Welcome back to all students over the coming few days. The website has been very quiet over the summer, but will be updated everyday for the coming school year - so check back regularly. I am hoping to introduce many new initiatives for the website this year - including competitions for students, updating this blog page much more regularly with exciting updates and discoveries in the world of science and updating the biology notes - making them better (with animations and interactive content in the not-too-distant future!)
 
 
Best of luck to all biology students in tomorrow's exam!
Last minute revision hints:
  • Go over important definitions - especially those in Unit 2: the study of life.
  • Go over important schematic diagrams - such as those describing photosynthesis, respiration, nutrient recycling, menstrual cycle, hormonal negative feedback, cell cycle, binary fission, endospore formation, and reproduction in Rhizopus.
  • Revise important experiments (especially the effect of pH on enzyme activity - which has never been examined!). Important experiments include all the enzyme experiments (four experiments); DNA isolation, dissection of the heart; production of alcohol using yeast; and ecology activities.
  • Finally, take a quick look over the mind maps at the end of each chapter of Bio!!!!

In science class today, second year students had to design a poster showing the effects of global warming.

In first place was a poster showing the Statue of Liberty, the Millenium spire and the Eiffel tower before and after a dramatic sea level rise.

Picture
In second place was a poster showing a polar bear on a very small ice berg surrounding by sea water.

And in third place, a poster showing the Earth, in the form of an icecream cone, being turned upside down.

 
 
Students in 5th year managed to get very nice results in their experiment to determine the optimum pH for celery catalase activity.
 
 
Have a look at this amazing 4 minute video on how the reintroduction of wolves into Yellowstone National Park in California has had a phenomenal effect on the whole ecosystem - including chnaging the direction of the river!

Charles Darwin was born on this day in 1809. Do you have any evolution questions?
