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).

; Physics and chemistry of water: Energy storage and release using water as an example

Simulation:
Principle of energy storage and release with water as example, animated presentation.

Strictly speaking, energy is stored not only in molecular movements and vibrations but also in the transition between physical states. During evaporation and condensation, water absorbs and releases a relatively large amount of energy owing to the strong hydrogen bridge bonds.

Information and ideas:
As background for the topic "water as a means of energy storage" and "water in power generation", which is also important for thermal power engines, such as the steam engine. Even without going into thermodynamics, it is clear where steam engines get their energy from: The superheated steam contains a great deal of energy. Given the same volume, this corresponds to a high pressure that can move a piston.

Efficiency of energy conversion

Interactive graphic:
Comparison of the typical efficiencies of energy conversion and energy transfer processes.


The efficiency of selected everyday energy conversion and energy transfer processes is shown, together with the designation of the energy forms of the source and useful energy. The graphic also shows the form in which energy "losses" occur during conversion.

A5 How do solar cells connected in series or in parallel behave when shaded? (worksheet 5)

Worksheet for subject teaching in English:
For the student experimentation instructions of the same name. Methodology tool: picture sequence 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 picture sequence methodology tool developed by Josef Leisen and Heinz Klippert. The picture sequence is used to train students how to correctly comprehend and then explain the chronological and logical sequences of events.
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.

Energy Saving: Tracking down "energy hogs? (student instructions)

Experimentation instructions:
The object is to use a tool for measuring the power consumption of electrical appliances to determine how much electric power appliances consume.

The basics of current, voltage, power, time, and energy are reviewed. This is the background knowledge needed to understand the energy consumption measurements described subsequently. By extrapolating, you can see that even "small? continuous loads can mount up to appreciable energy consumption over the year.

Information and ideas:
· Observe the safety information in the related "Tracking down ?energy hogs? (teacher information)? teaching methods, which are available on the media portal of the Siemens Stiftung, as well as the applicable safety guidelines for your school and discuss them with your students.
· A digital electric power consumption meter is needed to conduct the experiment.
· The answers to the questions contained in the experimentation instructions are found in the anwer sheet of the same name.
