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.

Drill gauge.

What is a drill gauge?
A drill gauge is a tool used for identifying drill bits sizes. Made of heat treated heavy gage steel, machined and ground to tolerance. Hole sizes and decimal equivalents are permanently etched on the face.
