C6 Skin and hygiene (student instructions)

Experimentation instructions for Experimento | 10+:
Detailed instructions and questions for students on conducting the experiment "Skin and hygiene - Why do we wash our hands?". This experiment comprises two subexperiments.


The experiment comprises two subexperiments:
· What happens when you wash your hands?
· The pH value of skin

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).

C3 How does human digestion break down fats? (teacher instructions)

Experimentation instructions for Experimento | 10+:
Background information on the content and practical information on conducting the experiment "How does human digestion break down fats? - Saponification of edible oil". This experiment comprises two subexperiments.


These simple experiments for the emulsification and saponification of fats are well suited as an introduction to the topic of digestion and metabolism in the human body. Starting from the experiment that merely demonstrates that fats can be split into fatty acids, the topic must then be related to human digestion. These teacher instructions provide information and suggestions for this. The materials and apparatus supplied are sufficient to allow eight groups of students to conduct the experiments simultaneously.

The experiment comprises two subexperiments:

· We emulsify oil
· Saponification of edible oil

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.

B4 We produce drinking water (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 "B4 We produce drinking water (student instructions)", which are available on the media portal of the Siemens Stiftung.

The pH value in the human body

Information sheet:
Brief introduction to the topic of acids, bases, and pH value. What role does the pH value play in the human body?

The basics of acids and bases are taught, pH value is defined, and measurement methods to determine the pH value are outlined. Building upon this information, the pH value situation in the human body is described. Two specific examples are looked at in more detail in this context: The pH value of skin and the significance of the pH value of food for healthy nutrition.

Information and ideas:
Brief overview information is provided here. The theoretical part requires further study in class; topics related to everyday issues can be explained in more detail through reports given by the students.
