brian eye

 

The G10 coordinated Science (Biology) class have been studying how the nervous system detects changes in the environment and coordinates an appropriate response. We broke down the steps required to catch a pen or football and identified the sensory, relay and effector neurons involved in this process. We then investigated reaction time but timing how long it would take the left and right hands to catch a ruler. Finally we looked at the central nervous system in more depth as we dissected a sheep’s brain and sense organs/receptors in more depth by dissecting a sheep’s eyeball. The students had a hands on experience as they passed the lens of the eye between them and could see for themselves as it changed shape in their hands.
