The Ebola virus causes an acute, serious illness which is often fatal if untreated. Ebola virus disease (EVD) first appeared in 1976 in 2 simultaneous outbreaks, one in Nzara, Sudan, and the other in Yambuku, Democratic Republic of Congo. The latter occurred in a village near the Ebola River, from which the disease takes its name. Today scientists are working towards the creation of a vaccine against this lethal virus and the infectious disease it causes
What is Disease?
Introducing Infectious Diseases and the Pathogens!
Remember diseases can be classified into two main categories - infectious and non-infectious. In this section we are going to focus on Infectious Diseases. Infectious Diseases are caused by pathogens. The main types of pathogens are bacteria, viruses, protozoans, fungi, macroparasites and prions. They are parasites that live in or on another organism known as the host AND have a harmful effect on the host. Some pathogens are large enough to seen without a microscope such as tapeworms and head lice. Most pathogens are tiny and cannot be seen without a microscope. When you catch a disease from another person, it is the pathogen that invades your body.
Complete the worksheet "Introducing the Pathogens". You can use your Core Science 5 Chapter 2: Medical Science. If you would like more information on the pathogens view the ClickView Introducing the Pathogens and complete the review questions after viewing to deepen your understanding.

c) Non-Infectious Diseases - You can't catch us!!
Poster due: Thursday 3rd March
Poster due: Thursday 3rd March
Here is the PowerPoint file needed to create your poster "Non-Infectious Diseases" . You will need to open this file on a computer using PowerPoint and you can make as many changes as needed. Many students last year completed this task over two pages rather than one. Make sure you follow the instructions on making an A3 poster using PowerPoint
Interesting Science - Why are Bees around the World Disappearing?
You have probably heard that bees are disappearing at an alarming rate. Currently Australia is one of the only places in the world with a healthy population of bees. SO what is happpening to bees???? What can we do to save them??? The answer is VERY simple..... watch this video! Summary - Honeybees have thrived for 50 million years, each colony 40 to 50,000 individuals coordinated in amazing harmony. So why, seven years ago, did colonies start dying en masse? Marla Spivak reveals four reasons which are interacting with tragic consequences. This is not simply a problem because bees pollinate a third of the world’s crops. Could this incredible species be holding up a mirror for us? How much longer can the bees survive? Bees are dying at a rate of 30% of the world's population every year. The solution starts with our help.... |
