This ready-to-teach IBDP Biology lesson pack covers A2.1 Origins of Cells, including early Earth conditions, pre-biotic carbon compound formation, the origin of self-sustaining cells, the RNA world hypothesis, LUCA, and hydrothermal vent evidence. The resources are aligned with the listed A2.1.1–A2.1.9 learning objectives and are identified as Additional Higher Level: 2 hours.
The pack includes a structured PowerPoint, student notes, and presentation notes with embedded questions, model answers, diagrams, video links, and source references. It supports teacher explanation, guided discussion, independent note completion, and retrieval-style questioning.
