Earth Science Week – Hong Kong Geopark

Elly and volcano

Today we had an exciting opportunity to link up with Ng Young C. Y., a Hong Kong national who is a driving force behind the establishment of the Hong Kong Geopark. He is an expeerienced presenter, member of and advisor to  numerous committees and boards of management for conservation of geologically significant areas. Young had lots of information about the difficulties establishing a geopark in a metropoliton area, wonderful images of the park and it’s significant features and ways they market the geopark using appropriately named dishes of food (such as the tempura prawn volcano!).

Students learnt about the igneous rocks that we passed around, drew a labelled cross-section of a volcano and were able to ask questions about the geology of the park. We also look forward to tomorrow’s presentation by Ian Lewis about caves, sink holes, fossils, volcanoes and bats. Ian is an ex-teacher, geologist and member of the Kanawinka Global Geopark committee. He was born on the side of a volcano, loves caves and diving and will be sharing lots of his photos and knowledge about all things volcanic!

Bats – mammals with the power of flight!

How and why did bats start to fly? One of the great mysteries of vertebrate evolution is a step closer to being solved, thanks to a little aerodynamic analysis. You may have seen the recent David Attenborough series “Life of Mammals”, which featured the sometimes maligned mammal and described how it’s ancestors took to flight to take advantage of the gap in the ‘airborne insectivores at night’ niche. Now a scientist  at University of California, Kristin Bishop, has used new aerodynamic analysis to study the difference between gliding and flapping flight. It’s all a matter of wing ratio and drag, she found.
