AQA Chemistry/Trilogy GCSE, Bonding 6-mark question development

This resource is a self‑directed, learning activity designed to support students in developing high‑quality responses to a 6‑mark GCSE chemistry question on relating the bonding and structure of a substance to the melting point.
The lesson centres on a classic exam question comparing magnesium oxide and carbon dioxide, guiding students to move from foundational knowledge to extended, evaluative responses. Students begin by self‑assessing their readiness to answer the question, promoting independence and metacognition.

Those requiring support complete a structured sequence of tasks aligned to SOLO taxonomy, progressing through:
identifying and defining different types of bonding,
describing particles, structures and intermolecular forces,
explaining links between bonding, structure and physical properties,
applying knowledge to unfamiliar examples and predictions.

Students then return to the original 6‑mark question to produce an improved, independent answer.

An additional challenge evaluation question extends higher‑attaining students by requiring them to critique a simplified explanation, explicitly addressing the role of structure as well as bonding type, with model answers provided to support self‑assessment and teacher feedback.

Key features:
Exam‑style 6‑mark questions with model answers
SOLO‑based progression to support stretch and scaffolding
Encourages student independence and reflection
Suitable for GCSE Chemistry and Trilogy Science
Ideal for lessons, revision, or intervention

Best used for:
Developing extended responses, improving exam technique, and deepening understanding of bonding and structure through student‑led learning.
