Five senses in the human head

Labeled graphic:
The five human senses.

With the five sense organs, eyes, ears, nose, tongue and skin, the human being receives stimuli, transforms them into electrical nerve impulses which are then transmitted to the brain.
There they are processed, classified and interpreted.

Information and ideas:
Suitable as starting point. Important to point out that internal organs are involved as well as the visible organ and that the brain is necessary for the evaluation of the impulses.

Relevant for teaching:
Structure and function of a sensory organ
Reception of stimuli and processing of information
Senses discover the environment

Audio

Spatial perception

Sound:
Sequence of same sounds with varying echoes makes spatial perception clear. A sound in a living room is different to what it is in a hall.

We recognize immediately whether we are in a small room with not much space in it or whether we are walking through a big hall. The sound and the echo of our steps tell us the dimensions of the room.
We know from experience: When we find a cave, we shout into it to see how big it is, before we dare to enter it.

Information and ideas:
The recording simulates different rooms. A sequence of sounds is played. At first, you have the impression you are in a small room and, at the end, in a big hall.
There can be a class discussion about what the rooms might look like.

Relevant for teaching:
Reception of stimuli and processing of information
Senses discover the environment

C4 Sense of sight (teacher instructions)

Experimentation instructions for Experimento | 8+:
Background information on the content and practical information on conducting the "Sense of sight? experiment, which comprises four subexperiments.

The teacher instructions include information on the following: the main question, relevance to the curriculum, skills, notes on conducting the subexperiments, the research group, further research assignments, the reference to technology, and the reference to values.

The experiment comprises four subexperiments:
· Perception of colours
· Our field of vision
· You need light to see
· Where do the colors of the rainbow come from?

Vision is one of the most important senses for humans. It is through our eyes that we perceive more than two-thirds of the sensory impressions processed by our brains. When we hear a bicycle bell ring behind us, we automatically turn around. That?s because we prefer to see things with our eyes rather than just trusting our sense of hearing. In addition, our two eyes do incredible things: They provide an extremely detailed, continually updated, three-dimensional color picture of the world.
For most of us, this is completely normal; not only children, but also adults, are often unaware of everything that our eyes can actually do. Therefore it is important to sensitize children to their sense of sight early on: How do our eyes work? How can we perceive our surroundings with the aid of our eyes? What level of sensory stimulus is good for us, and when does sensory overload begin? The answers to these questions will differ depending on the individual.

Notes:
· Observe the safety information in the instructions as well as the applicable safety guidelines for your school.
· All materials mentioned in the instructions will have to be purchased directly from commercial sources.

Sense organs - sense of taste

Photo:
A healthy person has about 4,000 taste buds spread over the tongue, the inside of the cheeks and the throat.

The fact that we can enjoy the taste of our food is the result of interaction between several senses. It is not just through our mouth that we get the messages referring to the taste of food and drink. Our so-called "chemical senses", the actual sense of taste and the sense of smell work together to provide human beings with the ability to recognize a wide range of different tastes and flavours. Scientists are of the opinion that the perception of taste can be trained in a similar way to the sense of smell. They claim that gourmets should be able to train their sense of taste in the same way that perfumiers can.

Information and ideas:
Students can have a tasting session and try to recognize different drinks by tasting them when they are blindfolded:
- Cola
- Water
- Tea
- Fruit juice
- etc.

Sense organ eye

Photo:
The eye as sense organ. It does not just differentiate between brightness and colour but also shape.

The eye is a ball that is located in a cavity in our skull. It consists mainly of the cornea, the lens and the retina.
The light perceived is beamed first of all by the lens. The retina with its sensory cells is at the back of the eye, this is where the image spots arrive from where they are transmitted via the optical nerve to the brain.
In the brain the whole image is then put together.

Information and ideas:
Explanation of how the eye works can be done, for example, by showing the students a camera:
lens: lens of the camera
retina: film
brain: development of the film

Sense of rotation

Photo:
A child turns its head while sitting on a swivel chair. Why does it get dizzy?

Simple experiment for the students to try out themselves.

Information and ideas:
Typical situations which the children know from their own everyday life:
- Turning on a chair
- Rides on roundabouts
- Turning quickly in a circle
etc.

The structure of the eye

Content package for interactive whiteboards:
Individual media related to the structure of the eye are compiled here in a meaningful didactic way for teaching using an interactive whiteboard.


All media in the content package for the interactive whiteboards are included in this self-extracting file. The content package can be started simply by clicking the ".exe" file.

The content package consists of the following media:
· 3 interactive graphics with which it is possible to work through the individual parts of the eye
· 2 interactive exercises on the parts and areas of the eye
· 2 simulations related to the seeing process and the accommodation of the eye
· 3 films about the structure of the eye, the image in the eye, visual defects
· 1 photo of an eye
· 1 information sheet on the seeing process for students
· 1 worksheet (with answer sheet).

Information and ideas:
Most of the media in content package are also available as individual media on the media portal.
