Today (The 18th of July) 5/6B went into the science lab to start conducting their fair test and rusting project. This is where we work in partners to try and find a way to prevent rusting. My partner and I are using 3 different types of oil.
We are using our knowledge of the 4 states of matter to conduct our experiments. My partner and I soaked 3 nails in the 3 different types of oil for just over 2 hours on then put them in salty water to see if the water had any effect.
The file POE has my prediction attached.

In term 2 the year 5/6 did their integrated unit on ‘Chemical Change’. So every week 2 scientists from GTAC came into Moonee Ponds Primary school to teach us about changing state, the 4 states of matter and much, much more! I enjoyed this unit very much and I believe I benefited well from it.
3 facts I learnt were:
I learnt many things but here are some of my favorites:
I learnt that the change from a gas to a liquid is called condensation. So say you just had a shower and you didn’t have the fan on so there is a lot of steam in the room. Then the steam hits the mirror and it will go from being hot to being cold. So it will turn into a liquid.
Another thing I learn’t was the interests of gas particles. Gas particles stay a fair way away from each other. They bounce of the walls and of each other when they come into contact with them. When the particles get heated up they move faster and when they get cooled down they move slower.
Another thing I learnt is that a solid can turn into a gas. That change is called sublimation.
2 understandings I now have:
I now understand that it is possible to go from a solid to a gas without going through the step of melting. I understand that that process is called sublimation. I first found sublimation quite weird and didn’t think it was possible but I found a example which explained everything: Dry Ice. Dry Ice does not melt when it is left in the sun, it turns into a gas.
Another understanding I know have is that scientists don’t use all 5 senses in the science lab. In the science lab you look to observe somethings like : color change, size change, shape change, ect. You use your ears to hear bubbling or loud noises or nothing at all. You use hands to feel if something has gone from smooth to rough or vice-verse. And you use your nose to waft of a potion or something similar. You don’t taste anything in case there are dangerous chemicals in it or such.
1 question I still have:
I would like to know if fish would be able to survive on the moon? I would like to know this because I believe there is hydrogen in outer space and in H2O there is Hydrogen and oxygen but we all know fish can’t breathe in oxygen. So I started to wonder weather they would be able to live in outer space and I would like to find out in the future.
What were the most important things I learnt were:
I think the most important things I learnt were the names of the changing state processes.(Melting, Freezing, Evaporation, Condensation and Sublimation) I believe these will help me throughout life so I can explain the changes of state I observe. This will help me in my P.O.E charts so I can have a good explanation at the end.
How did I learn it:
I learnt them by listening to the scientists from GTAC explain it to me and to see how they all worked. I found out that when you make pop-corn the kernel evaporates because the inside of the kernel is water. So when the kernel gets hot the water inside starts to boil until finally there is so much gas inside the kernel that it has to pop.
What am I going to do with what I learnt:
I am going to use this information in the future because I dream of becoming a scientist for GTAC. This is a dream because I quite enjoyed our science unit and would like to do more of it in the future.
Special thanks to:
I would like to say thanks to GTAC for sending us Maria, Jacinta and Chris to teach us about the 4 states of matter and changing state.

In grade 5/6 c we are doing a mini project on a forensic scientist and this is some information on Wilton Krogman that I collected…
I will be telling you about Wilton Krogman. He was born in June on the 28th in 1903. Wilton was a forensic anthropologist. For those of you that don’t know what a forensic anthropologist is then think of the TV show CSI other-wise known as crime scene investigations. What he did was use science to analyse bones to see who the bones belong too. He worked solving major crimes in the USA and set the standards for all the forensic investigators who follow in his footsteps. Not only did he work on modern crimes he was also involved in establishing and identifying ancient bones. He actually identified bones belonging to Egyptian pharaohs. For those of you that don’t know a pharaoh is a ruler of ancient Egypt. Wilton’s interest in forensic anthropology began when he was a child when he and his brother found the skeleton of a horse. As his interest grew he studied at the university of Chicago. After graduating he worked as a lab technician for Eliot Pess and was involved in the arrest of Al Capone, The world’s most famous gangster. He also thought at 2 different university’s and his findings are still used by forensic investigators throughout the world today. He died on the 4th of November 1987 as a 84 year old man. If you would like to expand on your knowledge internet explorer has many websites about Wilton Krogman. Thank you for listening I hope you learnt something new.
What are the 3 most important research skills I learnt?
I learnt many things this term during the my body my life project and got the chance to work with Angus and Jack. We worked together to do a presentation on the muscular system. But the 3 most important research skills I learnt were, to use recommended websites, use books and not just use the internet and to always take advice from other people.
How can I improve my group work skills?
To work better as a group and listen to every ones ideas without a interruption.
What is my goal for integrated?
My goal is to have better note taking skills so I can take notes a lot quicker.
