The Upper Secondary Chemistry Complete Bundle is a comprehensive, concept-driven assessment package designed specifically for bilingual (CLIL) and advanced English-language chemistry instruction. It combines all individual tests from this series into one coherent bundle, offering teachers a consistent, academically rigorous assessment framework across the entire upper secondary chemistry curriculum.
Each test in this bundle is built around a detailed, continuous background text written in clear, subject-appropriate English. Rather than presenting isolated facts, the texts explain chemical principles in context, allowing students to develop scientific language competence while deepening conceptual understanding. This makes the bundle particularly suitable for CLIL classrooms, where subject learning and language development must go hand in hand.
The tasks in every test follow a structured three-level progression:
Level I focuses on factual understanding and correct use of terminology,
Level II requires analysis of chemical processes and relationships,
Level III challenges students to evaluate models, applications and implications of chemistry in real-world contexts.
This structure ensures that students are not only assessed on knowledge, but also on analytical reasoning, scientific argumentation and evaluation skills, all of which are essential for upper secondary education.
A key strength of the bundle is the detailed 100-point marking scheme included with every test. The marking guides clearly differentiate between content knowledge, structure of argumentation and use of subject-specific language. This supports transparent, reliable and competence-oriented assessment, particularly important in bilingual settings.
Thematically, the bundle covers all major fields of upper secondary chemistry, including organic chemistry, biomolecules, enzymes, metabolic pathways and biotechnology. The consistent structure across all tests allows teachers to use the bundle flexibly – either sequentially over the school year or selectively for specific units.
This bundle is ideal for teachers who:
teach chemistry in English or CLIL contexts,
value concept-based learning over rote memorization,
want ready-to-use yet academically demanding assessments,
and aim to strengthen both scientific and linguistic competencies.
The “Redox Reactions and Oxidation Numbers” test is designed for upper secondary chemistry and CLIL classrooms and focuses on developing a conceptual understanding of electron transfer processes. A comprehensive background text introduces oxidation and reduction as coupled processes and explains oxidation numbers as a formal tool for analyzing redox reactions. Students learn how to identify oxidation and reduction steps and how to balance redox equations systematically. A key didactic feature of this assessment is its emphasis on model awareness. Oxidation numbers are explicitly presented as simplified representations, encouraging students to critically reflect on their usefulness and limitations. The test includes three structured tasks progressing from knowledge reproduction to analysis and critical evaluation. A detailed 100-point marking scheme ensures transparent and reliable assessment in upper secondary contexts.
Klassenstufen: EF (10./11. Jhg.), Q1 (11./12. Jhg.)
The “Acids, Bases and pH Value” test is designed for upper secondary chemistry and CLIL classrooms and focuses on a concept-based understanding of acid–base chemistry. Rather than treating pH as a purely computational tool, this assessment emphasizes chemical reasoning and model awareness. A comprehensive explanatory text introduces the Brønsted acid–base concept, highlighting proton transfer and conjugate acid–base pairs. Students explore how aqueous equilibria are linked to water autoprotolysis and how the pH value emerges as a logarithmic measure of hydronium ion concentration. Special emphasis is placed on the distinction between strong and weak acids and bases and the role of equilibrium in determining pH. Students analyze how dissociation degree, equilibrium constants and concentration interact, supporting scientific literacy in bilingual chemistry education. The test includes three structured tasks progressing from knowledge reproduction to analysis and critical evaluation of the pH concept as a model. A detailed 100-point marking scheme ensures transparent assessment and supports reliable grading in upper secondary contexts.
Klassenstufen: Q1 (11./12. Jhg.), Q2 (12./13. Jhg.)
The “Electrochemistry: Galvanic Cells and Electrolysis” test is designed for upper secondary chemistry and CLIL classrooms and focuses on the relationship between redox reactions and energy conversion. A comprehensive background text explains how galvanic cells convert chemical energy into electrical energy through spatially separated oxidation and reduction processes. Students analyze electron flow, half-reactions and the role of electrochemical series. A strong didactic emphasis is placed on the comparison between galvanic cells and electrolysis, highlighting the direction of energy transfer and the role of external voltage. Students are encouraged to reflect on model limitations and real-world applications. The assessment includes three structured tasks covering knowledge, analysis and critical evaluation. A detailed 100-point marking scheme ensures transparent assessment.
Klassenstufen: Q1 (11./12. Jhg.), Q2 (12./13. Jhg.)
The “Alkanes, Alkenes and Alkynes” test is designed for upper secondary chemistry and CLIL classrooms and focuses on understanding hydrocarbons through structure–reactivity relationships. A comprehensive background text explains saturated and unsaturated hydrocarbons using real chemical equations, including substitution, addition and combustion reactions. Students analyze why bonding type determines chemical behavior and industrial relevance. Special emphasis is placed on real-world applications, such as fuels, plastics and welding gases, and on the environmental impact of hydrocarbon use. This supports scientific literacy and critical evaluation in bilingual chemistry education. The assessment includes three structured tasks progressing from knowledge reproduction to analysis and critical evaluation. A detailed 100-point marking scheme ensures transparent assessment in upper secondary education.
Klassenstufen: Q1 (11./12. Jhg.), Q2 (12./13. Jhg.)
