Metals (Changing copper coin to gold)(Alloys).

Aim: Turing a copper coin into silver and gold.

Method:
1) Clean the copper coin with the wire wool.

2) Add five grams of zinc powder into the water ( Now you have made the solution).


3) Now turn on the bunsen burner to boil the solution.


4) Once the solutions are boiling then add the copper coin.


5) Once the copper coin turns silver lift it out the glass beaker.


6) Now put the silver coin in some water to cool down.


7) Take the coin out of the water and dab it dry with a tissue.


8) Now take the coin using the beaker tongs and put it on the flame of the bunsen burner.

9)  flipping it occasionally

Equipment: Wire wool, Five grams of zinc powder,  beaker, Bunsen burner, gauze mat, tripod, tissue, beaker tongs. 

Result: This experiment turned out great this is what my coin turned out like:

Discussion:
An alloy is a mixture of two or more elements, one or more of which is a metal. Alloys often have properties that are different from the metals they contain. This makes them more useful than the pure metals alone. For example, alloys are often harder than the metal they contain. Steel is an alloy of iron and carbon. It is used to make many things such as cars, ships, bridges, and building frames. Steel is harder, stronger and more flexible than iron and doesn't corrode (rust) as quickly as iron. Other examples of Alloys are brass, bronze, pewter, cast and wrought iron, coin metals, and solder. Alloys have special properties, They are more conductive to heat or electricity, less prone to rust or corrosion. Alloys are made by melting metals, mixing them while they are soluble to form a solution, Then leave them to cool and turn into a solid again. There are two different alloys, one is called substitution alloys and the other is called interstitial alloys. In substitution alloys, the atoms of the original metal are literally replaced with atoms that have roughly the same size from another material. Brass, for example, is an example of a substitution alloy of copper and zinc. Aluminum alloys contain next to no iron and without any iron, the alloys cant actually rust. It does however oxidize. When the alloy is exposed to water, a film of aluminum oxide forms quickly on the surface. The oxide layer is resistant to further corrosion and protects the metal. 



Substitution alloy and Interstitial alloy
Substitution alloys are when you replace one atom with another that is of the same size as the photo above shows whereas Interstitial alloys are where the other atom occupies the spaces in between the former metal atoms.

Year 10 (Acids and Bases) (Making Salt)

Aim:
To produce copper sulfate salt by reacting copper oxide with an acid.

Equipment:
Copper oxide powder, dilute (0.5 mol L-1) Sulfuric acid, 50mL measuring cylinder, two 100 mL beakers, Bunsen burner, tripod, gauze mat, funnel, filter paper, thermometer, spatula, evaporating basin, stirring rod.

Method:

Evaluation:
My experiment was a bust it was going just fine until a classmate decided that she should pick it up, She dropped it. So I do not have my results but I do have those of another few groups they ended with tiny blue crystals, But they were all a little different.

Here are two of them.
Discussion:
In class we have been learning about acids and bases. We learnt how Chemical equations worked.
        CuO         +       H2SO4        ➝            CuS04          +     H20
Copper Oxide  +    Sulfuric acid   ➝     Copper Sulfate    +    Water 
We have also been learning about positive and negative charges (also known as Ions) Here Is a photo that goes more in depth about what an Ion is and how they works. 

Year 10 Atomic Science (Burning magnesium)

Aim? I am investigating whether or not burning magnesium makes it heavier.

Hypothesis? I think the magnesium will become lighter because it will become ash instead of a solid, I also think some of the ash will get stuck on the tongs and be blown away with the lightest wind.

Equipment:
Heat mat, Bunsen burner, Scissor Tongs, Beakers, Scales, Magnesium, Safety glasses, Lighter.

Method:

1. Gather and set up all your equipment.
2. Weigh a strip 

Safety: Glasses are needed. long hair must be tied back. Flame killed as soon as done with it.

Evaluation: My experiment was some what a failure. Instead of weighing your magnesium on paper I highly suggest that you measure it in a beaker. I say this because my piece of paper got burnt when i put the magnesium down on it. 

Discussion:

What i learnt from the Scipad?

Stupid boomerang.

In wood tech, we were told to make a boomerang.
I feel this project was a waste of time that Mr made us so because he didn't have anything else to give us to do. Honestly, the lesson could have been planned better with a better task that would actually get us to want to do it. My boomerang was done well but a waste of wood so I chucked it. Next time please set up a better lesson, Thank you.

manufacturing a metal drill gauge

At school in metal tech. We have been making drill gauges, used to find the size of drills. I would have a photo of my drill gauge on here but unfortunately, I took it home and dumped it before I knew we were doing an instructional blog.

Although this is what a proper drill gauge would look like.
To make the drill gauge we used these tools.

1. Metal bar 20mm W 100mm L 5mm T

2. 300mm stainless steel ruler

3 Scriber.

What is a Scriber?
A scriber is a hand tool used in metalworking to mark lines on workpieces, prior to machining. The process of using a scriber is called scribing and is just part of the process of marking out. 

4 Engineers Square.

What are engineers square?
An engineer's square is a tool used in metalworking and woodworking. It is. very similar to a try square in appearance and use, and is mainly used to check a workpiece is 'square', (that is, two sides are at 90 degrees to one another).

5 Buffer.

What is a buffer?
The Polishing Machine (also called the Buffing Machine) is used to polish soft metals including copper and brass as well as plastics such as perspex.

6 Drill press.

What is a drill press?\
Drill press, also called Drilling Machine, device for producing holes in hard substances. The drill is held in a rotating spindle and is fed into the workpiece, which is usually clamped in a vise resting on a table.

7 Micrometer.

What is a micrometer?
a gauge that measures small distances or thicknesses between its two faces, one of which can be moved away from or towards the other by turning a screw with a fine thread.

8 Vernier caliper.

What is a vernier caliper?
A vernier caliper is a measuring device used to precisely measure linear dimensions. It is a very useful tool to use when measuring the diameter of a round objects like cylinders because the measuring jaws can be secured on either side of the circumference.

9 Emery cloth.

What is emery cloth?

Description

Emery cloth is a type of coated abrasive that has emery glued to a cloth backing. It is used for hand metalworking. It may be sold in sheets or in narrow rolls.


10 Center punch.

What is a center punch?
A tool consisting of a metal rod with a conical point for making an indentation, to allow a drill to make a hole at the same spot without slipping.


11 Hammer.

12 Odd leg caliber.

What is an odd leg caliper?
a caliper having the points of its legs bent in the same direction for measurements on stepped surfaces or similar surfaces

My drill gauge was done well Although I could have marked my work out a little better. I found marking it out to honestly be the hardest part of making my drill gauge because im not a very precise person. I overcame this by asking for help and seeing how other people were doing. I learned ho to center punch on the line.

Method of making this drill gauge is pretty simple. You clean up your 100x20x5 bar, Mark out through the middle of the bar and space out where your drill holes will be. Drill the holes the size you are doing. Clean the bar again, buffer it. Then you should be done.

This is my own online created drill gauge.

If I'm being honest, I did have a much better design that I put two lessons worth of time into. I could however not find it so I made a quick 5 minute one. This way I can at least get a score for it.
Here is a picture of my original design that was a failure due to me not setting the printer up properly. However, if I was to attempt it again I would know how to do it easily this time because I have learned from my past mistakes.

My Zootopia Essay.

A character who changed during the film Zootopia is Judy.

Judy changed from one thing to another to back where she started but she was just a little bit better off. Judy changed from a dumb bunny who thought anyone could be whatever they wanted to a smart bunny who knew that anyone could be anything with hard work.

Judy was a small bunny who believed that anyone could be anything. That even though she was small and weak she still believed she could become a cop. We see this nearer to the start of the film when Judy is on stage and claims she is going to make the world a better place she is gonna be a police officer. The lightning to me in this scene was a little bit weird, But how I saw it was there was a bit of bright lighting behind Judy to show her passion to be a cop and that she believed she could do it. But then the scene also had dark lighting around it which to me meant that Judy was the only one that believed and that the rest of the crowd were all in disbelief. The Audio in this scene didn't make a lot of sense to me either but I personally thought it mad for a cool build up.

Judy goes through a lot during the film. She gets a lot of crap from people who stereotype her. During the film, Judy's idea of zootopia the perfect place where anyone can be anything gets torn down. She realizes even in this amazing place there is still a lot of wrongs. We see this nearer to the middle of the film when she quits the ZPD. The lighting in this scene is very plain it's very basic and doesn't tell me a lot about the scene at all. However, even though there is no audio in this scene it gives us a sort of sad sympathetic feeling. What makes this scene so good and what makes us feel for Judy as a character is that lack of audio.

Right, when the movie is wrapping up after Judy has solved the missing animal's case. Judy is happy again although there are always speed bumps she learns that anyone can be anything they just need to work hard to get to where they wanna be. None the less Judy is proud of what she has done and where she has gotten. The lighting is these last few scenes is bright and colourful based on just that alone it makes us the audience happy. And were in this good mood but then the audio kicks in and it's so upbeat and joyful. Which makes us happy and really feel the emotion in that scene.

I didn't know how to write up my conclusion apologies.

Will write a conclusion when I have a better understanding of how to write it.
