Methodologically, learners read clear, structured declarative sentences focused on everyday social interaction, empathy, and friendship. They then verify and deepen their reading comprehension by formulating concise written answers in English to targeted open questions regarding key details, central messages, and cause-and-effect relationships in the text.

Competencies:

• Reading & Decoding Skills (English): fluent reading, reliable decoding of simple connected sentences, and structural understanding of basic English texts
• Reading Comprehension & Text Analysis: extracting explicit details, identifying central themes, and understanding simple cause-and-effect relationships
• Writing & Expression Skills (English): formulating clear, short written responses in English using appropriate thematic vocabulary

Target Group: Grade 5 and above

 Students consolidate their multiplication skills and apply them in a playful problem-solving context.

Content and Methods: The worksheet is designed as an escape-room activity. Students solve several multiplication problems, count how often certain results occur, and use this information to determine individual digits of a numerical code. At the end, they combine the digits to form the complete code and “open” the chest.

Skills:

• Solve multiplication problems accurately
• Compare and evaluate results

Target Group and Level: suitable for primary school students (Grades 2–4)

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)

Objective: This worksheet uses the cooperative learning method known as the “group puzzle” to teach complex concepts in chemistry and atomic physics. The goal is for students to gain a deep understanding of the selected topic through self-directed learning and peer teaching.

Content and Methods: The content is taught using a structured five-phase model that combines cooperative and independent learning: In home groups, each member takes on a specific subtopic, which is then explored in a subsequent “expert phase” in groups of students with the same subtopic, using informational texts and in-depth tasks. Afterward, the students return to their core groups, share their knowledge with one another, and consolidate their findings together before moving on to a cooperative work phase in which they solve complex tasks that can only be mastered by combining all the individual aspects. The process concludes with a joint evaluation in a plenary session and a reflection on the learning process.

Competencies:

• Subject-Specific Competence: Acquiring in-depth knowledge of a topic in chemistry
• Social Competence: Fostering teamwork and communication skills through the “expert” model
• Methodological Competence: Applying cooperative learning methods to independently process information and convey knowledge
• Transferability: Applying expert knowledge to hypothetical scenarios, such as the discovery of new elements

Target Audience and Level: High School

Objective: This workbook explores a historical and materials-science phenomenon: the production of casein, an early milk-based bioplastic. Students work as a team of researchers to investigate how the organic components of liquid cow’s milk can be transformed into a solid plastic through the action of acid.

Content and Methods: The content is conveyed through a combination of historical contextualization, experimental laboratory work, and material analysis: Starting with the question of how a solid material can be produced from milk, students explore the composition of milk and the effect of acids on proteins. They then experimentally extract casein, document the course of the reaction, and examine the properties of the resulting bioplastic. Finally, the results are used in a scientific application to evaluate the historical significance and material properties of casein as an alternative to plastic.

Competencies:

• Technical expertise: Understanding of protein denaturation (acid precipitation of milk protein/casein) and the classification of galalith as a historical bioplastic
• Knowledge acquisition: Planning, conducting, and systematically documenting a preparative organic chemistry experiment (filtration, solid isolation)
• Materials and testing skills: Criteria-based analysis of the physical properties of a self-produced solid
• Argumentation and language skills: Writing a technically sound report using precise scientific explanations

Target audience and level: Middle school

Objective: This worksheet explores the electrochemical fundamentals of galvanic cells and how a lemon battery works in the context of modern, sustainable technology development. Students take on the role of a startup research team to experimentally and ecologically evaluate the suitability of a lemon as an environmentally friendly electrolyte, as well as the efficiency of various electrode pairings.

Content and Methods: The content is taught by combining theoretical fundamentals, experimental data collection, error analysis, and sustainability assessment: First, students explore the structure and functioning of electrochemical cells as well as the underlying redox reactions. They then test their hypotheses in an experiment, document measurement data, and analyze typical sources of error in the laboratory.

Target audience and level: Grades 7 and above

Objective: This worksheet uses a fictional criminal case to introduce students to the basics of nuclear chemistry and atomic structure in a playful way. Students examine β⁻ decay using the example of an isotope and learn to quantitatively determine atomic composition and radioactive decay processes based on atomic and mass numbers.

Content and Methods: The material is taught by combining contextual learning, tabular particle analyses, and mathematical methods for describing radioactive processes. The starting point is a fictional case file in which a laboratory investigation is used to develop fundamental questions about nuclear transformations and radiation. Building on this, the isotopes are analyzed in terms of their proton, neutron, and electron counts, and nuclear reaction equations and the principle of β⁻ decay are explored. This is supplemented by a quantitative evaluation of radioactive decay using half-life calculations to determine residual amounts and sample age, before students assess their understanding in a short, summary exit ticket.

Competencies:

• Subject-specific competence: Distinguishing between basic physical and chemical concepts (isotope, atomic number, mass number) and classifying nuclear transformations
