Why does magnesium burn in water - Science

Magnesium. It is a metal that is used in many things that range from cars to vaccines. It is well known for being very brightly visible when burning. But another thing it can do is burn underwater. I am here to investigate how.

Experiment

Aim: To find out how Magnesium burns in water

Equipment: Magnesium Strips, Bunsen Burner, Beaker

Method:

1. Light the Bunsen Burner
2. Light Magnesium in the bunsen burner
3. Once alight, drop magnesium in the water

Observations: When magnesium was on fire, it set off its signature white glow. Once dropped in the water, the magnesium lasted about 0.5 seconds before being put out. I tried many times but the same thing happened every time

Conclusion: Magnesium does burn in water sometimes, but not this time for me

I have seen some videos on this and they all worked in different ways. One was a guy spraying water on to it, another was some guy doing it similarly to mine using a beaker, however, he only held it at a high level in the water, about surface level. This allowed oxygen to get to it better and allow it to keep burning. In my experiment I just dropped it in, disallowing this to happen and ultimately it went out.

So obviously magnesium only burns in the water when held at a certain level and allowed oxygen.

I thought this until I saw another video
In the video, the person drops the magnesium in the water in a similar way to me, but it continued to burn in the water. This has perplexed me to as why mine did not work. The way magnesium can burn in water is when magnesium burns so hot that it is able to separate water molecules. Water is made up of Hydrogen and Oxygen. Hydrogen is flammable and Oxygen is basically fire, so you get the picture. 

Thanks to this random person I found on the internet

This begs the question. If magnesium burns so hot that it can literally break up water, does the temperature of the water depend on if it will work? The answer is no as the average temperature of cold tap water (the type I used) is around 7 degrees Celcius. Magnesium burns at about 2200 degrees Celcius. There is a temperature difference of 2193 degrees Celcius. That's hotter than the surface temperature of Venus, the hottest planet in the solar system.  There is a possibility that the chlorine in the water could've affected the way the experiment went. Chlorine is not flammable but I doubt that there is not enough chlorine in the water supply to stop it from happening. But for now that seems like the most likely cause, and when we stop getting chlorine in the water I'll have to try it again and see. But until then, I'll have to do other experiments.

I had fun with this experiment and hope to get to do more in the future

Essay in english

In English, we are writing essays about book children of blood and bone.

Heres what I have so far

Children of Blood and Bone

Introduction

Different. This word is used a lot to describe people who are, well, different from you. But is it an excuse to wipe out nearly an entire race of people? Children of Blood and Bone discusses this idea throughout the whole book. Through the twists and turns that bring it together, the author, Tomi Adeyemi, uses different techniques. I will be talking about the methods and techniques the author uses such as the use of multiple perspectives, the way the novel is structured, and the use of symbolism.

Body 1

Zelie, Amari and Inan. These are the three main characters of the book. They are the characters that you see the points of view from. You spend a chapter in each character viewpoint and see what they are thinking at a certain point in time. The use of multiple perspectives allows the reader to see the progression of a character as they evolve throughout the book. You see that Amari and Inan have come from the same background, but because of the people they became friends with and revolved around, they had different ideas of what was good and bad. It also shows how those beliefs led them to different people, with Amari coming to Zelie, and with Inan struggling to find right from wrong, coming to Zelie and Amari, but ultimately choosing the opposing side. The use of multiple perspectives helps us understand how this switch to the opposing side affects the characters in the book.

Body 2

The structuring of the book also has an impact on the way that we see the events happen. Often when the book changes the character that we see the POV from, we see an event happen again. This happened notably when The trio ( Zelie, Amari and Zelie’s brother Tzain) did the sea battle in Ibeji when it was Zelie’s POV for the start of the battle when she tried to summon ghost people, then it switched to Amari’s POV and it restarted the battle and then got up to when Zelie successfully summoned ghost people. It then carried on the battle from Amari’s POV. This helped us understand the way characters were feeling and reacting in their heads at the exact same moment.

Body 3

Symbolism is another way we see the story get pieced together by the author. There a few things that symbolise something in the story, but they have major impacts on it. One of the ways something gets symbolised is a sênet pawn that Inan takes with him on his journey. It is similar to a chess piece and is used in a strategy game that Inan used to play with his father. He uses it as a sort of physical form of his father's teachings. He holds it when he needs to be reminded of what he is fighting for, to be a good king. This plays a major role in the book because when Inan figures out what his father is doing is wrong, he drops it and leaves it behind, symbolising that he is forgetting his father and moving on. It starts the path of him becoming maji, which he ultimately stops in its tracks, and takes a sword from his father and basically replacing the sênet pawn with the sword.

Conclusion

Children of Blood and Bone was a book written by Tomi Adeyemi and contained some unique technique that helped put the story together. These were the uses of Multiple perspectives, allowing us to see each person's POV to help us understand how they felt about the current event, the structuring of the book, with it going back to the same event so we could see how everyone felt about the thing at the same time, and the use of symbolism, seeing how people saw certain objects in the story and used them to help comprehend the events happening, as well as how the character changed with the idea for that object. That’s how I believe the techniques in Children of Blood and Bone affected the way the story happened. Do you think the same, you probably don’t. But hey, we’re all different.

Thanks for reading my essay, I hope you enjoyed

Corrosion - Science

In science, we are currently investigating corrosion and how other things can either speed up, slow down, or stall completely the corrosion process. We are currently doing an experiment where we have different iron nails and put them in different conditions. We have a nail in oil, a nail covered in nail polish in water, a nail with magnesium strips around it, in water,  a nail sitting in a mixture of water and Calcium Chloride, and a nail sitting in saltwater.

I'm not completely sure what is going to happen but here are some of my hypothesis

Nail in Saltwater: I think the nail will corrode a decent amount but not much

Nail in Oil: I don't think the nail will corrode

Nail covered in Nail polish: I don't think this nail corrode either

Nail with magnesium strips around it: I'm not sure what will happen

Nail in Calcium water: I think the nail will have been covered in gas from the reaction and not corrode

Observations:

Nail in Saltwater: The nail corroded/rusted not too much but a decent amount

Nail in Oil: The nail did not corrode at all

Nail covered in Nail Polish: The nail polish created a coating that stopped corrosion

Nail with magnesium strips: The strips rusted as well as the nail, probably had the most corrosion

Nail in Calcium water: The nail corroded slightly less than the nail in the salt water

Thank you for reading my blog, I had a lot of fun with this experiment and hope to do more like it
Please comment feedback as it helps my learning

The Stolen Generation

What is the stolen generation and what does this song say about

The Stolen Generation
The Stolen Generation was a large group of children that were taken from their families and sent away. These kids were half cast children. Half Cast meant mixed race between Aborigine and White. They were taken to schools and foster homes and taught to do jobs that fit into the new society

The Song
The song is Took The Children Away by Archie Roach. It is about how children were taken from their families and the lasting impact it had on those families
