A complete 6-mark extended-response worksheet on how carbon dioxide levels in the Earth’s atmosphere have changed over the last 4.6 billion years, fully aligned with the AQA GCSE Chemistry Paper 2 (Chemistry of the Atmosphere) specification.

This resource includes:

  • A command word sticky note explaining what “Describe” means and how to structure an extended answer.
  • A clear success criteria checklist based on AQA mark schemes.
  • A keywords box with essential scientific vocabulary (e.g. volcanic activity, sedimentary rocks, photosynthesis, carbonates, fossil fuels).
  • A vague 2- 3mark student answer for underlining and improvement practice.
  • A fill-in-the-gaps 6-mark model answer task with a randomised word bank and a full model version included.
  • Engaging visuals to support recall — volcano, algae, oceans, and atmosphere icons.

Perfect for:

  • GCSE Chemistry or Combined Science classes
  • Exam preparation/Interventions and 6-mark writing practice
  • Retrieval tasks or homework focused on Evolution of the Atmosphere

Students will learn to describe the sequence of processes — from volcanic activity to ocean formation, photosynthesis, and fossil fuel formation — using accurate scientific vocabulary and logical chronological order.
