Beschreibung:
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.
