The process of rusting is when H2O meets metal. When metal, hydrogen and oxygen react together, a chemical reaction happens and it then forms something called rust. When iron and oxygen meet, they form iron oxide. When the rusting process happens, the metal becomes weak because their bonds are broken by the reaction. You can tell when rust forms on metals because it is a reddish-brown colour and can be broken easily. Some metals will rust after time and some will take longer than others. There are ways to prevent rust, like covering the metal in something protective, like paint.
Dr Wilfrid Derome was born in Napierville, Canada 1877. He was a toxicologist, ballistics, biologist, graphologist, judicial and forensic photographer and had two occupations- a doctor and a scientist. He was the founder of the first Forensic science laboratory in North America and directed it until his death in 1931 at the age of 54 He died of uremia. The laboratory contributes to improving scientific methods. The laboratory he founded is called Laboratoire des Sciences Judiciaires et de Médecine Légale.
In 1898 he received the Bachelor of Arts and won the French Hall of Fame in 2011 even though he was dead. There is now an award called the Derome Award and was first established and awarded to James Alexander Churchman in 1991. The award is presented to Pioneers of Forensic scientists every year and was named in honour of Dr Wilfrid Derome who was a pioneer himself.
In his career, he was the associate editor of the American Journal Police Science and added two articles in 1930 and helped solve the Delrome murder in 1922 and the Hochelaga Bank Robbery in 1924. He became the only accredited physician officially by the Government of Quebec for analysis and expertise to the government.
Dr Derome studied at the College of Montreal, Sainte-Marie College and Joliette Seminary. At the University of Paris he studied Legal Medicine and got a doctorate of medicine from the University Laval in Montreal.
Wilfrid invented the microspherometer, which can raise marks left on bullets fired from a gun to identify things like the type of firearm it was fired from. He became the first expert in North America to tell how much alcohol is in someone’s blood and do alcohol tests used as evidence in trial. Dr Derome also invented the technique of ball rolling or bullet rolling. The technique was to roll a ball on carbon paper or tin and find dent and scratches on it.

My name is Bryn and it term 3 the 5/6s did a project about exploration. Bailey, Jack and I chose to investigate Dr John O’Sullivan because we were interested in what he did and wanted to know more about him and what he discovered or invented to assist us with our lives.
Three facts I found interesting and surprising:
I found it surprising that John O’Sullivan improved the wireless LAN, something that we all use every day. He made it quicker and faster and how it affected us in our everyday life. Now wireless is more reliable and gets thing done quickly.
I found it interesting that out in W.A there are hundreds of ASKAPs (Australian Square Kilometre Array Pathfinder) spread out about 1K apart from each other so they detect disturbances and report them to CISIRO so they can prepare for whatever natural disaster will hit and save lives of many people.
I found it interesting about how many projects John O’Sullivan has been involved in and the changes he has made to our everyday lives. He has also lead projects too, and has taken a big part in the improvement of the Wireless LAN and put in a big effort towards the ASKAP.
Two understandings I now have:
I now understand what the ASKAP stands for and what it is and does. I also found out how many there are out in W.A and that they can save our lives by detecting stuff like cyclones and earthquakes. They can also collect data by taking photos to help with research.
I now understand who John O’Sullivan is and how he contributed in the field of science and what he did to help us and win the prime ministers science award in 2009. I also understand how he helped in CISIRO to make the ASAKP and improve the Wireless LAN.
One wondering I still have is:
Did John O’Sullivan do anything else in science apart from LAN and ASKAP because I’m still really interested in his work and life.
What were the most important things I learnt?
The most important things I learnt were how his improvement of the Wireless LAN helped us a lot with our life like researching stuff on the internet is now much faster to respond. I also learned how he invented the ASKAP.
How did I learn it?
I learnt it by researching websites about him and converting the text into my own words so that it was easier for me to get a better understanding of what he did. I also learnt it by asking questions to drive and assist me with my research.
What am I going to do with what I have learnt?
I am going to keep it in my mind as knowledge and use it whenever I need to too help me with things. I am also going to keep my knowledge on how to use and operate Prezi so I can easily use it next time.
Finally a concluding statement where you share your overall thoughts and feelings about your project, the work you did, what you learnt and how it was working with your team.
We would like if Bailey, Bryn and Jack would be able to work in a group of three because we all believe that we will be able to work together in a way that will make the outcome of the project be panoply of all the tasks that will be thrown at us. we think it will be a good learning opportunity for all of us to learn from each other as the project rolls on. This project will be a plethora of new and exciting things that we will be able to discover/learn during this project. We all think that we will share the work load equally so no one will be left out of the project and everyone will learn from it.
We would like to work on the Australian explorer John O’ Sullivan. He studies in the area of astronomy. He will have a lot of new information for all of us to learn about. We chose to work on him because we are all interested in the topic of astronomy and he was the first one we found on the topic of astronomy. He has been working in astronomy for 30 years so he is very experienced and should have a lot of information for us to learn about and then present it.
How were going to present it.
We have decided to use the program called museum box to present our project because it is set out in a way that will help everyone learn from it. And it is creative and will show your information in a creative way that helps everybody enjoy the presentation. It can hold a lot information so we can put as much as we learned into our presentation so expect a lot of detailed information if we are able to use museum box to present our project.
Bailey, Bryn and Jack
This term we were all put in groups and asked to do projects on the systems of the human body, the systems were Muscular system, endocrine system, lymphatic system, circulatory system, digestive system, skeletal system, urinary system, nervous system and respiratory system. The requirements were to type up a word document with the following headings: Description, history, future, care and problems. We were also had to make a 3D working model on the system we were assigned to do, work as a team, co-operate and make a power point in a certain amount of time. On each presentation we were asked to take notes about each system.
Muscular System: Muscles are very important in the body because they move. Cardiac muscle is a muscle in the heart. Muscles can vary in size throughout the body. Muscles contract and relax when you move.
Endocrine System: Hormones send messages throughout the body. A target cell can only be a target cell if it has a receptor. There are many problems in the endocrine system. The endocrine system consists of lots of different hormones. Claude Bernard was the first ever person to state the description of the endocrine system.
Lymphatic system: The lymphatic system was discovered by Dr Gaspard Asseli in 1662. The lymphatic system is a network of tissues and different organs like tonsils. You can easily get rid of tonsils if they get too big for you. If you laugh and meditate you are taking care of the lymphatic system. All the lymph nodes inside your body are green.
Circulatory system: The heart is a vital muscle that pumps blood through your body. William Harvey first described the circulatory system in 1616. If there is a blockage in the coronary arteries it causes a heart attack. Blood is made of red and white blood cells. Marrow in bones makes white blood cells. Veins are less flexible than arteries.
Digestive system: a diesis the pancreas can have is diabetes. The small intestine is 6 meters long which is longer than the large intestine. The large intestine gathers vitamins. The large intestine takes about 16 hours to digest food. Eat good food like vegetables and grains to take care of the digestive system. Saliva makes it easier for food to go down the oesophagus.
Skeletal system: There are 206 bones in an adults body. You can take care of your bones by drinking/eating calcium and exercising which makes the joints move more freely. They used to use bones for useful things such as handles for knives, forks and spoons they also used them for flutes.
Urinary System: Urine is a clear yellow substance containing unwanted wast. The kidneys are red and brown. The bladder contains the urine after it’s been through the kidneys. Roman spies used urine as invisible ink. You can live without one kidney because you only need one.
Nervous system: The nervous system includes the brain, spinal cord and nerve cells. You couldn’t live without the nervous system. If you damage your spine you will feel lots of agonizing pain. Epilepsy is a diesis that causes sudden jolts and staring blankly.
Respiratory system: Lungs are a red and brown organ that helps with breathing. If you breathe in dirty air the respiratory system filters out the bad molecules. Lung cancer is cause by smoking because of all the tar. Scientists are thinking about making replacement lungs with 3D printers. Asthma is caused by the trachea blocking up.
I learnt a lot during all of these presentations they all had lots of good information and good 3D models. While taking these notes I have built on my knowledge of the human body and can now give facts about each system with no hesitation at all. I also think I worked well as a group member and I feel we had a good amount of information and a good demonstration of the hinge joint for our 3D model.
•Make a list of some of the important thinks you learnt:
One of the important things I learn was how to stay on task and gather information. Before I used to get distracted by other things around me that are going on but now I have the ability to stay on task when needed and gather good information.
•What can you do now that you couldn’t do before? :
I can now use a very helpful website with lots of information that is very helpful called Microsoft Encarta for kids. Before I didn’t know this website but it is very reliable and has very good information not like some other sites that I have been on like Wikipedia.
•What or who helped me? :
My dad helped me by find some good web helpful sites to read information off and were reliable, he also kept me working when I thought I had finished. Microsoft Encarta also helped me with lots and lots of the information that I had gathered because I knew it was reliable.
The estimated population of Pakistan is 176,745,360. The population density of Pakistan is 215 people per square km and that is a lot more crowded than Australia! Some instrument the Muslim’s invented the sitar (a guitar like instrument) and the tabla (a small pair of hand drums). Pakistani rupee is the type of money used in Pakistan. One Australian dollar is equal to 103 Rs.
I understand that Pakistan has different religions to Australia and they worship different gods and different traditions and festivals. Pakistan and Australia have very different land spaces, Pakistan is very densely populated and Australia is not very crowded at all.
I wonder how Pakistan will evolve over the years and if there population will grow in size and get very dense or get smaller and easier to get around.
