We have started the new unit now and assignment was introduced. On today's lesson, Mr Ward told us how to calculate the velocity and did some example questions together. The formula for velocity is V= displacement/time. The units have to be minute and second. So if the times are in minutes or hours, we have to transform them in to seconds and killometres or centimeters into meters always. Mr Ward also told us the difference between velocity and speed, distance and displacement. They are similar to each other, except that velocity and displacement have the direction.

Simplified definition of Velocity and speed:
speed: distance travelled in a second
Velocity: distance travelled in a given direction in a second.

Simple definition of distance and displacement:

Speed = distance travelled in a second
Velocity = distance traveled in a given direction in a second

Definition of distance and displacement:

1. Displacement is the directed line segment between initial and final position of a moving body.
2.Distance is the total length of path traversed by the moving body irrespective of direction.

I missed some parts out of this blogging.

Mr Ward showed us how to put the buttons on the torch by extrude the draw from lateral plane. I'm not sure if I would remember that by the time I design my torch.

You need to have the barrel first, then we have to draw the button on the lateral plane then extrude it. Because we can't draw on the round suface of the barrel.

Mr Ward also showed us the model that is created by the new machine that builts up the things other than cutting off from the whole piece of the material like the old one did. He made iphone, chain, bolt(?screw?) and bangle and showed them to us.

toy block: I guess it was the simplest on among them all. All the measurement was noted not many new skills were required from what we learned.

Toy block extension: I had some difficulties on decision making with the measurement of this toy bleck. It was not mentioned in the textbook and my model looks bit different as the model in textbook.

Simple calculator Design: It was fine. Was not very hard and really satisfied with the ne duplication skill learnt from this project. I also liked the design of it some how it ressembles chocoloate.

Clock face project: All measurement were noted but still looked different even though I followed all the instruction correctly, twice and realized that it always looks different from the model on the textboo, they are thinner and smaller compare to what came out of my work.

Students accurately draw their own mobile phone: It would be much better if I had iphone because I have a galaxy note, I had to do the curves on the side which requires much more complicated skills, not just rounding the edges. I did all the details even the 20 dots on the speaker at the top of the screen. Only thing I couldn't do was the touch pen because I couldn't make the deciosin about the measurement.I did my phone 3 times because of that round edges and learnt to save for every successful steps.

Energy Drink bottle: the measurements in textbook was wrong but I could figure out the exact measurement as I go along.Because we did the waaterbottle last year it didn't find it hard very much. But I forgot how to revolve so it was great to learn it from this project.

Aluminum motorcycle wheel: We didn't have to do this project. But I reckoned that it will help me from get  better mark, I did this. Fortunately, I got enough time to finish everything that's listed on the task sheet. There was bit on difficult doing it because textbook didn't tell the measurements and skipped some steps. I learned mirror skill from the internet because it didn't really tell what to do to get the mirror command so I searched up in the internet and the result was well successful. I have different pattern on my wheel as the model from the textbook because it didn't say anything about drawing the wheel pattern.

Ball point pen: I borrowed the laptop and did some parts when I went to the basketball game when other grades were playing. I finished it during the weekend. Because I was stuck up with designing my phone, I did it before mobile phone and aluminum motor cycle wheel project.

On today's lesson I finally finished up everything just by the time and printed off them all. I accidentally printed them vertically that only takes up half of a paper. Some are printed in colour and some are not. At first, I printed pen assembly in colour but then it was hard to tell the division between the barrel and pen top so I printed off in colour for second time, horizontally. I gone trough the list just to make sure if I missed anything. I did the sony camera and motor cycle wheel that are optional. I might start the torch assignment from now on. Firstly do some research.

Our class exercise is due this friday. I almost finished them and just need to work some more on the motor cycle wheel. I had some trouble with accurately designing my galaxy because of its curve on the sides and the buttons would disappear if I round the edges too much. Mr Ward showed how to do solve that problem, but it looked a lot more complicated. He recommended me to keep them simple and because its due friday, I just decided to leave as it was. Then I moved on to my motor cycle wheel which never gets to be a valid profile and not allowing me to revolve it. So I just drew a new plane and fortunately, it worked. For the next lesson, I just need to revolve and do the rest of other stuffs, print off and all done! I think I may borrow laptop tomorrow afternoon to print off and do some more other words.

For the last lesson we had yesterday, Mr Ward gave us our assignment which we have to design a torch by the ProDesktop program and elaborate it. He showed us some A+ assignment for we to look at and when I had a look at them, I really did think that they both deserved A+. Especially when I was reading Hannah's, I really felt dizzy and couldn't even finish reading them. Frankly, when Mr Ward showed us Natalie McNamara's assignment, I thought I could do that as well, but when I had a look at Hannah's, I didn't think that I could possibly do that. (I'm not sure how to spell her name correctly, I hope I spelt it right.) Anyway, I will do my best for this assignment. As Mr Ward said in the class, he is really generous of time. The torch one is due week 2 next term and the first one is due by week 7 which is 2 weeks away, but I think I can do that in 2 weeks. Until now, I've done toy block, toy block extension and simple calculator design. I haven't done much but I have some plan so I wouldn't be worrying about it. I finished the calculator easily by one lesson and I will start on clock face project and car wheel and will work on Mobile phone during the weekend. Then I only have 3 more things to do for 2 weeks. I wasted about 2 or 3 lessons making that sony camera... :(

In today's lesson, I finished off my camera that I was working on and now I started with my phone. The techniques I need yo use are easy and I know how to do them. However, because I did them in a wrong order, I had to start it again for three times :( and at the end of the lesson, all I got was just a rectangular prism... I think I need to arrange the order before I start and that way, it will finish more earlier, I assume. When I'm finished with the phone, I will have a look what's on the sheet and will make some decisions then :)
