Sch=C3=BClersymposium in = Heidelberg

Rund 300 Teilnehmer besuchten das 6. = Sch=C3=BClersymposium der=20 Initiative Jugend und Wissenschaft in Heidelberg. Die Veranstaltung bot = den=20 angereisten Sch=C3=BClern und Sch=C3=BClerinnen mit ihren = Lehrkr=C3=A4ften neben drei=20 Fachvortr=C3=A4gen zum Thema Bionik wieder viel Raum und Zeit zur = Pr=C3=A4sentation=20 eigener Forschungsergebnisse in Naturwissenschaft und = Technik.

W=C3=A4hrend Dr. Knut Braun vom Internationalen = Bionik-Zentrum in=20 Saarbr=C3=BCcken eine umfangreiche allgemeine Einf=C3=BChrung in die = Bionik gab,=20 angefangen von Leonardo Da Vinci=C2=B4s Flugger=C3=A4ten bis hin zum = allseits bekannten=20 Klettverschluss, bot Dr. Olga Speck von der Universit=C3=A4t Freiburg = einen Einblick=20 in aktuelle Forschungsprojekte der Bionik. Die Freiburger Forscherin war = auch=20 ma=C3=9Fgeblich an der Entwicklung eines Bionik-Koffers f=C3=BCr den = schulischen=20 Unterricht beteiligt. Hier k=C3=B6nnen Lehrkr=C3=A4fte anhand von sechs = verschiedenen=20 Experimenten Zusammenh=C3=A4nge aus Naturwissenschaft und Technik den = Sch=C3=BClern=20 begreifbar machen.

Einsatz von Enyzmen sinnvoll

Meron Yemane und Verena Fath vom Geschwister = Scholl=20 Gymnasium in Mannheim vor ihrem Poster. (=C2=A9 = G=C3=B6ttert/BIOPRO)

Die ganze Bandbreite an Sch=C3=BClerinteressen im = naturwissenschaftlichen Forschen=20 zeigte sich auf dem =E2=80=9EMarktplatz der Ideen=E2=80=9C. So wollten = zwei Sch=C3=BClerinnen des=20 Geschwister Scholl Gymnasiums in Mannheim beispielsweise wissen, ob die = Enzyme=20 in den modernen Geschirrsp=C3=BClmitteln auch wirklich einen Nutzen = haben oder nur=20 einen Werbegag darstellen. Sie besorgten sich die Enzyme Protease und = Amylase=20 und f=C3=BChrten genaue Testreihen mit standardisiertem verschmutztem = Geschirr durch.=20 Ihr Fazit: Die Enzyme sind tats=C3=A4chlich von gro=C3=9Fem Nutzen. Die = Sp=C3=BClmaschinen=20 k=C3=B6nnen bei niedrigeren Temperaturen als fr=C3=BCher =C3=BCblich = eingesetzt werden. Statt=20 65=C2=B0C gen=C3=BCgen mittlerweile Waschtemperaturen von 50=C2=B0C, um = das Geschirr zu=20 reinigen. Die Empfehlung von Meron Yemane und Verena Fath lautete = deshalb: =E2=80=9EWir=20 empfehlen der Sp=C3=BClmaschinenindustrie die Enzyme f=C3=BCr die = Sp=C3=BClmittel der Zukunft=20 einzusetzen.=E2=80=9C

Handwerk gepaart mit Technik

Dennis Veit, Fabian Przybilla und Chris Hiatt = vom=20 Peter-Petersen-Gymnasium in Mannheim vor ihrem selbst gebauten=20 Hexapoden. (=C2=A9 G=C3=B6ttert/BIOPRO)

Ebenfalls viel Verst=C3=A4ndnis f=C3=BCr Technik gepaart mit = Spa=C3=9F am handwerklichen=20 Arbeiten zeigten drei Sch=C3=BCler des Peter-Petersen-Gymnasiums in = Mannheim. Sie=20 konstruierten im Rahmen eines Jugend-forscht-Projekts einen = w=C3=A4rmesuchenden=20 Hexapoden. Dieser kleine Roboter sucht selbst=C3=A4ndig mittels = W=C3=A4rmesensoren die=20 w=C3=A4rmste Quelle in einem Raum und kann somit helfen, erste = Brandherde schnell zu=20 erkennen und Alarm zu schlagen. Mit dieser Entwicklung landeten Chris = Hiatt,=20 Fabian Przybilla und Dennis Veit im Kreisfinale auf dem zweiten=20 Platz.

In 10 Stunden zur Simulation eines = Termitenh=C3=BCgels. Von=20 links nach rechts: Vincent Kertscher, Sebastian H=C3=A4mmer und Konradin = Krischke vom=20 Ottheinrich-Gymnasium in Wiesloch. (=C2=A9 = G=C3=B6ttert/BIOPRO)

Aber auch im neu eingef=C3=BChrten NWT-Unterricht an den Gymnasien = entstehen=20 interessante Arbeiten. So bauten Vincent Kertscher, Sebastian = H=C3=A4mmer und=20 Konradin Krischke in nur zehn Stunden im Auftrag ihres Lehrers vom=20 Ottheinrich-Gymnasium in Wiesloch einen k=C3=BCnstlichen = Termitenh=C3=BCgel. Sie=20 simulierten mit Teelichtern die W=C3=A4rmeeinstrahlung der Sonne und = konnten mit=20 Temperaturf=C3=BChlern nachweisen, dass die besondere Bauart und = Bel=C3=BCftung des=20 Termitenh=C3=BCgels zu einer deutlichen Temperatursenkung f=C3=BChrt. = Neben dem Anreiz=20 handwerklich aktiv zu werden, =E2=80=9Emachte es einfach auch = Spa=C3=9F=E2=80=9C, so Vincent=20 Kertscher =C3=BCber das NWT-Projekt.

Sch=C3=BClern der Informatik-AG des Heidelberger LifeScienceLab = gelang es mit=20 einfachsten Mitteln einen Low-Budget-3D-Scanner zu bauen, der = =C3=BCberaus=20 =C3=BCberzeugende Ergebnisse lieferte. Ein einfacher roter Linienlaser = f=C3=BCr 50 Euro=20 und eine Webcam f=C3=BCr 20 Euro aus dem Baumarkt dienten als=20 Ausgangsmaterial.

Zahl der Sch=C3=BClervortr=C3=A4ge = verdoppelt

Der Algenbioreaktor zur Kohlendioxid-Reduktion = von Patrick=20 Mours. (=C2=A9 G=C3=B6ttert/BIOPRO)

Hauptorganisator Dr. Fred Engelbrecht vom ExploHeidelberg hatte = dieses Mal=20 bewusst die Anzahl an Vortr=C3=A4gen der Sch=C3=BCler verdoppelt, damit = m=C3=B6glichst viele=20 ihre Arbeiten nicht nur in Form eines Posters, sondern auch in einem = Kurzvortrag=20 selbst vorstellen k=C3=B6nnen. So wurde ein zweiter H=C3=B6rsaal = eingesetzt, um parallel=20 zwei Vortragsreihen anbieten zu k=C3=B6nnen. Beeindruckend war dann auch = die=20 professionelle Pr=C3=A4sentation der jugendlichen Forscher. Der = dreizehnj=C3=A4hrige=20 Patrick Mours vom Moll-Gymnasium in Mannheim beispielsweise f=C3=BChrte = seine=20 Ergebnisse zu Forschungen an einem Algenbioreaktor zur Reduktion der=20 Kohlendioxidabgase von Autos vor. Letztendlich kam er zu dem Schluss, = dass =E2=80=9Edie=20 Idee, einen Algenreaktor unter realistischen Bedingungen einzusetzen, = verworfen=20 werden kann.=E2=80=9C Aber als Algenl=C3=A4rmschutzw=C3=A4nde entlang = von Stra=C3=9Fen oder auf=20 Verkehrinseln sieht er durchaus M=C3=B6glichkeiten, die Gr=C3=BCnalgen = zur=20 Kohlendioxidreduktion einzusetzen und somit dem Klimawandel entgegen zu=20 wirken.

Regionalsieger im Bereich Chemie bei = Jugend-forscht: Nele=20 Jensen und Imke Laukenau. (=C2=A9 G=C3=B6ttert/BIOPRO)

Zwei Sch=C3=BClerinnen des Carl-Benz-Gymnasiums aus Ladenburg = stellten Kosmetika=20 aus nat=C3=BCrlichen Stoffen her. Mit dieser Arbeit wurden Nele Jensen = und Imke=20 Laukenau Regionalsieger der Region Rhein-Neckar-Kreis im Fach Chemie = beim=20 Jugend-forscht-Wettbewerb. =E2=80=9EWir wollten das Produkt nicht = vermarkten oder so.=20 Aber wir haben damit etwas f=C3=BCr uns gemacht und etwas, was wir an = Freunde und=20 Verwandte verschenken k=C3=B6nnen=E2=80=9C, so Imke Laukenau in ihrem = zehnmin=C3=BCtigen=20 Kurzvortrag.
