Household water treatment and safe storage in emergencies

Web resource:
Short, illustrated instructions from the International Federation of the Red Cross and Red Crescent Societies on how to prepare drinking water in the home using simple methods (disinfection, sedimentation and filtration).


The brochure first of all provides information about the criteria for testing the water quality. It stresses the importance of drinking water treatment and of storing water hygienically and then describes the individual treatment methods. These are written largely in the form of pictograms so that the treatment methods are also understandable for the illiterate.

Information and ideas:
Some of the drinking water treatment methods shown here provide suggestions for freehand experiments.

Schallabstrahlung am Lautsprecher

Video (00:11 Minuten): Offenbar überträgt die sichtbar schwingende Lautsprechermembran ihre Bewegung als Schallwellen auf die Luft.Das Prinzip der Schallerzeugung und der Ausbreitung als Schallwelle in der Luft erkennt man sehr gut am Beispiel der Membran eines Lautsprechers. Übrigens, man sieht nur die tiefsten Töne. Bei den mittleren und hohen Tönen sind die Membranbewegungen so schnell, dass sie unsichtbar sind. Hinweise und Ideen:Zur Vorführung geeignet, aber auch zum Selbststudium der Schüler.Idee: Video erst ohne Ton abspielen und die Schüler sollen raten, was das für ein Geräusch/Ton sein könnte.Unterrichtsbezug:Akustische PhänomeneSchall/Akustik: KenngrößenKommunikation und VerständigungSchwingungen und Wellen

Sound synthesis from Double Muffled Dolphin

Web resource:This music automat in the form of an applet enables everyone to produce individual ambient sounds.The automat is playing an array of sound (like a looping tape). The array is updated with data from the various modules whenever new data is available. To reflect changes on potmeters and buttons the sound is constantly recalculated. The newly calculated sound is then copied to the sound array. To prevent clicks-pops and odd things to happen "recording" (copying) is synchronized with the "play-head's" position on the "tape".Tips for running the Applet: 1. Make sure that Java Runtime is installed and that the browser security setting permits the playing of JAVA Applets. 2. Greyed tabs mean that these have to be opened and settings made. 3. It is best to start with "DrumSynth" and click on "Activate" in "Module Control".Information and ideas:This tool involves more than just playing. It makes it possible to look at the subjects of sound production and sound design in a serious and systematic way.Relevant for teaching:MusicSenses discover the environmentGames to practise using the sensesSound production and analysis
