Seeing and recognizing

Information sheet:
The most important steps involved in seeing, perceiving, and recognizing visual information.


Brief summary of the most important facts:
· Reception of light signals
· Accommodation
· Seeing colors and brightness
· Image evaluation and pattern recognition
· Intelligent evaluation.

Information and ideas:
Apart from the physiological processes involved in seeing, the principal object is for students to recognize that our society is a visually oriented society.

Structure of the eye - areas (matching exercise)

Interactive exercise:
The object of this exercise is to match the areas of the eye (outer, central, and inner layer) with their individual parts.


The areas of the eye can be matched using the mouse or manually.

Structure of the retina

Interactive graphic:
The parts of the retina can be labeled interactively.


An enlarged detail of the retina and its position in the human eye is displayed.
The graphic can be labeled interactively, either individually or in full. Manual labeling on the interactive whiteboard is also possible.

C4.1 Perception of colors (student instructions)

Experimentation instructions for Experimento | 8+:
Detailed instructions and questions for students on conducting the subexperiment "C4 Sense of sight - Perception of colors.?

A short introductory text presents the experiment to the students. Then the research question is stated.
The students make guesses and exchange ideas about possible solutions.
This is followed by a list of the required materials as well as clear, step-by-step instructions for setting up and conducting the experiment in the small group.
Observation questions for checking the results can be answered right on the instructions.
There are also reflection questions for evaluating and incorporating the experiment and establishing the reference to the opening question.
An additional research project encourages the students to do further research.
Documentation aids in the student instructions or a blank form to be filled out is provided for documenting the experiment.

Information and ideas:
· Observe the safety information in these instructions, in the teacher instructions related to the experiment, as well as in the document "Safety information on the topic of health - Experimento I 8+? and discuss this information with your students.
· Also observe the applicable safety guidelines for your school.
· These student instructions are also available as a Word file.

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

Relevant for teaching:
The human body
Structure and function of a sense organ
Reception of stimuli and processing of information
Senses discover the environment

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.

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.
