Noise and concentration - for example music

Photo:
You can do homework more quickly with music on? Tests show this only applies to routine tasks. Otherwise music is more like disturbing noise.

Is music relaxing pleasure or a disturbing noise? This is a very subjective matter. Objectively the answer depends on the specific situation!

Information and ideas:
This question "Music on when doing homework?" is an evergreen. Maybe an objective answer can be reached using the criteria of concentration and effectiveness?

Relevant for teaching:
Hearing defects/hearing impairment
How hearing works
Damage to the sense organs
Noise

Lorry

Photo:
The lorry is a typical road user that causes a lot of noise.

The big advantage of lorries is their flexibility. Compared to other means of transport like ships or trains though, they have several disadvantages: high energy consumption, exhaust fume emissions and noise. The lorry is a loud road user, reaching about 90 decibels on a noise level scale.

Information and ideas:
Use picture to start discussion or for illustration purposes.

Means of lighting in comparison

Graphic:
An incandescent lamp, an energy-saving light bulb, and an LED are compared in terms of costs and efficiency.

The comparison as a table shows that although energy-saving light bulbs and LEDs are more expensive to purchase, their total costs are significantly lower over a period of 10,000 hours. In addition, they are much more efficient than an incandescent lamp.

The Ear, Hearing and Hearing Impairment: Effects of noise

Schematic diagram:
The graphic shows that - apart from physical effects - sound does not become noise until it reaches the brain.

Noise has effects on the physical and mental health of human beings. What the individual subjectively considers to be noise depends on a number of factors, for example the individual's own mood.

Information and ideas:
Can be used as introduction to topic "What are the effects of noise??.
Can also be used for illustration purposes: individual parts can be covered up (and then gradually uncovered in the course of the lesson).

Relevant for teaching:
Noise: causes, effect, protection

Everyday energy-saving lighting

Photo collage:
A floor lamp with an energy-saving light bulb and an LED flashlight are shown as examples of energy-saving lighting.

Two examples of ways energy-saving lighting can be implemented in everyday life are shown.
The medium can be used as an image for discussion to introduce the topic of energy saving.
