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

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


This experiment is an introductory experiment to the overall topic of digestion and metabolism in the human body. It is suitable as a qualitative introduction to the topic of digestion for the age group up to 16 years. However, further study of the topic of metabolism necessitates considerable basic knowledge of organic chemistry and biochemistry, which cannot be assumed until the age group 16+ or acquired then. The materials supplied allow eight groups of students to conduct the experiments simultaneously.

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

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.

B7 Capacitor, hydrogen, redox flow (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 "B7 Capacitor, hydrogen, redox flow (student instructions)", which are available on the media portal of the Siemens Stiftung.

B5 We build a thermal solar plant (student instructions)

Experimentation instructions for Experimento | 10+:
Detailed instructions and questions for students on conducting the experiment "We build a thermal solar plant - With a magnifying glass and mirror". This experiment comprises two subexperiments.


The experiment comprises two subexperiments:
· Setting fire to a strip of paper using a magnifying glass as a burning lens
· We heat water with the sun

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).

B3 How does waste separation work? (teacher instruction)

Experimentation instructions for Experimento - 10+:
Background information on the content and practical information on conducting the experiment "How does waste separation work? - Separating materials by density and magnetism". This experiment comprises two subexperiments.


The suggested subexperiments are ideal for introducing the basic chemical subject of material separation based on the current topics "environment, waste, and recycling." Subexperiment 2 would be of particular interest for a physics class. This subexperiment allows students to verify their prior knowledge of electricity and magnetism, using eddy currents and their effects as an ex-ample. If students lack this prior knowledge, the teacher should make sure to discuss these subjects before or after the experiment. These experiments can also be used in an interdisciplinary approach, e.g., within the context of an environmental project. The materials supplied allow eight groups of students to conduct the experiments simultaneously.

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

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.

B2 Greenhouse effect in a drinking cup (teacher instruction)

Experimentation instructions for Experimento | 10+:
Background information on the content and practical information on conducting the experiment "Greenhouse effect in a drinking cup - A model for illustrating climate change". This experiment comprises four subexperiments.


This very simple experiment can be used to teach students to readily recognize and differentiate the physical phenomena underlying the greenhouse effect, such as radiation, reflection, absorp-tion, and heat radiation. The students will need some prior knowledge to be able to interpret the results of the experiment. For this reason, the experiment can be used in two ways: Either as verification of material learned after an introduction of the topics mentioned above, or as an introduc-tion to the greenhouse effect, a hot topic in the news, with further study of the physical principles afterwards. The materials and apparatus supplied for this experiment allow eight groups of students to work simultaneously.

The experiment comprises four subexperiments:
· What influence does it have on the temperature if the cup is closed? - Measurements in an open cup
· What influence does it have on the temperature if the cup is closed? - Measurements in a closed cup
· What influence does the color of the absorber have? - Measurements in a closed cup with a black absorber
· What influence does the color of the absorber have? - Measurements in a closed cup with an aluminum foil absorber

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.
