B5 We build a thermal solar plant (teacher instructions)

Experimentation instructions for Experimento | 10+:
Background information on the content and practical information on conducting the experiment We build a thermal solar plant - With a magnifying glass and mirror. This experiment comprises two subexperiments.

The two subexperiments on concentrating sunlight with a lens and a mirror are particularly suitable in physics class for the students to become acquainted with some laws of ray optics and thermo-dynamics based on a highly topical subject or to verify material already learned. But the experiments can also be used for a project day on renewable energy or energy transition. The materials and apparatus supplied are sufficient to allow four groups of students to work simultaneously.

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

· 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.

Redox flow cell

Schematic diagram:
The redox flow cell is an accumulator and works, so to speak, with liquid electrode materials, e.g., with zinc (Zn) and bromine (Br).

The graphic shows the flow of the electrode material during discharging of the cell. Two graphite electrodes (black surfaces) collect the current. Zinc is oxidized at its electrode, while the bromine is reduced at its electrode.
During charging, voltage is applied and the two solutions are pumped past the electrodes again.

Information and ideas:
What advantages does this process have over conventional galvanic cells?

Experiments on photosynthesis

Web resource:
Experimentation instructions and ideas on the subject of photosynthesis for every school grade.

This resource with 30 pages compiles experiments on various highlighted topics related to photosynthesis in the broadest sense:
· Sun as an energy source
· Chlorophyll
· Energy from the sun and water
· Oxygen as a by-product of photosynthesis
· Chemical energy
· Energy efficiency.

Information and ideas:
This collection of experiments was formed as part of a continuing education course for biologists at the Schulbiologiezentrum Hannover (Hanover school biology center).

Water as an energy source

Information sheet:
How do you use "water" as a energy source?

Water covers around two-thirds of planet earth. Water is a carrier of different forms of energy. The hydropower (mechanical energy) of rivers and lakes is one of the oldest forms of energy used. However, water is also a carrier of thermal and chemical energy. In the case of geothermal power or fuel cell technology, for example, we convert these forms of energy to useful energy for people. No matter what form of energy we use, it is always converted without carbon dioxide emissions!

Information and ideas:
The use of hydropower over the course of history intersects with history studies.

Instructions for making a zinc-iodide cell

Teaching method:
Teacher instructions for making a simple zinc-iodide cell.

The zinc-iodide cell or zinc-iodide battery is an ideal model to use at school for understanding how a rechargeable battery works.
The closed-container design suggested here provides greater safety during the experiment, and the ability to reuse the materials protects the environment and goes easy on the wallet.

Information and ideas:
As a supplement to experiment "B7 Capacitor, hydrogen, redox flow - We store renewable energy." This experiment is part of Experimento | 10+, one of the three modules of the Experimento project of the Siemens Stiftung, which includes teacher seminars and kits with experimentation materials in addition to the instructions.

B6 Renewable energies (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 for Experimento | 10+ "B6 Renewable energies (student instructions)", which are available on the media portal of the Siemens Stiftung.

B6 Renewable energies (worksheet 3)

Worksheet for subject teaching in English:
For the student experimentation instructions of the same name. Methodology tool: word string developed by Josef Leisen and Heinz Klippert.

Note: This worksheet has been developed especially for subject teaching in English and for language-sensitive subject teaching. It uses the word string methodology tool developed by Josef Leisen and Heinz Klippert. The word string supports the introduction of typical sentence structures in subject teaching and is a language aid for the students.
Students whose native language is not English and who do not have strong English skills receive support and training in understanding the technical vocabulary. They work with the specialized vocabulary and in this way acquire the ability to communicate about specific subjects.
