Description

Objective: This worksheet aims to educate students about debris flows, including their natural causes, human contributions to their occurrence, and various protective and preventative measures, while also developing their comprehension and critical thinking skills regarding natural disasters.


Content and methods: The worksheet starts by engaging students with a video of a debris flow in the Swiss Alps, followed by a class discussion on what was seen, the meaning of "debris flow," and the video's setting. It then introduces tweets from a character named Amina, who experiences a debris flow during her vacation in the mountains, prompting students to reflect on their feelings in such a situation. The worksheet provides an informational text about a region prone to debris flows, discussing its geography, cultural mix, and a past disaster. Multiple-choice questions assess comprehension of this text. Further, the worksheet explains what debris flows are, how human activities (deforestation, building on steep slopes, altering rivers) contribute to them, and what preventative measures (planting trees, careful building, protecting waterways) and protective measures (retaining walls, catch basins, early warning systems) can be taken. True/false questions test understanding of these concepts. Finally, a word puzzle reinforces vocabulary related to debris flows.


Competencies:

  • Listening comprehension
  • Reading comprehension
  • Understanding of natural phenomena (debris flows)
  • Identification of cause and effect (human impact on natural disasters)
  • Problem-solving (prevention and protection measures)
  • Vocabulary acquisition


Target group: 7th-9th grade

Recognizing Greenwashing

Recognizing Greenwashing

The goal of this worksheet is to enable students to independently identify and critically examine manipulative marketing strategies in retail. Using a specific case study, they will develop the theoretical foundation needed to distinguish between genuine sustainability promises and deliberate consumer deception, so they can make informed, independent consumer decisions in their daily lives.

Content and Methods: The content focuses on the definition and strategic characteristics of greenwashing, its psychological impact, and an analysis of legal consequences. Methodologically, the worksheet combines an image-based case analysis with in-depth journalistic text analysis. A video-based summary of theoretical categories of deception and a practical, criteria-based checklist serve to reinforce knowledge and facilitate active application to students’ own consumer behavior.

Competencies:

Analytical Competence: Students can systematically deconstruct visual design elements, price placements, and advertising messages in digital user interfaces.

Substantive Competence: They understand the definition of the technical term “greenwashing” and can distinguish between vague marketing phrases and verifiable sustainability labels.

Critical thinking skills: Students are able to critically evaluate the discrepancy between corporate sustainability reports and actual environmental impacts.

Reflective thinking skills: They can critically examine their own susceptibility to manipulative sales strategies and identify alternative courses of action.

Target audience and grade level: Intermediate (8th-10th grade)

The impact of AI on the environment

The impact of AI on the environment

Objective: The worksheet aims to raise learners' awareness of the environmental impact of artificial intelligence (AI). It trains them to critically analyse the energy and resource consumption of data centres in order to develop strategies for the environmental sustainability of AI technology, particularly through the use of renewable energies.


Contents and methods: The worksheet begins with a warm-up on the learners' personal attitudes towards AI and climate change, followed by information about AI data centres in a selected country/city. Learners analyse advantages and environmental risks using text and cause-and-effect analyses. Methods such as group research, perspective changing and decision-making encourage reflection on sustainability and concrete measures for environmental responsibility.


Competencies:

  • Sustainability awareness: Understanding the ecological footprint of digital technologies (energy and resource consumption).
  • Critical analysis: Weighing technological advantages (climate research, smart farming) against environmental risks.
  • Problem solving: Developing concrete strategies to promote energy efficiency and the use of green energy sources for AI.
  • Understanding of roles: Making informed political decisions from an environmental policy perspective.


Target group and level: Years 8–10 (middle school)


ESD:

  • 12: Responsible consumption and production patterns: This addresses the challenge of raw material extraction (rare earths) and the need for recycling and sustainable procurement.
  •  13: Climate action: The text highlights the role of AI in reducing global emissions and in climate research.
