Natural Polymers: Carbohydrates — Interactive Lesson (Ages 14–16)

Yam, rice, garri and bread all rely on natural polymers built from glucose. This 21-slide interactive lesson on carbohydrates takes pupils from first ideas to exam-style explanations, with 12 self-marking activities and nothing to prepare beforehand.

Teaching Natural Polymers: Carbohydrates in GCSE Chemistry

Pupils classify monosaccharides, disaccharides and polysaccharides, explain starch, cellulose and glycogen as polymers of glucose, and describe hydrolysis by acid or the enzyme amylase. They carry out the iodine test for starch and Benedict's test for reducing sugars, including why sucrose gives a negative result.

What Pupils Will Learn

• Describe carbohydrates and their general formula.
• Explain how starch and cellulose are polymers of glucose.
• Describe the hydrolysis of starch.
• Carry out the iodine and Benedict's tests.
• Compare starch, cellulose and glycogen.
