Storage power plant

Graphic:Operating principle of a storage power plant In a storage power plant, naturally flowing water is dammed up by means of an artificial reservoir and stored for times of peak demand. The accumulated water is then fed to the turbines of the low-lying power plant via penstocks. All the potential energy of the water in the storage reservoir is thus an energy store for times of peak demand. Smaller storage power plants use Pelton turbines, while large storage power plants (high pressure and large volume of water) use Francis turbines.

Solar electric power plant on open space ("solar field,” "solar park”)

Photo: Photovoltaic power plant in a meadow ("open-space installation").Information and ideas:The photo is suitable for demonstration purposes and contains lots of starting points thematically. Starting from the photo, both the sun as an energy source and also the technological developments associated with it (for example photovoltaics) can be covered. In addition, the economic and social aspects of energy supply can also be discussed.

B6 Renewable energies (teacher instructions)

Experimentation instructions for Experimento - 8+:Background information on the content and practical information on conducting the "Renewable energies” experiment, which comprises four subexperiments.The teacher instructions include information on the following: the main question, relevance to the curriculum, skills, notes on conducting the subexperiments, the research group, and further research assignments.The experiment comprises four subexperiments:• Harnessing solar energy as heat (1)• Harnessing solar energy as heat (2)• Harnessing the energy of water• Harnessing the energy of windThe students are growing up in an era when global environmental problems, especially climate change, are frequently discussed. It is important that the students not only understand the problems, but also recognize possibilities for solving them (for example, renewable sources of energy). The following experiments provide an opportunity for the students to work with renewable energies (sun, water, and wind as energy sources).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.

Renewable energies

Multiple choice test:Eight questions on the topic of renewable energy. Answers are provided; the correct answers are to be checked. One or more answers may be correct for each question. The test can be conducted in one of two ways. • Each answer is checked immediately. If the answer is incorrect, the student can repeat the question.• The answers are not checked until the end of the test. Incorrect answers can be corrected at the end of the test. When all questions have been answered correctly, students have the option of printing a personalized certificate.Information and ideas:The second test mode is particularly suitable for fast test rounds.

A5.1 Solar cells (student instructions)

Experimentation instructions for Experimento - 8+:Detailed instructions and questions for students on conducting the subexperiment "A5 ‘Generating energy’ - Solar cells.”A short introductory text presents the experiment to the students. Then the research question is stated.The students make guesses and exchange ideas about possible solutions. This is followed by a list of the required materials as well as clear, step-by-step instructions for setting up and conducting the experiment in the small group. Observation questions for checking the results can be answered right on the instructions.There are also reflection questions for evaluating and understanding the experiment and establishing the reference to the opening question. An additional research project encourages the students to do further research.A further work assignment establishes a reference to technology. It shows photos of technical applications that are related to the scientific principles researched in the experiment.In "What is your opinion?” students are encouraged to discuss and reflect on value-related behavior.Documentation aids in the student instructions or a blank form to be filled out is provided for documenting the experiment.Information and ideas:• Observe the safety information in these instructions, in the teacher instructions related to the experiment, as well as in the document "Safety information on the topic of energy - Experimento I 8+” and discuss this information with your students.• Also observe the applicable safety guidelines for your school.• These student instructions are also available as a Word file.
