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).

Waste water purification (SS)

Video (02:36 minutes):
Demonstrates and describes the individual purification stages in a sewage plant.


Waste water purification in a sewage plant is usually performed in three stages: mechanical, biological, and chemical purification. The video shows the individual stations in a municipal sewage plant, accompanied by detailed explanations.
This video is suitable for further study in the higher grade levels.

Information and ideas:
A content package for interactive whiteboards that deals with sewage plants is available on the Siemens Stiftung media portal.

This video is an excerpt from the teaching DVD, "Chemischer Anfangsunterricht II - Stoffe untersuchen, messen".

B4 We produce drinking water (worksheet 1)

Worksheet for subject teaching in English:
For the student experimentation instructions of the same name. Methodology tool: film strip 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 film strip methodology tool developed by Josef Leisen and Heinz Klippert. The film strip supports coherent speaking and the correct chronological and content-related sequence of actions or 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.

B4 We produce drinking water (teacher instruction)

Experimentation instructions for Experimento | 10+:
Background information on the content and practical information on conducting the experiment "We produce drinking water - Methods of purifying water". This experiment comprises three subexperiments.


The suggested subexperiments are ideal for introducing the basic chemical subject of material separation based on the current topic of water treatment. These experiments allow students to verify their relevant prior knowledge in this field. For biology classes, these experiments lead in to the subject of water as the basis for life. These experiments can also be used in an interdisciplinary approach, e.g., within the context of an environmental project. Except for the hollow fiber membrane, the materials supplied allow eight groups of students to conduct the experiments simultaneously.

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

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.

B4 We produce drinking water (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 "B4 We produce drinking water (student instructions)", which are available on the media portal of the Siemens Stiftung.

B4 We produce drinking water (worksheet 2)

Worksheet for subject teaching in English:
For the student experimentation instructions of the same name. Methodology tool: reading strategy 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 reading strategy methodology tool developed by Josef Leisen and Heinz Klippert. A reading strategy is a sequence or a timetable of mental events with which a particular reading objective is to be achieved (source: Bimmel, 2002). Reading strategies help the students to better understand technical texts and work independently with them.
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.
