Criteria E- Evaluation

Evaluation

The assignment overall was decent and well-planned. It was fun on some times and confusing on others. The first step was choose what factor of the ger district we wanted to improve or choose what kind of a new invention we were going to invent. I would say that my assignment wasn’t all I thought it would be. When I first picked out my topic, I thought it was going to take forever to design and get it on hard copy. However, when I actually started doing it, it all went by a breeze and I was finished so fast that it startled me. I would say that I didn’t plan it out very accurately and I could have stuck to my plan a bit more. I did write my plan and all the schedules but I didn’t do it on the days that I was supposed to. I worked on my project whenever and however I wanted, and I do not think that that was the best way to succeed.

Water trolleys are a very important factor of the lives of the ger districters, because it is the only way they could transport water to their homes without having to pay for a gas or hurting themselves. Some people use cars to carry their water home, but since not all people could afford to have car, water trolley is the most convenient way to carry it. Since there was no other invention that could have worked better than the water trolley, I decided that I should improve it and make it easier for people to carry it uphill.

I think it is important that we help each other out and the less unfortunates. The littlest things we do will affect the lives of thousand in numerous ways that we cannot even imagine. It is important that we help out and look out for the other people, because that could help us to grow and be responsible adults who care about the environment around them.

Criteria D- Test

Test

The following test will mainly be a checklist of what a normal water trolley should provide.

1. Do the wheels actually roll across a surface?

2. Does the trolley weigh at a reasonable weight so people are able pull/push it uphill/downhill?

3. Is it stable and not wobbly so?

4. Are the length, width, and height proportional? So it won’t tip over and fall when it is full of canisters?

Rebeakh-

1. Yes, it does the wheels seem to be very good.

2. Yes, the trolley doesn’t seem to be too heavy and doesn’t seem too weak. So, it should be able to be pushed up and down the hill, with things on it.

3. No, it isn’t. The trolley seems to be weighing just at the right weight.

4. It seems to be just right. The length and width isn’t too big or too small. It doesn’t seem to fall over that easily.

Evaluation

1) What was I supposed to do?
For our unit project, we were supposed to pick a factor that plays a minor/major role in the lives of the ger districters and improve it. Or, we could’ve invented a new invention, which could improve the lives of the people who live in the ger district.
2) What did I do?
I chose to improve the water trolley, which is a big tool which helps the people carry their heavy canisters without having to carry them. Since not all the people live near the water station, they mostly have to drag their water uphill, which is not an easy activity, especially in a cold, severe weather. Most of the water trolleys’ handles are made out of metal so it hurts the people’s hands. In addition, those people have to be carrying it uphill, so they must strongly grasp the metal bar and pull. That was one of the two issues I saw in the current trolleys. I solved the problem by covering the area which is usually held, by rubber. I considered the idea of covering the area with cloth, but thought that it would need constant cleaning, whilst the people already have enough errands on their plate. Another problem I spotted in the present trolleys was that it looked somewhat like a cage. There were metal bars horizontally and vertically, placed around the trolley. The problem is that small canisters would fall through the holes if placed in that water trolley, so it was deciphered by replacing the “bar-cage” by a metal box. The “box” would be fully covered so that no canisters would leave the premises.
3) What could I have done better? I could have made the opposite side of the handle a bit taller, since the people are going to be carrying it uphill and there is always a chance that the canisters will tip over and fall.

November 16th

Create the basic box of the trolley. If I can, insert the bars running under the box and the handle.

No changes

November 17th

Create the wheels. And try to draw something on the handle that indicates that it is not just metal like the rest of the handle.

I drew line in the midpoint of the line to indicate that it is different than the rest of the handle.

November 18th

Use colors to tell the parts apart and use a different color for the rubber part on the handle.

The colors are not too different from each other, because I didn’t want it to look like a toy.

Did my Sketches Meet the Reuirements of my Design Specification?

During my investigation, I made a few outlines about my design specifications. I have completed the first part of my Design and have don’t the sketches required by Mrs. Wilson. In my investigation, design specification, I was not very elaborate about what I wanted to make so when I was drawing my designs of my water trolley, I tried to make it as detailed as possible. I explained just about every single step of my design sketch. I’m not sure if it counts as that I followed by design specification, considering the fact that my specification was not at all detailed, because by that time, I had no idea what I wanted to do and I just went with a black guess and decided to do a water trolley. However, I do remember recalling some things about the trolley. I remember that I wanted to have cloth or rubber on the handle to prevent people from getting freezing hands in the winter time. Also, the big deal, I made both of my designs out of metal. I decided that I couldn’t use wood because it a couple of years, the wood will rot and it is not as strong and stable a metal.
