Carbon, Allotropes and the Carbon Cycle — Interactive Lesson (Ages 11–14)

Diamonds and pencil leads are both pure carbon. Explore carbon's forms and how it cycles through the world. This 18-slide interactive lesson on allotropes of carbon takes pupils from first ideas to exam-style explanations, with 10 self-marking activities and nothing to prepare beforehand.

Teaching Carbon, Allotropes and the Carbon Cycle in KS3 Science

Pupils describe carbon as a Group 4 element that forms four bonds, then compare the structures, properties and uses of the allotropes diamond and graphite. They describe how photosynthesis, respiration, decomposition and combustion move carbon around the carbon cycle, and explain how burning fossil fuels and deforestation add carbon dioxide to the air.

What Pupils Will Learn

• Describe carbon as an element in Group 4 that forms four bonds.
• Compare the structures and uses of diamond and graphite.
• Describe the processes in the carbon cycle.
• Explain how human activities change the carbon cycle.
