Oxford AQA A Level Psychology: THE DISRUPTION OF BIOLOGICAL RHYTHMS [3.3.1 Psychology of Sleep]

This fully editable lesson explores the impact of disrupting biological rhythms, focusing on the effects of shift work and jet lag. Designed using the OxfordAQA International A-level Psychology (9685) specification, this lesson helps students understand how modern lifestyle factors can desynchronise circadian rhythms and the potential health consequences.
Key Features:

Comprehensive Lesson Slides: The lesson covers how biological rhythms are disrupted by factors such as shift work and jet lag. Students will learn about the role of endogenous pacemakers (internal body clocks) and exogenous zeitgebers (external cues such as light) in regulating circadian rhythms. Key studies, including Davis et al. (2001) on shift work and Cho et al. (2000) on jet lag, are discussed, providing insights into the effects of misaligned biological rhythms on health, performance, and well-being.

Interactive Activities: Engages students with a “Do Now” activity that prompts them to reflect on the consequences of disrupted sleep schedules. Throughout the lesson, Think-Pair-Share discussions encourage students to consider real-world scenarios, such as the experiences of night-shift workers and frequent travellers. Case studies like “Sam the Policewoman” provide opportunities for students to apply their knowledge of pacemakers and zeitgebers to practical examples, fostering critical thinking.

Assessment Materials: Includes exam-style questions with model answers to assess students’ understanding of the effects of shift work and jet lag. Students will evaluate research, discuss strategies for minimising the negative impacts (such as forward shift rotation and light management), and critically engage with the evidence, helping them develop the analytical skills required for psychology exams.
