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.

Where will our electricity come from in 2050? (ES)

Chart:A bar chart shows global electric power generation by energy source (in 1,000 TWh). It is clear that fossil energy sources, especially coal, and the power plant technologies developed for them will continue to play a key role in the energy supply. However, this role will steadily shrink.Using the following source: World Energy Council, World Energy Scenarios - Composing energy futures to 2050, London, October 2013

The Ear, Hearing and Hearing Impairment: Structure and function of the middle ear

Worksheet:
Structure and function of the middle ear.

The worksheet contains a cross section of the middle ear to be labeled. Additionally the functions of the middle ear must be described.

Information and ideas:
Motivating target-orientated task of revising what has already been learnt. Students must have understood the structure of the ear in order to be able to explain the path of the sound waves.
It is conceivable that the worksheet can be done together in class with the help of an overhead projector.

Relevant for teaching:
The human body
Structure and functions of a sensory organ
Reception of stimuli and transmission of information

Development of renewable energies worldwide

Information module:The charts show that the development of renewable energies worldwide is progressing very rapidly. In 2005, the share of renewable energies worldwide was still approximately 12 percent. By 2014, the share had increased to approximately 19 percent, as the first chart shows. As the second chart shows, it will increase to approximately 30 percent by 2040 according to forecasts by the International Energy Agency (IEA). Many people view this skeptically, but the third chart shows that global investments in renewable energies has grown tremendously. In 2012 alone, for example, China invested US$65 billion and is now the global leader in renewable energies in absolute and relative terms. By contrast, the former front-runner, Germany, has fallen behind considerably. The fourth chart shows that the changeover to renewable energies in Germany is progressing rapidly when it comes to power generation, while it is stagnating for transportation and heating. This is a phenomenon that so far applies to most countries around the world.

Experiment

Siemens Stiftung

The Ear, Hearing and Hearing Impairment; Teaching unit: How I hear;: Experiments on bundling of sound

Experimentation instructions:
Experiment cards for students on bundling of sound, for example, megaphone or experiment with tube and funnel.

Instructions on how to conduct simple sound bundling experiments (ear trumpet, megaphone). In this way, the students learn about the phenomena through playing.
By the way: Sound can be bundled or funnelled. In the hearing process, this function is carried out by pinna and ear canal.

Information and ideas:
· Observe the safety information in the instructions as well as the applicable safety guidelines for your school and discuss it with your students.
· The experiments on the bundling of sound show the students that sound is often funnelled or bundled when it is transmitted or perceived.
· The experiments can be done either in groups or as station training.

Relevant for teaching:
Acoustic phenomena
Sound/acoustics: parameters
Vibrations and waves

The Ear, Hearing and Hearing Impairment;: Sound propagation experiments

Experimentation instructions:
Study of sound conductivity of different materials.

Sound can propagate in solid, liquid or gaseous bodies.
Glass, metal and wood, for example, are good conductors of sound.
Felt, cotton wool and polystyrene, for example, are bad conductors of sound.

Information and ideas:
To be done together with students in class or in group work.
