In this engaging activity, students work in pairs to explore the key concepts of alkenes, focusing on pi and sigma bonds and their significance. One student, the "skiver," explains these concepts, while the "proper student" provides feedback to clarify misunderstandings. The session continues with a focus on electrophilic addition reactions of alkenes, enhancing comprehension through peer teaching. Additionally, groups create role plays or analogies to illustrate polymerization processes, ensuring students grasp the foundational chemistry concepts necessary for their GCSEs.
E N D
In pairs (one skiver and one proper student) • The skiver explains the pi and sigma bonds in alkenes and their importance. • Proper student then feeds back and fills in any gaps or misunderstanding • 5 minutes
In pairs (one skiver and one proper student) • The skiver explains the electrophillic addition reactions of alkenes and how they occur • Proper student then feeds back and fills in any gaps or misunderstanding • 10 minutes
Polymerisation • What do you remember form GCSE 3 minsto discuss
Role play • In groups can you make a role play or analogy to explain how polymerisation takes place for my year 10s
