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
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)
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.
