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.

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 (teacher instruction)

Experimentation instructions for Experimento | 10+:
Background information on the content and practical information on conducting the experiment "We produce drinking water - Methods of purifying water". This experiment comprises three subexperiments.


The suggested subexperiments are ideal for introducing the basic chemical subject of material separation based on the current topic of water treatment. These experiments allow students to verify their relevant prior knowledge in this field. For biology classes, these experiments lead in to the subject of water as the basis for life. These experiments can also be used in an interdisciplinary approach, e.g., within the context of an environmental project. Except for the hollow fiber membrane, the materials supplied allow eight groups of students to conduct the experiments simultaneously.

The experiment comprises three subexperiments:
· Rough purification of contaminated water with silica sand, activated carbon, and filter paper
· Fine purification of water with membrane filter
· Fine purification of water with hollow fiber membrane filter

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.

A5 Properties of solar cells (student instructions)

Experimentation instructions for Experimento | 10+:
Background information on the content and practical information on conducting the experiment "Properties of solar cells - Voltage, current and power". This experiment comprises six subexperiments.

The experiment comprises six subexperiments:
· First investigations with the solar cell
· Short-circuit current and no-load voltage at different distances from the lamp
· What happens when you connect solar cells in series or in parallel?
· Current and voltage with solar cells connected in series and in parallel
· How do solar cells connected in series or in parallel behave when shaded?
· Optimizing the power output of solar cells

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).

A2 Storing heat (teacher instructions)

Experimentation instructions for Experimento | 10+:
Background information on the content and practical information on conducting the experiment "We store heat - From heat store to molten salt". This experiment comprises four subexperiments.


Enough apparatus and materials are supplied to allow eight groups of students to conduct the ex-periments simultaneously. When all the subexperiments are conducted in the suggested se-quence, they form a basis for a learning unit on heat, heat storage, temperature, phase transition (states of matter), heat of fusion, and latent heat. These instructions provide explanatory notes and ideas for further study.

The experiment comprises four subexperiments:
· Water as a heat store - Not only the tea gets cold
· Water as an effective heat store - Water can stay hot longer if ?
· Heat for cold fingers - Is the heat pack a heat store?
· How the heat pack stores heat - A salt that changes between solid and liquid states

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.
