Week+2+Measuring+&+Magnification

=**Weekly Content**= This week we are continuing to learn about the importance of microscopes in biology. We will learn about the different types of microscopes and their application by completing the Web quest below during class.



This video is a bit old (check out the 80's outfits) but it provides a very good description of how an electron microscope works. media type="youtube" key="lrXMIghANbg" height="315" width="420" align="center"

=Practical= Microscopes allow scientists to view specimens at a magnification much greater that of the human eye. So have you ever wondered how to measure the size of something that may be magnified several hundred times?

=Reading and Other Media= Reports in the news this week announced the arrival of a new hyperbaric chamber at the Sydney Prince of Wales hospital. These chambers are used to provide Hyperbaric Oxygen Therapy (HBOT) by fuelling the body at a cellular level with high amounts of oxygen. The cells in your body perform at an optimum level when they are in an oxygen rich environment which can be used to help repair cells damaged by cancer, surgery, or other causes.

=Homework= 1. Complete the comparison of microscopes worksheet (available above in the weekly content). 2. Complete all of the questions from the practicals. Come and ask if you have any questions at all.

=Student Content= Got something you would like to add? A video, webpage, or comment you would like to make. Go for it!
