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.

Firewood as biomass

Photo: Stacked logs Biomass, especially wood, is one of the oldest sources of energy used by humankind. The energy is "obtained” through combustion.

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.

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.

Run-of-river power plant

Simulation:Operating principle of a run-of-river power plant A run-of-river power plant is used on rivers with a very small fall in elevation and a high flow rate of water. The turbines operate nonstop, meaning they can produce electric power continuously and have very low operating costs. The river water flows through a turbine, which drives a generator, thus producing electricity. An effective head of a few meters is sufficient for run-of-river power plants, but the pressure difference is low. That’s why Kaplan turbines are often used as tubular turbines (horizontal installation) in these cases. They sometimes also have high-speed gearboxes (pit turbines).

Daniell cell (reaction equation)

Interactive graphic:
The reactions and the standard potential of the galvanic cell can be shown individually.


There are two alternatives for filling in the interactive table with the partial equations and the redox reaction:
· all cells at once
· each cell individually.
