Scientific Report: Preventing Rust

Title: Preventing Rust           Class: 5/6C           Date: ?????




Aim: To find the most efficient and effective way of preventing rust.



  • Copper Ribbon x3
  • Beaker 600ml x4
  • Vinegar (300ml)
  • Wax
  • PVA Glue
  • Bunsen Burner (Help Needed)
  • Tripod
  • Gauze Mat



  1. Get materials.
  2. Pour vinegar into one beaker.
  3. Place all copper ribbons in vinegar.
  4. Place tripod on top of Bunsen burner and place the gauze mat on the tripod.
  5. Place wax in one beaker and place that beaker onto the gauze mat.
  6. Turn on Bunsen burner. (With help)
  7. Wait till wax melts.
  8. Turn off Bunsen burner. (With help)
  9. Put 1 copper ribbon into the molten wax and remove the molten wax beaker from Bunsen burner.
  10. Place another copper ribbon in empty beaker.
  11. Put PVA glue onto copper ribbon (Till covered)
  12. Leave both beaker next to each other.
  13. Place last ribbon in the last empty beaker.
  14. Then observe your results in 1-2 days.


Hypotheses: My prediction is that the wax will be the most effective but the glue will still be better than no way of prevention.



Air: Showing small signs of rust, no other reactions.

Glue: No rust, completely covered in glue and glue has not yet solidified

Wax: Wax has solidified, no rust yet and an air bubble has been trapped under the wax with the copper.


Air: Rusted completely, no other reactions

Glue: Has not rusted at all, has been successful.

Wax: Has rusted yet only in the area of the air bubble. Areas submerged in  wax completely unaffected

Conclusion: In conclusion the glue has been the only way to succeed but the wax has improved on the air and has only had a flaw exposed. Overall the experiment was successful.

Extreme Weather Project Reflection (Term 4 2014)

For my extreme weather project my partner was Lilli and our topic was floods.

Most of our research and information was generally found through prior knowledge. But on occasion we used the internet to pick up key details such as repair costs.

We used note taking on one – note yet, since most of our information was what we knew prior to the assignment not much note taking was used.

I think my partner (Lilli) and I worked well together. We both pulled out weight and regularly met to assign tasks to do in our free time. Both of us always completed our tasks on time and ended up having our project done early.

The format we used was a PowerPoint. We chose this because we had more experience using the program compared to other options.

The tasks I did were creating the PowerPoint (half with the help of my partner), answering half the questions, helping create the information and content and completing research.

Rust (Science Prac Report 2014)

Aim: To see if certain conditions can affect how fast something rusts.

Materials: Steel wool, eight beakers, vinegar, oil, salt water and water.

Method: Fill 4 beakers with vinegar, 1 beaker with 150mls of oil, another with 150mls of salt water and the last beaker must be filled with 150mls of regular water one beaker must be empty. Then take 4 equal pieces of steel wool and place them in the vinegar. This will remove the irons protective coating. Then after 3 minutes take the steel wool out. After that put each piece of steel wool into one beaker without vinegar inside it including the empty one. After you’ve completed that you should wait 1-2 days and check your results.

Results: The steel wool in air rusted the most. The steel wool in water rusted a bit and also changed its volume to get bigger. The steel wool in the salt water rusted and changed color. And the steel wool in the oil broke down and some of it was resting on the top, it also rusted the least.

Discussion: The steel wool in the air rusted the most because it was exposed the most to oxygen. Combining iron and oxygen creates iron-oxide which is rust. The steel wool in the water was rusty because water is a combination of hydrogen and oxygen but it rusted less then the air because more oxygen is in the air than the water. The steel wool in the salt water had the the same reaction as the water but salt water tends to cause rust more quickly than normal water because salt is present. And the steel wool in  the oil rusted the least because water doesn’t mix with oil and the oil kept oxygen out.

Conclusion: The steel wool in the air rusted the most, the steel wool in the salt water rusted the second most, the steel wool in the water rusted the third most and the steel wool in the oil rusted the least.

A Day in the Life of a Rotting Corpse

A rotting corpse has a tight schedule of things to do. First it will rot and smell bad because it is slowly decomposing, rotting corpses will do this every day for 24 hours. Firstly a rotting corpse will rest lifelessly in a coffin or in the earth. Then a rotting corpse will rest lifelessly in a coffin or in the earth. After that on a very rare occassion a corpse will come out of its grave and starts eating peoples brains people call this a zombie. After a while a rotting corpse will rest lifelessly in a coffin or in the earth. Then the cycle will continue until the corpse rots away.

The Science of Bacteria

Bacteria is used as a way of fueling the sewer plant and is used for even more bizarre things! Did you know that bacteria is almost everywhere and is probably on you right now! The only places bacteria doesn’t inhabit are: soil, water, acidic hot springs, radioactive waste and under the earths crust. Bacteria is needed for you to survive by dissolving  compounds into energy. It thrives in deep parts of the world like trenches and even lives inside you. When you poo your poo goes through a sewer pipe and enters a sewer plant  and is processed but the interesting part is that it the poo is transferred and is turned into bio solid which powers the sewer plant. But the bio solid is formed by the bacteria changing the poo so in a way the poo and bacteria powers the plant that processes the poo. Bacteria was even one of the first lifeforms to walk the earth. Bacteria is sometimes beneficial to your body bacteria like Bifidobacterium animalis is good because it aids the digestive system but sometime bacteria can be bad such as Salmonella Typhi this sort of bacteria can kill but not all harmful bacterias kill.

Explanation: The Lifecycle of Stars

This term at MPPS the year 3/4s wrote explantations. They needed to come up with a question and write about it these explantations needed to have features such as: cause and effect, tier 3 words, authors purpose needs to be to teach, and it needs to have a impersonal and serious voice these are some of the features. Heres my explantation on the lifecycle of stars.

Explanation: The lifecycle of stars

Have you ever been gazing up at the stars on a quiet night and asked yourself, “Whether they would stay there forever?” Stars are always above us in space and their life cycle is very different compared to ours. It even uses other stars that explode!

The lifecycle of a star starts with a nebula. A nebula is a cloud of hydrogen, helium and cosmic dust. Nebula is also the Latin word for cloud. When a nebula is affected by an explosion it breaks into smaller swirling clouds. At the centre of these clouds is a protostar. A protostar hasn’t developed its surface properly and doesn’t emit light and heat in the same way. The protostar will get hotter the protostar does this to develop and burn its hydrogen so it can survive and eventually it ignites and a new star is born!


The nebula leads to smaller swirling clouds and the protostars and the new star is made

After the star is born it will continue to burn hydrogen for several billions of years the smaller the star the longer it live. As it burns it gets bigger until it gets so big it turns into a red giant. Red giants are enormous and have a huge surface area. They’re mostly made up of gas, and as the name suggests they’re bright red.

When an Explosion affects a red giant the force blows off a layer of its gas which makes nebulas this process continues. Then the red giant turns into a smaller planetary nebula, this is a smaller star enveloped in gas.


 Stars burn hydrogen and then turn into red giants that lose gas to become planetary nebulas

Once the planetary nebula loses most of its gas it turns a bright white and is very small and dwarfish. This stage in the life cycle is called a white dwarf the white dwarf will continue to burn its hydrogen until it runs out.

After a star loses all its hydrogen it will explode! Effecting heaps of stars across the solar system. This explosion is called a supernova and it can last several days. It also has multiple types such as the pulsar which consists of several flashes because it has two poles of light with a blue core we see it as it rotates so it’s not actually flashing but your eyes will see this. This is similar to something called the munker white illusion if you type that into your search engine you and click on images you can see an illusion of colours this is similar to what we see as the pulsar rotates.



Different types of supernovas

Soon after a supernova dies down the star usually dies and is gone. But heavy’s stars shrink until they’re no bigger than a grain of sand instead of dying. But it still has a gravitational pull its gravity is so strong it has the ability to suck in light from a few kilometres away! This is the last stage in the life of a star and this does not happen to all stars it’s called a black hole. Eventually the black holes mass gets so big and it will collapse on itself and die. Then the life cycle continues…

The science of Di Cats (Felis Catus)

Did you know that cat’s spend 85% of there day doing nothing by nothing I mean eating, drinking, pooing, sleeping and generaly being lazy. There nose also has a print just like a human fingerprint. And that catnip is almost like a drug for them because 1 of its natural oils enters the cats system and acts like cat phermone And this will happen in around 80% of cats.  Since cats us scent to communicate when you pat a cat It puts its tail up this means it wants you to smell it’s behind This resembles a hug or hand shake for cats and spread they withe rub against you to put its signature scent on you and otherwise claim you. Some people say cats have night vision this is in fact not true they may have a additional feature in there eye that reflects light out so they can see in dim lights but in complete dark they can see no better then we can. Cats bury there poo not only to not attract predators but to show they are with a dominate cat this’s your cats way of recognising you as dominate. When a cat is angry it will hiss and puff up it’s fur it hiss’s to intimidate other cats and show its teeth. String is a cat toy but it can seriously hurt cats if they catch it between its teeth and eat it this is replaced by laser pointer dots which are very safe as they’re completely harmless and will not blind cats. Cats play because it improves there hunting and fighting skills they may also playfight to reduce there fear of attacking other animals
