Cochlea - an overview

Labeled graphic:
The cochlea with the location of the vestibule, the oval window and the round window. To help understand where the sound enters and exits the cochlea.

The cochlea consists of a coiled canal which appears in three compartments in the section. The part leading upwards is called the scala vestibuli and begins at the oval window.

Between scala vestibuli and scala tympani there is a membranous tube which is also filled with fluid. This is where the actual hearing organ, the Organ of Corti is located.

Information and ideas:
Can be used in a worksheet, for work together on the digital projector, or as an overhead transparency.

Global energy supply - future development

Chart:
The development of the global energy supply from 1990 to 2035 is shown.

Reliable figures are available through 2012; from that date forward, the International Energy Agency must rely on estimates. The represented figures refer to the more optimistic New Policies Scenario, which takes into account political announcements and plans of governments, for example, to reduce CO2 emissions, although they have not yet been implemented. The estimated energy consumption for 2035 is 12,001 mtoe.

Energy consumption of household appliances

Chart:
The chart shows the electric power consumption and, in some cases, the water consumption of certain household appliances. The average consumption figures of appliances from 2009 and 2015 are compared.

The chart shows a comparison of the electric power consumption of dishwashers, washing maschines, fridge-freezers, and tumble dryers. The values for 2015 are based on appliances with efficiency class A+++. It is clear that a savings potential of 15 to 40 percent still exists. For example, a 2015 washing machine uses 40 percent less electricity and 15 percent less water on average than a 2009 washing machine.

Information and ideas:
Apart from using state-of-the art technology, people can also save energy when washing dishes, washing and drying clothes, and cooking through energy-aware behavior. What options are there?
