Our Grade 10 Life Science pupils recently did a Support and Movement practical, investigating bones.
There were various stations, and they had five minutes at each station to identify various bones from different animals, including human bones and X-rays, and they needed to identify the bones and relate bone structure to function. For example the tortoise shell – the vertebrae are fused, the ribs are fixed to the vertebra, and the shell is fixed to the ribs – to protect the creature. They also looked at dentitions – carnivores versus herbivores, and related that to their diet. Herbivores will have flat molars and premolars to grind the plant matter, whereas Carnivores will have long and sharp, well-developed canines and generally sharp teeth.
The adult-size horse skull is certainly one of the biggest skulls in this practical! Thank you to Mr Currie for this interesting practical.
