Outline Scheme of Work: B5 The human body – staying alive Suggested teaching time for chapter: 31/8 hours B5.1 How do substances get into, out of and around our bodies? Lesson Statements Teaching activities Notes 1 B5.1.1 describe some of the substances transported into and out of the human body in terms of the requirements of cells, including oxygen, carbon dioxide, water, dissolved food molecules and urea This content could be delivered using a brainstorming type of exercise thinking about the requirements of cells and the waste products of cellular processes e.g. respiration and linking this to transport mechanisms. Alternatively, learners could be set a research task where they are required to report back to the class in some form their findings about cellular transport. From the Key Stage 3 Programme of Study: The role of diffusion in the movement of materials in and between cells. 2 B5.1.2 explain how the cell membranes of animal cells are related to diffusion, osmosis and active transport The content from the previous lesson links directly to considering the need for membranes and to content in Chapter B3 about diffusion, osmosis and active transport. Membrane transport A clear overview of membrane transport along with a multiple step animation will allow learners to develop a basic understanding of the transport processes. This could be an ideal homework activity. THINKING CONCEPTUALLY Membrane structure This game by Bioman Games allows learners to develop an understanding of membrane structure. For the more able learners a thorough and detailed animation is available that learners can use to produce their own revision resource. THINKING CONCEPTUALLY
B5.2 How does the nervous system help us respond to changes? Lesson Statements Teaching activities Notes 1 B5.2.1 explain how the components of the nervous system work together to enable it to function, including sensory receptors, sensory neurons, the CNS, motor neurons and effectors These introductory ideas are rarely found covered as isolated content in online activities but the two starter activities found are quite good and the information on page of the BBC Bitesize site covers the content quite well. Essentially, learners need to be familiar with the idea of stimulus receptor CNS effector response. activity focuses on these ideas and links them to reflex arcs, as does card sort activity. 2 B5.2.2 explain how the structures of nerve cells and synapses relate to their functions The activity found allows learners to label diagrams of nerve cells and describe the structure and function of the parts of the cells. is a placemat style worksheet enabling learners to label nerve cells and then use ‘fill the gaps’ to describe their functions. Structure of neurons Learners can develop an understanding by testing themselves on the structure of a motor neuron. They can then progress to develop an understanding of how a synapse works by watching a short video clip and working through a step by step explanation of the process. THINKING CONCEPTUALLY is a presentation and worksheet that cover the content about synapses at the right level. is an animation that shows simply how a synapse works. It can also be manipulated to show the effect of a drug.
