Protects the body.
Layer of fat that protects organs/tissues underneath from bumps/falls
Also helps keep you warm
Main part of the skin
Contains many different cell types that perform different tasks:
  • Contains the sensory receptors
  • Contains hairs
  • Produces sweat (control body temperature)

Slide 11 - Sleepvraag

Pair-Share
Pair: Discuss and compare with your neighbour, decide on an answer
Take a look at image 5.21 different sensory receptors in your skin in your book on page 132.
Notice how some receptors are closer to the surface of the skin than others.
Talk about and try to explain: Why are some sensory receptors closer to the surface than others? 

Use sentences like:
  • The sensory receptor for ... is deeper than the one for .. because it ..
  • Being closer to the surface of the skin helps the ... receptor perform its function better because ....
  • If the ..... receptor were deeper/closer to the surface it would have trouble sensing ... because ...

Share: Talk about given answers during plenary session.
