Describe how muscles, joints and bones work to move your body Other Broader/Cross-curricular links – PSHE/Body/Self, PE, sports science Starter: Have a think: are muscles like elastic bands? | Dispel misconceptions, ask them to think about models Recap on bones, joints, ligaments, tendons. Shoulder blade = scapula Functions of bones are – protection, support Where a bone meets (joint) Softer bit on the end of the bone (cartilage) The cushioning liquid on a join (synovial fluid) Connects bone to bone (ligaments) Muscle to bone (tendon) Revision Worksheet & Questions Main Activity Muscles –long and stretchy? Animation / video of muscle Muscle fibre ‘model’. Can change shape. Remind about Antagonistic Pair Is an elastic band a good model? How would you better represent a muscle? Cardiac –heart, what is special about it? Tendons can’t, ligaments can’t muscles can Types of muscle - smooth, skeletal, cardiac Match type of muscle worksheet + stick in book Slide w/Q: What would happen if our skeletal muscles were replaced by tendons? (so heart still works etc!) – couldn’t move Get them to write and articulate. What would happen if all skeletal muscles were replaced by cardiac muscles? Ext: if you need to make a muscle bunch up and get shorter, what do you need to use up? (energy) Takeaway Question/Plenary: How many muscles will you use on the way to break now? To have them thinking that they use muscles to move and realise/value what they have learned.
