, drinking water is often contaminated with heavy metal ions.
These can lead to serious illnesses and even death. When we heard about this, we wanted to help. That's why we produced chemically modified silver nanoparticles. We used these as an indicator for heavy metal ions.
We hope that, based on our research, a cost-effective test for heavy metal ions in drinking water can be developed.

G1 Testing the possibility of observing the exoplanet HAT-P-16b with an 80 mm telescope

Based on observations of a Jugend forscht project from 2022 of the planet HAT-P-16 b with a 200 mm telescope, we used new data from the robotic observatory of the Angelaschule to test whether we can obtain equally accurate analysis data of the planetary transit with an even smaller telescope aperture of only 80 mm.
The observations should further demonstrate that planetary analysis is possible despite the small aperture and urban environment. With the help of data binning, the data will also be summarized in order to compensate for measurement errors and improve the quality of the transit model fit.

G2 Modeling the railroad network through demand-oriented network design

Tim Kiebert
Ernst-Moritz-Arndt-Gymnasium Osnabrück

Rail travel is considered too slow and never punctual. Yet it is actually an opportunity to move people and goods in an environmentally friendly way, shift the modal split in favor of rail and reduce CO2 emissions. But how can this goal be achieved in the short term?
With the help of geographical analyses, I analyzed traffic flows, which I used for my network design. By methodically varying various parameters, I was able to determine relevant network quality factors.
I then combined these in my newly developed model for structuring rail networks and was able to determine that this can achieve significantly better connections on short and medium distances. In order to validate my network in practice, I implemented it on real routes, taking into account many technical railroad parameters, and validated it algorithmically in detail - this also showed the high potential of my network.

Soil improvement in private households - How to improve your own beds.
For people who don't want to use store-bought potting soil or fertilizer when planting their garden, there must be a suitable alternative, right? I am trying to find out whether it works just as well with simple things that are available or easy to obtain in the average household.
I have tested soil samples from the park near the school for their values, and then treated them with liquids such as herbal tea made from weeds, or mixed in small amounts of other nutrient-rich substances such as plant ash. I then tested these soil samples again for the density of nutrient salts such as phosphates and nitrates, and for short-term water holding capacity, to find out how these values change in the short and long term.

G4 Auroras and sunspots - how can we observe them?

Hoffmann-von-Fallersleben-Schule, Braunschweig

In our project, we want to learn about auroras. In 2023, auroras could also be seen over northern Germany. We would now also like to see if we can observe them.
We also want to investigate auroras and the sun in this context and see what they have in common. We found out that both have to do with the Earth's magnetic field.
We want to observe the sunspots with a telescope and take photos of them.
In the end, we found out that we could take the best photos with a self-made camera from a Raspberry Pi with a self-made adapter from the 3D printer. We also learned that there is a connection between the Earth's magnetic field and the Sun's coronal mass ejections. We therefore also built a magnetometer with which we wanted to try to measure changes in the Earth's magnetic field. Unfortunately, we have not yet been able to see auroras directly.

M1 Using field-programmable gate arrays to emulate quantum circuits

Jonas Müller
Vincent-Lübeck-Gymnasium, Stade

Functioning quantum computers with a large number of qubits could revolutionize problem solving in the future. This applies in particular to the fields of materials science, chemistry and climate research.
At present, conventional computers that simulate quantum computers are mainly used to develop quantum algorithms. As this is very computationally intensive, my project is investigating the possibility of simulating quantum circuits with so-called field-programmable gate arrays (FPGAs). FPGAs are circuits that can be programmed at logic level using hardware description languages. This allows the hardware to be perfectly adapted to a specific problem. With the help of my own processor architecture, including instruction set and optimized computing units, which I implement on my FPGA board, I am able to simulate quantum algorithms efficiently and quickly.

M2 Analysis of the optimization methods of mechanical neural networks

Alexander Reimer and Matteo Friedrich
Gymnasium Eversten Oldenburg

We have been working on the new, comparatively little-researched field of mechanical neural networks, or MNNs for short.
MNNs are programmable materials that can learn different behaviors. They consist of mass points that are connected to each other by springs - the behavior is determined by the stiffness of the springs. By adjusting the springs, it is possible to train different behaviors when external forces are applied.
While previous research has focused on the technical implementation of these networks, we want to analyze and optimize the training process.
To this end, we have already implemented the simulation of an MNN, implemented optimization algorithms ourselves and tested them with various parameters.
Our results should provide a good starting point for real MNNs. They show that MNNs can learn several complex behaviors.

There are 1.6 billion hearing-impaired or deaf people worldwide. I visited a deaf person at a school for the deaf. She told me about her everyday challenges. An interpreter could be a help for her, but in Germany there are around 100 deaf people for every interpreter. If you do manage to get one, however, it costs a lot of money.
ReadMyVoice offers a simple, inexpensive alternative.
The aim of ReadMyVoice is to use artificial intelligence to translate sign language into text. This is intended to significantly simplify communication with deaf people.
ReadMyVoice is an app that is mainly programmed in the Python programming language. Using data sets of sign language signs, the AI is supposed to learn simple numbers through to complete sentences.

M5 Veilo - a quantum-safe and modern chat app

Elias Kuscholke

The aim of my chat application is to be able to send quantum-safe messages that cannot be cracked by qubits in the future. This is necessary because quantum computers will become increasingly powerful in the coming years and could decrypt classic encryption algorithms such as RSA, which are often used today. I developed improvements for my app from the previous year using self-programmed quantum-safe algorithms, which I researched and programmed into my code as an interface. During development, it was particularly important to me to have a user-friendly design with intuitive operation of an elegant interface.
In addition to the functioning app, I also tried to gain a deeper mathematical understanding of NTRU and created a model algorithm on a multidimensional Bernoulli tree. Finally, my app has the future goal of combining chat apps on one platform.

Diabetes is not always easy to understand. You can behave in exactly the same way over several days, but your blood sugar will always react differently. This can depend on various factors, which are not always obvious. In order to better understand these processes, I have developed software using the Python programming language that automatically downloads and evaluates blood glucose data via the Internet. The data is processed graphically and can be shared with a doctor, for example, or used for personal analysis. Similar tools already exist, but they are either too confusing or work very slowly, which can make them a challenge to use. This is exactly what I wanted to improve.
With different chart views and a history of insulin deliveries and blood glucose levels, you can get an overview and adjust your therapy if necessary, giving you more freedom through better management.

P2 Coherence - waves in step

Nele Drüner
Johannes-Althusius-Gymnasium Emden
Development location: Emden/Leer University of Applied Sciences

In my last research projects, I always used light from different sources for different effects and measurement methods. Depending on the application, one or other light parameter (power, wavelength, beam quality) is important for the experiments. The property of coherence, which is especially necessary for interferometry, poses the following questions for many people: What does this property describe, how can it be explained and how can the quality of coherence be determined?
The coherence length characterizing this light property was measured for various laser types using an interferometer developed in this project. To determine the coherence length, investigations were carried out on intensity ratios, beam profiles and contrast in the interference patterns with different laser types. The properties of some optical assemblies were also included in the experiments to optimize the measurement procedure.

P3 Construction of a fiber-coupled spectrograph with variable resolution

Florian Waschki and Titus Schwegmann
Angelaschule Osnabrück

The branch of astronomy has been established at the Angelaschule Osnabrück in recent years, partly through the construction of two observatories.
Until now, measurements were based on photometric investigations. In order to achieve more precise observations, a spectrograph was to be purchased which, in addition to the intensity of the light, can now also display the various components of the light spectrum.
As a spectrograph attached to the telescope could impair the mechanical stability of the telescope and the resulting images, the wish was to build a spectrograph decoupled from the telescope and feed it via a fiber. In addition, the resolution can be adjusted on the computer using two reflection gratings. We present the planning and construction of the spectrograph as well as the first recordings of spectra.
Connection to the telescope and initial astronomical investigations using the spectrograph are planned for the near future.

P4 Measurement and evaluation of photovoltaic systems

Johannes Budemann, Carl Töllner and Nina Matthiesen
Hoffmann-von-Fallersleben-Schule, Braunschweig

In our project, we set up a small photovoltaic system and recorded the output using an Arduino.
To do this, we first had to reduce the measurement voltage to below 5 volts using a voltage divider. We also used a current sensor to convert the current into a value that the Arduino could read. After collecting the data, we filtered it, calculated meaningful time values from the runtime and displayed the data graphically.
This allowed us to draw conclusions about the performance of our solar cell under real conditions.

P5 Simulation and measurement of the trajectory of a water rocket

Jannis Ferber
Gymnasium Corvinianum Northeim

The aim of this project is to simulate the trajectory of a water rocket, which is to be tested using a self-built rocket. The main result is the general acceleration of the rocket based on the launch parameters. From this, the height and speed are calculated using Python. The practical verification, which is still inadequate due to technical problems, shows that the calculated height cannot be achieved in the idealized system, meaning that various simplifications regarding resistances have a measurable influence.
Further steps are the refinement of the calculation with resistances, as well as the reliable measurement of the actual flight path.

Machines are now way ahead of us in many areas. For example, they are faster and more precise. In our work, we have therefore looked at a way of transferring these properties to humans.
This involves the use of electrical muscle stimulation (EMS). First of all, the applicability of EMS for transferring the machine's advantages to humans was investigated in a model test. In order to demonstrate the practical applicability, a human hand was made to play a piano piece automatically based on these findings. In addition to improving the temporal precision of healthy people, this application could also enable paralyzed people to carry out their hobby.
