B6 Renewable energies (student instructions)

Experimentation instructions for Experimento - 10+:
Detailed instructions and questions for students 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

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).

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.

A3 Lemon batteries and other batteries (teacher instructions)

Experimentation instructions for Experimento - 10+:
Background information on the content and practical information on conducting the experiment "Lemon batteries and other batteries - Electricity from chemical energy". This experiment comprises six subexperiments.


The sequence of the subexperiments forms a learning unit that builds upon itself - from the first qualitative investigation of the "electrochemical cell" phenomenon based on simple fruit and vege-table batteries, to the explanation based on the electrochemical series of metals, to the building of powerful accumulators and batteries. This unit can be used both to develop the subject of electro-chemistry and to put knowledge learned about redox chemistry into practice. Of course, the subexperiments can also be conducted individually. Teachers may freely choose the degree of emphasis for each topic. The materials and apparatus supplied allow eight groups of students to conduct the experiments simultaneously.

The experiment comprises six subexperiments:
· How well does the "fruit and vegetable battery" work?
· The "lemon battery": What role does each element play?
· The "lemon battery" without the lemon
· Boosting battery performance
· Spontaneous copper plating?
· A professional zinc-copper battery

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.

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.
