The Ear, Hearing and Hearing Impairment: European Commission - environment

Website:
Website where the topic of "noise avoidance and reduction - protect the environment" is dealt with.

Internet address which can be used as starting point for inquiry into legal aspects.

Information and ideas:
Good basis for independent inquiry and to find material for class papers.

The various types of soaps

Information module:
Useful information on the five most common types of soap: Curd soap, soft soap, fine and toilet soap, moisturizing and clinical soap, and shaving soap.

Soaps are the alkali salts of fatty acids.
The information module provides the definition of the five most common types of soap and an overview of their composition, raw materials, production, possible uses, and advantages and disadvantages.

Information and ideas:
The students can also make their own soap. Instructions can be found on numerous sites on the Internet.

; Physics and chemistry of water: The principle of evaporation

Simulation:
The principle of evaporation is presented in steps. Evaporation is one element of the water cycle, and also of the water-energy cycle.

The sun heats the water, which rises as invisible water vapour. The warm air cools in upper layers of the air and the vapour condenses.
This uses up energy (evaporation), which is then released again during condensation.

Information and ideas:
The principle of evaporation is one element of the water cycle.
Question: Why is the climate mostly milder in high-precipitation areas than in comparable dry areas?

Saponification and digestion of fat

Interactive chemical equations:
The chemical equations for the alkaline saponification of fat and the breakdown of fat in human digestion can be developed interactively.

Word and reaction equations are shown for the alkaline saponification of fat; only the word equation is shown for the breakdown of fat in human digestion.
The equations can be developed in two ways:
· Entire equation at once
· Individually by educts and products.

pH-values in the body and in everyday products

Interactive graphic:
A pH scale can be labeled interactively with typical sample values from the areas of "human body" and "everyday products".

The pH scale covers the entire range from 0 to 14 and shows that negative pH values are also possible.

The scale can be labeled individually or as a whole.

Phase diagram of water

Interactive diagram labeling:
A p-T diagram for pure water. The lines indicate the temperature and the pressure at which the solid, liquid, and vapor phases exist in equilibrium. All three phases exist in equilibrium only at the triple point; otherwise, there are a maximum of two phases.

The diagram can be labeled interactively, either individually or in full. Manual labeling on the interactive whiteboard is also possible.

Internal structure of a magnet

Simulation:
Ferromagnetic materials are made from many small elementary magnets and can be magnetized and demagnetized.


A collection of three independent simulations illustrates the essential properties of ferromagnetic materials. The physical principles are each summarized in a mnemonic that can be displayed and hidden. The simulations in detail:
· A magnet is disassembled. The inner structure made of elementary magnets (Weiss domains) becomes clear.
· The elementary magnets in a ferromagnetic material are aligned in an external magnetic field. The material becomes magnetized, and becomes a magnet itself.
· A magnetized material is exposed to heat or mechanical force and thus loses its magnetization. It becomes demagnetized.

Information and ideas:
The students can verify the illustrated facts in simple experiments.
