Fats, Oils and Soap Making — Interactive Lesson (Ages 14–16)

From palm oil to African black soap, discover how soap is made and how it cleans. This 21-slide interactive lesson on saponification takes pupils from first ideas to exam-style explanations, with 12 self-marking activities and nothing to prepare beforehand.

Teaching Fats, Oils and Soap Making in GCSE Chemistry

Pupils describe fats and oils as esters of glycerol and fatty acids, compare saturated fats with unsaturated oils and follow saponification with sodium hydroxide, including salting out. They link the process to traditional black soap made with plant ash, explain how soap lifts grease, and compare soaps with soapless detergents in hard water.

What Pupils Will Learn

• Describe fats and oils as esters of glycerol and fatty acids.
• Compare saturated fats and unsaturated oils.
• Describe saponification — making soap.
• Explain how soap removes grease.
• Compare soaps and soapless detergents in hard water.
