B7 Capacitor, hydrogen, redox flow (teacher instructions)

Experimentation instructions for Experimento - 10+:
Background information on the content and practical information on conducting the experiment "Capacitor, hydrogen, redox flow - We store renewable energy". This experiment comprises three subexperiments.


The experiment comprises three subexperiments:
· Storage of electrical energy as chemical energy (hydrogen)
· Direct storage of electrical energy in capacitors
· Storage of electrical energy in a zinc-iodide cell (redox flow)

The sequence of subexperiments on energy storage provides a topical introduction to a subject that is especially important for the use of renewable energies. However, the subexperiments require a lot of time and cover a wide range of content. For this reason, the experiments are particularly useful as a project or for a project day on the subject of energy transition. Due to the large scope, it is also highly unlikely that the students will be able to work through the underlying scientific topics during the experiment. Provided that they have certain basic knowledge of physics and chemistry, though, the students can optimally verify this knowledge based on the subexperiments. Alternatively, the individual subexperiments can also be used as an introduction to one of the basic scientific topics, based on a real-world technical application.

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.

B1 Water cycle (teacher instructions)

Experimentation instructions for Experimento - 10+:
Background information on the content and practical information on conducting the experiment "Water cycle - Evaporation from plant leaves".


This very simple experiment is ideally suited as an introduction to various topics. For example, it can be used in geography class to study the water cycle and the climate, and in biology class, to study water as the basis of life and its importance in plant metabolism. This experiment can even be used in physics and chemistry to present the states of matter using a real-world example. The materials and apparatus supplied allow eight groups of students to conduct the experiments simultaneously.

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.

B2 Greenhouse effect in a drinking cup (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 "B2 Greenhouse effect in a drinking cup (student instructions)", which are available on the media portal of the Siemens Stiftung.

B4 We produce drinking water (student instructions)

Experimentation instructions for Experimento - 10+:
Detailed instructions and questions for students on conducting the experiment "We produce drinking water - Methods of purifying water". This experiment comprises three subexperiments.


The experiment comprises three subexperiments:
· Rough purification of contaminated water with silica sand, activated carbon, and filter paper
· Fine purification of water with membrane filter
· Fine purification of water with hollow fiber membrane filter

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).

This is how I damage my sense of hearing

Interactive graphic (with audio):
What happens with my hearing or hearing ability if I listen to music which is too loud, for example, with earphones, or I listen to it for too long?

This example clearly shows that after two hours of listening to loud music, a person?s ability to hear is reduced significantly.

Information and ideas:
When it comes to drugs and alcohol, young people are often no longer receptive to good arguments. This is different when it comes to volume. Young people subject themselves to excessive volume usually without thinking about it. The result that can be tested on oneself that listening to loud music for just two hours leads to a clear deterioration in hearing does give them food for thought.

Noise consumption and leisure-time activities
