Proportion of water in various organisms

Animation:
Water is the original building block of all life on Earth. This is also shown by the relatively high water content in humans, animals and plants.

People are about 70% water - babies even 75%. Water is in every body cell, it forms the basis for our blood, for every type of tissue cell and for the entire human brain.

Information and ideas:
Students can first guess how much water there is in humans, animals and plants.
This interactive graphic can be the starting point for working on the topics "role of water in the body" and "water intake and loss in people".

Photosynthesis - principle

Simulation:
The simulation shows how a plant produces chemical energy in the form of oxygen and glucose from water, carbon dioxide, and light.


Photosynthesis is the energy conversion process in plants. In this process, the radiant energy of the sun is converted with water and carbon dioxide into chemical energy in the form of carbohydrates.

The Ear, Hearing and Hearing Impairment; ; Teaching unit: Personal health care for the ear: This is how I damage my sense of hearing

Interactive graphic (with audio):
What happens with my hearing or hearing ability if I listen to music which is too loud, for example, with earphones, or I listen to it for too long?

This example clearly shows that after two hours of listening to loud music, a person?s ability to hear is reduced significantly.

Information and ideas:
When it comes to drugs and alcohol, young people are often no longer receptive to good arguments. This is different when it comes to volume. Young people subject themselves to excessive volume usually without thinking about it. The result that can be tested on oneself that listening to loud music for just two hours leads to a clear deterioration in hearing does give them food for thought.

Relevant for teaching:
Noise: causes, effect, protection
Noise consumption and leisure-time activities
Senses discover the environment
Keeping the sense organs healthy

Fotosíntesis: principio

Simulación:
La simulación muestra cómo una planta produce energía química en forma de oxígeno y glucosa a partir de agua, dióxido de carbono y luz.


La fotosíntesis es el proceso de conversión de energía en las plantas. En este proceso, la energía radiante del sol se convierte, con agua y dióxido de carbono, en energía química en forma de carbohidratos.

Katalyse - Prinzip

Grafik, interaktiv:Der Einfluss eines Katalysators auf die Geschwindigkeit einer chemischen Reaktion wird gezeigt. Zum Vergleich werden können auch die Reaktionesgeschwindigkeiten ohne Katalysator bzw. bei Temperaturerhöhung betrachtet werden.Durch Klick auf den Button “Start” kann die Reaktion gestartet werden.Über die folgenden Buttons können die Reaktionsparameter verändert werden: • Bei Klick auf den Button “Temperatur” wird die Temperatur, bei der die Reaktion stattfindet, von 25 °C auf 600 °C erhöht.• Bei Klick auf den Button “Katalysator” wird ein Katalysator zugegeben.Durch Klick auf den Button “Reset” wird der Anfangszustand (25 °C, kein Katalysator, keine Reaktion) wieder hergestellt.

Sound transduction physiological vs. electronic

Animation:
Shows that ear and microphone function in a similar way.

Sound transduction in the ear is based on the same principle as in a microphone: It codes the information.
In the ear the sound waves are converted into electrical impulses in the brain.
In a microphone the signal is also converted into electric currents.

Information and ideas:
The animation makes it clear that technical devices are often based on natural "models". Students can be asked to think of other examples of technology imitating nature.

Relevant for teaching:
Vibrations and waves
Structure and functions of a sensory organ
Reception of stimuli and transmission of information
Functions of senses
