C5 What functions does the skin have? (teacher instructions)

Experimentation instructions for Experimento | 10+:
Background information on the content and practical information on conducting the experiment "What functions does the skin have? - The skin as a sense organ". This experiment comprises three subexperiments.


The suggested experiments can be carried out by up to eight groups of students. They are particularly suitable as an introduction to the sense of touch from a sensory-physiological point of view. These instructions provide notes for linking the experiments to the curriculum and ideas for further study.

The experiment comprises three subexperiments:
· How does skin react to touch?
· How does the skin perceive cold and heat?
· How does the skin distinguish between different temperatures?

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.

C2 Carbohydrates as providers of energy for metabolism (student instructions)

Experimentation instructions for Experimento | 10+:
Detailed instructions and questions for students on conducting the experiment "Carbohydrates as providers of energy for metabolism - Starch and sugar". This experiment comprises two subexperiments.


The experiment comprises two subexperiments:
· Potatoes contain starch
· Hydrolysis of starch

For each subexperiment, the students are first provided with an overview of the materials to be used and safety information. This overview is followed by the detailed, step-by-step instructions for conducting the experiment. Afterwards, the students are asked to note their observations. Specific questions are used to guide the students as they analyze the results of the experiments. At the end, the students are asked probing questions related to the experiment (an answer sheet is available for teachers).

Notes:
· Observe the safety information in the instructions as well as the applicable safety guidelines for your school and discuss it with your students.
· This student instruction is also available in Word format (doc-file).

C1 We burn sugar (answer sheet)

Answer sheet:
For the student experimentation instructions of the same name.

The answer sheet contains sample answers to all questions asked in the student experimentation instructions. In some cases, the answers are very short, often only in the form of key words. Depending on the learning objective, they can be augmented and enlarged upon with additional material from textbooks or Internet research.
Likewise, the answer sheet will be elaborate on the analyses for the individual subexperiments, but only in cases where experience shows that there could be difficulties.

You will find more detailed information in the related experimentation instructions "C1 We burn sugar (student instructions)", which are available on the media portal of the Siemens Stiftung.

B6 Renewable energies (teacher instruction)

Experimentation instructions for Experimento | 10+:
Background information on the content and practical information on conducting the experiment "Renewable energies - Sun, water, wind, hydrogen, and fuel cell". This experiment comprises four subexperiments.


The experiment comprises four subexperiments:
· Electrical energy from the radiant energy of light
· Electrical energy from hydropower
· Electrical energy from wind power
· Conversion of electrical energy into chemical energy and vice versa

The sequence of subexperiments on photovoltaics, hydropower, wind power, and hydrogen technology provides a highly topical introduction to renewable energies. However, the subexperiments require a lot of time and cover a wide range of content. For this reason, the experiments are particularly useful as a project or for a project day on the subject of energy transition. Due to the large scope, it is also highly unlikely that the students will be able to work through the underlying scientific topics during the experiment. Provided that they have certain basic knowledge, however, the students can optimally verify their current knowledge of physics and chemistry based on the subexperiments. Alternatively, the individual subexperiments can also be used as an introduction to one of the basic scientific topics, based on a real-world technical application.

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.

B3 How does waste separation work? (student instructions)

Experimentation instructions for Experimento | 10+:
Detailed instructions and questions for students on conducting the experiment "How does waste separation work? - Separating materials by density and magnetism". This experiment comprises two subexperiments.


The experiment comprises two subexperiments:
· Separation of a mixture of solid substances
· Principle of the separation of aluminum from other non-ferrous metals

For each subexperiment, the students are first provided with an overview of the materials to be used and safety information. This overview is followed by the detailed, step-by-step instructions for conducting the experiment. Afterwards, the students are asked to note their observations. Specific questions are used to guide the students as they analyze the results of the experiments. At the end, the students are asked probing questions related to the experiment (an answer sheet is available for teachers).

Notes:
· Observe the safety information in the instructions as well as the applicable safety guidelines for your school and discuss it with your students.
· This student instruction is also available in Word format (doc-file).

Pedagogical/didactic introduction Experimento | 10+

Teaching methods:
Information on how to use Experimento | 10+ for teaching.

Teachers are here introduced to the pedagogical/didactic concept of using Experimento | 10+ for teaching. Most of these easy-to-perform, freehand experiments can be conducted interdisciplinarily. They are suited for an introduction to new topics or to exercise material already learned. The experiments relate to the student's everyday life, support independent learning, focus on competence and are suited for different age groups.

Nerve conduction in the skin

Information sheet:
A stimulus is received by a receptor and transmitted across the nerve cells to the brain.

The cells of the nervous system are introduced and the basic structure of a nerve cell is described. The process of transmitting a nerve impulse from the skin to the brain is explained based on saltatory conduction.
In addition, the different skin sensors are introduced:
· Free nerve endings
· Tactile corpuscles (Meissner?s corpuscles)
· Cold receptors (Krause?s corpuscles)
· Heat receptors (Ruffini?s corpuscles)
· Pressure receptors (Pacinian corpuscles)
