Distribution of land and water on Earth

Graphic:Percentage distribution of landmasses and oceans on Earth’s surface Oceans cover 70 percent of Earth’s entire surface. Landmasses thus amount to only 30 percent. When you see photos from space, it’s easy to understand why Earth is called the "Blue Planet.”Information and ideas:The students should discuss the proportions of the individual continents and oceans on Earth’s surface.

Sound emission at the loudspeaker

Video (00:11 minutes):The visibly vibrating diaphragm in the loudspeaker obviously transmits its movement onto the air as sound waves.The principle of sound production and propagation as sound wave in the air can be recognized clearly with the example of the diaphragm of a loudspeaker. By the way, only the lowest-pitched tones are visible. With medium and high-pitched tones the movements of the diaphragm are so fast that they are invisible. Information and ideas:Suitable for demonstration purposes but also good for self-study on the part of the students. Idea: show the film without sound to begin with. The students should then guess what sort of noise/sound it might be.Relevant for teaching:Acoustic phenomenaSound/acoustics: parametersCommunication and understandingVibrations and waves

Household water treatment and safe storage in emergencies

Webressource (en):
Eine kurze und bildliche Anleitung der Internationalen Föderation der Rotkreuz- und Rothalbmond-Gesellschaften, wie man im Haushalt mit einfachen Methoden (Desinfektion, Sedimentation und Filtration) Trinkwasser aufbereiten kann.

Die Broschüre klärt zunächst über Kriterien für die Prüfung der Wasserqualität auf. Die Bedeutung von Trinkwasserbehandlung und hygienischer Wasseraufbewahrung wird herausgestellt. Dann werden die einzelnen Aufbereitungsverfahren vorgestellt. Dies erfolgt größtenteils mit Piktogrammen, um auch Analphabeten die Aufbereitungsmethoden verständlich zu machen.

Hinweise und Methoden:
Einige der hier gezeigten Trinkwasseraufbereitungsmethoden liefern Anregungen für entsprechende Freihandexperimente.
