Principal Björn Gemmer recently presented certificates to students in the WU Computer Science program. They had participated in the Youth Computer Science Competition for eighth- and ninth-graders. Daniel Carle from class 8c even made it to the third round of the competition. Special congratulations to him! The other students received a certificate of recognition or an award for their participation in the second round. Posing for the photographer (from left) were Parsa Vahhabzadeh, Emil Graf, Dominik Koerth, Mika Koch, Maxim Kokaryev, Mio Bender, Daniel Carle, and subject teacher Nicole Scholtes. Jakob Tober is missing from the photo.
The students prepared for the competition as part of the WU Computer Science course and with the help of the learning platform, reports Nicole Scholtes. On the competition platform http://jwinf.de offers numerous practice problems at various difficulty levels, as well as past competition problems.

The Youth Computer Science Competition is a computer science competition for students with little or no programming experience. In the first and second rounds, participants can complete the tasks online. In the third round, they must complete more challenging tasks at home. The competition is open to all students in grades 5 through 13.

The first round began in February, and the students worked on the second round in class right after the Easter break. The third round, for which Daniel Carle has qualified, begins in September. “Students who are interested are welcome to contact me if they’d like to participate next year,” encourages Nicole Scholtes. To participate, you need a teacher account. More information can be found on the website https://bwinf.de/jugendwettbewerb/.

We have reason to celebrate! The Steinmühle has won the Hopp Foundation’s school award—worth €2,500—for its commitment to STEM education as part of the “Jugend forscht” state competition.

The Hopp Foundation is committed to promoting young talent in STEM subjects and has been a key supporter of “Jugend Forscht” for many years. Since last year, the award has honored schools that are particularly committed to fostering talented students interested in science and technology, thereby making an important contribution to strengthening science and technology in Germany.
This generously endowed award is—in addition to being a recognition of achievement—of course also a welcome opportunity to significantly expand Steinmühle’s science equipment.
A prerequisite for participating in the competition was a detailed application letter in which a project by Steinmühle plus STEM students played a significant role.

Plus-MINT Project in cooperation with Philipps University of Marburg

In collaboration with the University of Marburg, a project idea was developed to study the Lahn River in the area of the restoration site at the Gisselberg Span. Dr. Christoph Reudenbach from the Department of Geoinformatics is actively supporting the plus-MINT students with his expertise. The idea is to develop an autonomous, sensor-equipped boat to minimize the need to enter the sensitive ecosystem in the Gisselberg span renaturation area. This platform is designed to semi-automatically measure water quality in the Lahn River and collect water samples.
The project is a great opportunity for the students to learn how to build complex devices and program them independently for research purposes, as well as to deepen their knowledge in the fields of robotics, programming, and environmental sciences.

 

Strong Commitment to Environmental Education

In recent years, students at Steinmühle have submitted numerous projects to “Jugend forscht” and have often achieved great success. This year, they won two second-place finishes and one first-place finish at the regional competitions; one project even won the state award for the best interdisciplinary project in Hesse.
In his laudatory speech, Mr. Oliver Karplak, the state competition director for “Jugend forscht,” specifically highlighted Steinmühle’s strong commitment to environmental education and environmental projects in recent years. This helps raise students’ awareness of environmental issues and encourages them to act in an environmentally conscious manner.

 

A big thank you

Steinmühle is very proud that its work in the STEM fields has been recognized with this award, and we would like to once again extend our heartfelt thanks to everyone involved. The Hopp Prize is a wonderful recognition of this work and an incentive for the future to continue raising our students’ awareness of the importance of STEM subjects and environmental issues, and to offer them opportunities to actively engage in building a sustainable future.

A great success for our very young researchers from 6th grade: By winning the regional competition in Gießen, they qualified for the state competition and were able to travel to Kassel for two days with their advisor, Dr. Jutta Töhl-Borsdorf, to present their research project there. And they won there, too.
, Anna-Lena Griesler (11), Maya Fischer (11), and Marlene Wagner (12) focused on making adhesives from natural sources (as we reported), and this involved a lot of chemistry. But since the three didn’t stop at just making the adhesives—they also built a device to test their tensile strength—engineering played a major role in this project as well. Their force measurements using digital force sensors ultimately fell within the realm of physics as well.
This multifaceted approach—that is, its interdisciplinary nature—impressed the jury. The continuous refinement of the experimental apparatus and the depth of understanding with which they analyzed the underlying processes impressed the judges. In addition, they were praised for their confidence during the presentation and, in particular, for their strong team spirit.

The depth of content is something that is also close to the heart of “Jugend forscht” advisor Dr. Jutta Töhl-Borsdorf. “The three of them had to explain the different adhesive properties of the various materials on the paper. Since paper is made of cellulose, that’s more of a topic from 12th-grade chemistry class. Natural adhesives are also rather complex molecules. But you can ‘break it down’ into simpler terms.” During the jury deliberations, the team was able to impress with their expertise and technical terms such as hydrophilic and hydrophobic, hydrogen bonding, and cohesion and adhesion failures.

It was also great to see the students interacting with students from other schools. One team, for example, had been working on an adhesive made from mistletoe berries. A sample was quickly provided and measured by the girls. However, this adhesive turned out not to be suitable for everyday use just yet.
The team’s best adhesive consists of starch, sugar, and a little vinegar, which breaks down the starch molecules into shorter chains.
Last but not least, the Steinmühlen team also took home the special “Materials and Substances” prize from the Institute of Materials Science at the University of Kassel. In total, this meant prize money of 300 € for the three young researchers, though Anna-Lena noted: “The money isn’t really important at all. Spending those two days with like-minded people was the best part.”

We are very proud of you. Congratulations!

This year, our “Jugend Forscht” teams had to compete at two different locations.

What is the condition of the soil in our area?
Sisters Anna Dinges (12th grade) and Teresa Dinges (9th grade) traveled to Kassel on Saturday, February 11, with their project “Humus: Savior of the Soil and Climate?” on Saturday, February 11, along with their advisors Antje Seel and Dr. Jutta Töhl-Borsdorf. The North Hesse regional competition was held at SMA in Kassel-Niestetal.

Soils play a major role in the climate system because humus is capable_{of storing} large amounts of_CO2 . Anna and Teresa wondered about the condition of the soils in the areas where they live and go to school. In addition to measuring humus content, pH, and KAK values (a measure of soil fertility), they also investigated how soils react to acid rain. They compared the measurements from the soil samples they collected with those from commercially available potting soils and found that the latter actually had higher humus and KAK values. However, a coniferous forest soil also performed impressively overall. The jury particularly praised the outstanding laboratory work, which was conducted at a high level and with great precision, the rigorous scientific approach, and the in-depth examination of sustainability issues at the local level.

With their project, they won second place in the “Geosciences and Spatial Sciences” category and a special prize consisting of a one-year subscription to the science magazine “natur.”

Rainwater and Natural Adhesives
OnFriday, February 24, a large group set out for the University of Giessen to present their projects at the competition in Central Hesse. Anna-Lena Griesler, Maya Fischer, Marlene Wagner, Nico Farwig, Justus Pöschl, and Robin Richter—all from the 6th-grade GuFi lab groups—took on the challenge in the “Students Experiment” category.
The Steinmühlen bus was fully occupied with the six children, their supervisor Dr. Jutta Töhl-Borsdorf, STEM teacher Dr. Patrick Szabo, and participation assistant Steven Müller.
They set off at 7:45 a.m., and the morning was well filled with jury interviews and interesting lab tours. In the afternoon, the presentation booths were open to the general public. Many parents, grandparents, and friends took the opportunity to have the young researchers explain their projects to them. By around 5:00 p.m., everyone was tired but full of new impressions as they returned to the Steinmühle.
This year’s awards ceremony took place online on Saturday afternoon. To mark the occasion, all the students gathered at the Steinmühle for pizza. And finally, there was something to celebrate.

The group of three boys who asked themselves, “Is rainwater valuable?” won over the jury, taking second place in the “Geosciences and Spatial Sciences” category and a special prize of a one-year subscription to the magazine Geolino.
Justus, Nico, and Robin analyzed rainwater for various components, developed a water hardness test using soapy water, and found that cress grows better with rainwater than with tap water. The jury praised their clear methodology, the neat presentation of the measurement results, the visualization of the cress growth, and their broad knowledge.

Anna-Lena, Maya, and Marlene securedfirst place in the chemistry category—and with it, a spot in the state competition at the University of Kassel—with their project “How Tear-Resistant Are Natural Adhesives?” They made many adhesives themselves—for example, from food—and tested other natural substances, such as spruce resin, shellac, and snail slime, for their adhesive properties. The team also succeeded in developing a device to measure the adhesive strength of the substances on paper.
The jury was particularly impressed by how these very young students continuously refined and adapted their experimental setup. They paid close attention to accuracy and critically evaluated their approach in each phase of the experiment. Their strong problem-solving skills were evident.
The team also won the plusMint Special Prize for interdisciplinary projects.

If you’re interested in starting your own research project, just stop by the “Open Lab” at the Steinmühle—it’s open every Tuesday and Friday starting at 2 p.m. (Room 127).
