The first lesson after the AS exams was a surprise to the AS biology students as they were to be volunteers in a research project for the University of Hertfordshire, Pharmacology Department. The bottom line was it didn’t hurt! The top line was it was fun and, most importantly, the findings could be useful in the development of drugs to prevent conditions of the skin. The PhD student who conducted the research demonstrated the scientific skills which we teach, such as fair testing, and explained how the method was conducted so that the results would be valid and reliable. Science was definitely in action and we were part of it.
Trip to the Natural History Museum
The students looked at the pentadactyl limb, researched interesting facts about the human body and looked at ‘science in action’ at the Cocoon.
The pentadactyl limb has evolved in thousands of different ways due to the different uses it has depending on the animal it is attached too. The pentadactyl limb exists in animals from dolphin to horse to bat, animals which each use the same limb in a completely different way. Every pentadactyl limb has the same base structure of five digits but they all look very different and also do very different things. This is all because of evolution.
The pentadactyl limb has 5 digits on the hand and foot. It also has a specific pattern of bones.
The structure of a human arm includes a bone between the shoulder and the elbow called the humerus. Below the elbow are 2 other bones, the radius and the ulna, followed by a set of wrist bones and then the 5-digit fingers and toes. This is an example of a pentadactyl limb.
The pentadactyl limb is common to humans, other mammals (although whales and dolphins have lost their hind limbs), birds, dinosaurs, and other reptiles and amphibians.
