If you've had problems with this unit and you would like to reinforce some of the concepts, you can do these extra activities. Hand them in as soon as possible so I can consider them for the next grade mark, I recommend Monday 15th February at the latest!

Write stimuli, receptor, coordination system, response and effector for the following situations.
a) A man hears music and begins to clap.
b) A zebra sees and hears a lion and runs away.
c) A boy touches a flame and pulls his hand away quickly.
d) The temperature goes up and  a man begins to sweat.
e) A chamaleon sees a predator and changes colour.
