The 2017 \u201cJugend Forscht\u201d regional competition took place in February in Lollar at Bosch-Thermotechnik (formerly Buderus). For the first time, two groups from Steinm\u00fchle participated and immediately achieved very good results. The groups had to present their projects to a jury at an exhibition booth they had designed themselves.
\nThe girls won second place in the technology category, while the boys took second place in chemistry and the special prize for environmental technology (worth \u20ac50). <\/p>\n

Problems with the microfleece.<\/strong> A group of girls who are part of the \u201cWU Forschen\u201d program (grades 8\u20139) at Steinm\u00fchle under the guidance of Dr. T\u00f6hl-Borsdorf participated in the \u201cJugend forscht\u201d competition for teens aged 15 and older: Nelly Endres (8b), Lea Marko (8a), and Fl\u00fbte Seifart (9b). Their topic was: \u201cMicrofleece\u2014Does Superfleece Fail Even When Washed?\u201d <\/p>\n

\"\"<\/p>\n

The starting point was the observation that microfleece fabrics are very common in Germany. They\u2019re cozy, but unfortunately they get dirty pretty quickly. What can you do when these items aren\u2019t as soft and cozy after washing, and using fabric softener isn\u2019t always the solution? What works quite well for terry cloth towels is, unfortunately, only partially effective with microfleece.
\nTo verify that these weren\u2019t just subjective impressions, Nelly, Lea, and Fl\u00fbte built a device that can measure the \u201csoftness\u201d of a fleece fabric and provide other insights into what kinds of washing processes preserve the \u201csoftness\u201d of microfleece. The students also examined the fleece samples under a microscope and investigated how the texture of microfleece changes as a result of different washing processes.
\nIn the end, the students were able to report: <\/p>\n

\u201cIn this project, we succeeded in developing a machine and a method to measure the \u2018softness\u2019 of microfleece. Other findings include that microfleece should not be washed at very high temperatures, that the use of fabric softener is generally not recommended as it causes the fibers to \u2018stick together,\u2019 and that adding vinegar results in a very good softness rating.\u201d <\/em><\/p>\n

Expensive and cheap types of water<\/strong>. A group of students from Dr. T\u00f6hl\u2019s GuFi course took part in the \u201cSch\u00fcler experimentieren\u201d competition. This is the junior division of \u201cJugend forscht.\u201d The participants were sixth-graders Morten K\u00f6hler, Finn-Jonas Posingies, and Joshua Wieder. They were the youngest team in the competition. With their experiments, they wanted to find out:
\nIs premium water really better than discount store water? The students explained their research question: <\/p>\n

\u201cWhen we tested various tap water and river water samples for their components, we came up with the idea of analyzing mineral waters. We wondered whether the expensive premium mineral waters are really better or healthier than cheap discount store waters. To do this, we tested various water samples for different components (nitrate, nitrite, phosphate, etc.) that aren\u2019t listed on the label. Our goal was to determine whether it\u2019s worth spending so much money on mineral water. And here\u2019s what we found: Overall, it\u2019s fair to say that the price differences are only partially justified. Cheap mineral water can be good (tegut) or rather poor (Quellbrunn), but even expensive water sometimes has a higher nitrate content than discount store water, which isn\u2019t exactly ideal. However, we cannot make a definitive assessment because we were unable to test for other critical substances (e.g., heavy metals such as arsenic, radioactive uranium) or residues of pesticides or bacteria.\u201d<\/em><\/p>\n
