A Science teacher by trade, I've also been known to be found teaching Maths and PE! However, strange as it may seem, my real love is designing resources that can be used by other teachers to maximise the experience of the students. I am constantly thinking of new ways to engage a student with a topic and try to implement that in the design of the lessons.

This is a fully-resourced lesson that covers the content of specification point 6.3 of the AQA A-level Biology specification which states that students should understand how skeletal muscles are stimulated to contract by nerves and act as effectors. The wide range of activities included in the lesson will engage and motivate the students whilst the understanding and previous knowledge checks will not only allow them to assess their progress but also challenge them to make links to other Biology topics.

The following content is covered in detail in this lesson:

  • The ultrastructure of a myofibril
  • The roles of actin and myosin in myofibril contraction
  • The need for calcium ions and ATP in myofibril contraction
  • The roles of calcium ions and tropomyosin in cross-bridge formation
  • The roles of ATP and phosphocreatine in muscle contraction

This lesson has been designed for students studying the AQA A-level Biology course and ties in nicely with the other uploaded lessons from topic 6 such as synapses and NMJs and nerve impulses

AQA A-level Biology Topic 6: Organisms respond to changes in their internal and external environments

This bundle contains 20 fully-resourced and detailed lessons that have been designed to cover the content of topic 6 of the AQA A-level Biology specification which concerns the responses of organisms to stimuli. The wide range of activities included in each lesson will engage the students whilst the detailed content is covered and the understanding and prior knowledge checks allow them to assess their progress on the current topic as well as challenging them to make links to other related topics. Many of the tasks are differentiated to allow differing abilities to access the work and be challenged. The following sub-topics are covered in this bundle of lessons: * Survival and response in flowering plants * The protective effect of a simple reflex * The role of sensory receptors as outlined by the Pacinian corpuscle * The human retina as a sensory receptor * The differences in rods and cones that enable different sensitivity to light, colour and visual acuity * The roles of the SAN, AVN, Bundle of His and Purkyne fibres in the conduction system of the heart * The control of heart rate * The structure of a myelinated motor neurone * The factors that affect the speed of conduction of an impulse * The generation and transmission of nerve impulses * The transmission at a cholinergic synapse and a neuromuscular junction * Summation * The contraction of skeletal muscles * The structure and properties of slow and fast skeletal muscle fibres * The principles of homeostasis including negative feedback systems * The control of blood glucose concentration by the controlled release of insulin and glucagon * The causes and control of diabetes type I and II * The gross structure of the kidney * The detailed structure of the nephron * The production of glomerular filtrate * The reabsorption of glucose and water in the PCT * Maintaining a gradient of sodium ions in the medulla by the loop of Henle * The role of the hypothalamus, posterior pituitary and ADH in osmoregulation This is one of the 8 topics which have to be covered over the length of the 2 year course and therefore it is expected that the teaching time for this bundle will be in excess of 2 months If you want to see the quality of the lessons before purchasing then the lessons on responses in flowering plants, saltatory conduction, the contraction of skeletal muscles and ultrafiltration are free resources to download
