Cellular Respiration and Fermentation — Interactive Lesson (Ages 11–14)

How do cells release energy from food, and why does bread dough rise? This 18-slide interactive lesson on cellular respiration takes pupils from first ideas to exam-style explanations, with 10 self-marking activities and nothing to prepare beforehand.

Teaching Cellular Respiration and Fermentation in KS3 Science

Pupils learn that respiration is a reaction in every cell, not breathing, and write the word equation for aerobic respiration. They describe anaerobic respiration in muscles, lactic acid and oxygen debt, then explain fermentation by yeast in bread and brewing. They compare the three types and use the limewater test for carbon dioxide.

What Pupils Will Learn

• Describe respiration as a chemical reaction that releases energy.
• Write the word equation for aerobic respiration.
• Describe anaerobic respiration in muscles.
• Explain fermentation in yeast and its uses.
• Compare aerobic and anaerobic respiration.
