Pearson Edexcel IAL Biology Unit 1 – Polysaccharides

Save valuable planning time with this ready-to-teach, interactive PowerPoint lesson covering polysaccharides for Pearson Edexcel International A Level (IAL) Biology Unit 1.

The lesson takes students from their prior understanding of monosaccharides, condensation and glycosidic bonds into a deeper comparison of amylose, amylopectin and glycogen.

Rather than simply memorising structures, students are encouraged to connect:

structure → bonding → branching → properties → biological function

This resource includes:

Retrieval starter on monosaccharides and disaccharides
Introduction to polysaccharides
Formation of polysaccharides from α-glucose
Condensation and hydrolysis
1,4- and 1,6-glycosidic bonds
Structure of amylose
Structure of amylopectin
Structure of glycogen
Comparison of branching in the three polysaccharides
Why polysaccharides are suitable for energy storage
Links between branching and rapid glucose release
Water potential and the advantage of storing glucose as polysaccharides
Biological application to liver glycogen
Links to cellular respiration and ATP
True/false retrieval activity
Multiple-choice questions
Data-analysis questions
Application challenges
Extended exam-style questions
Mark-scheme guidance
“Spot the Student Error” activity
Exit-ticket assessment

The lesson places particular emphasis on helping students explain biological relationships rather than simply state facts. Students practise linking a structural feature to its consequence, an important skill for Pearson IAL Biology exam questions.

Suitable for classroom teaching, revision, intervention and independent study.

Designed to save teachers planning time while providing purposeful questioning, application and exam-focused learning.

If you use this resource, I would really appreciate a review or comment on TES. Your feedback helps me improve future Biology Uncovered resources and develop materials that teachers genuinely find useful.

Pearson IAL Biology Unit 1 | Biological Molecules Bundle

Pearson Edexcel IAL Biology Unit 1 | Biological Molecules Complete Teaching Bundle Save time planning and give students a strong foundation in Biological Molecules for Pearson Edexcel International A Level Biology Unit 1. This complete bundle brings together my Biological Molecules lessons and exam-practice resources in one place. The resources are designed to help students understand the biology, apply their knowledge to unfamiliar contexts, and develop the exam technique needed for IAL Biology. The bundle covers: Importance of ions Water and its biological importance Monosaccharides and disaccharides Polysaccharides – starch, amylose, amylopectin and glycogen Lipids – triglycerides, fatty acids, ester bonds and saturated/unsaturated fatty acids Proteins – amino acids, peptide bonds, protein structure and function Biological Molecules Exam Mastery Pack What makes these resources different? The lessons are designed to go beyond simply presenting textbook content. Throughout the resources, students are encouraged to think, discuss, apply and explain. Activities include retrieval practice, hinge questions, true/false tasks, comprehension activities, application questions, data analysis, graph interpretation, common misconceptions and Pearson-style exam questions. There is also a strong focus on command words and exam technique, helping students understand the difference between questions such as describe, explain, compare, suggest and calculate. Exam Mastery Pack included The bundle also contains a dedicated Biological Molecules Exam Mastery Pack covering water, ions, carbohydrates, lipids and proteins. Rather than simply giving students questions and answers, the pack helps them learn how to use a mark scheme effectively. Students practise identifying the command word, considering the number of marks available, building linked marking points and improving scientifically imprecise answers. Answers and marking guidance are clearly presented in green, making the pack suitable for self-assessment, peer assessment, revision and teacher-led live marking. Ideal for Pearson Edexcel International A Level Biology (IAL) Unit 1: Molecules, Diet, Transport and Health Suitable for Year 12 teaching, revision, homework, independent study, intervention and exam preparation. Buying the bundle gives you 30% off compared with purchasing the included resources individually. For more Biology teaching ideas, exam techniques and resources, follow @uncoveredbiology on Instagram. If you use these resources with your students, I would really appreciate a TES review. Your feedback helps me improve future resources and helps other Biology teachers find resources that are right for their classes.
