Finally after I was done with my second switch, I began to work on my third switch. At last! I decided to do a very simple switch because I was running out of time, so I decided to make a push button. A lot of people were making pushing switches, except they attached the push to a swing with rubber bands, because they needed some sort of resistance and a swing gives that. Their design was so that you had to push the swing down onto the base where there was tinfoil, and that’s how the switch worked. However, I wanted to make a different design. Instead of using rubber bands as resistance, I wanted to put my push button on something that would go up and down…. I thought for a while, thinking what could act as resistance. I was browsing through different materials, then I found what I was looking for! A pom-pom would be perfect! I cut out a piece of cardboard for the push button, and put two pom-poms on each end. Then, I used two pieces of cardboard on each side so the push button would stay in place. Finally I put tinfoil over the parts, and I was a ready to hot-glue everything together!
After I was finished with my first switch, I moved on to brainstorming my second switch. I wanted something you could slide across, so I designed a popsicle stick wrapped in tinfoil. I designed a rubber band that would be attached to the base and connected to the popsicle stick for resistance. Then I cut out a base, and covered it in tinfoil. I gathered my materials, so I was ready to hot-glue.
We started a unit on switches which was related to atoms and electricity. We would make three working switches to play a game. Each switch was supposed to be different, so I not only wanted to meet the expectations, but I also wanted to make three original switches. My first idea that came into mind was like a standard switch, and it would have a rubber band attached for resistance. I decided my switch would be inside a box. I began measuring out the proportions of the box, and used a popsicle stick for the switch, then I cut a hole in the box for the switch. Finally, I wrapped everything in tinfoil so that the switch would work. Then I before I hot-glued everything together, I tested this on a breadboard… and it worked!
I decided not to hot-glue it yet, because I wanted to hot-glue all my switches together.
On Friday, we started learning about atoms and electricity. Many people were trying to figure out why amber would attract light things like feathers. Many people had different theories. Mr. Calvert had us each get a PVC pipe and a piece of cloth for an experiment. Then he gave each table a glass jar that was closed and a metal wire going from inside the jar through the cap out of the jar. At the end of the wire there was a piece of tinfoil. When you rubbed the PVC pipe on the piece of cloth and moved it near the jar, the piece of tinfoil would move with your pipe.
An atom has protons and neutrons which are in the nucleus, and the electrons are outside of the nucleus. Protons are a positive charge, neutrons are a neutral charge, and electrons are a negative charge.
You start with a grapefruit sized ball. In order to see the atoms inside the grapefruit, you would have to make the size of the grapefruit as big as the earth, and the atoms would be only as big as a blueberry. And to see the nucleus the size of a marble, the blueberry would have to be the size of a professional football stadium. The electrons are outside as big as little fruit flies, zapping around in little flashes of light, almost teleporting.
Protons repel each other, but the neutrons stay between the protons.
The amount of neutrons in an atom may only change how light or weak the atom is, but the number of protons an atom contains changes the whole type of atom.
Lightning works by having the negative charge on the bottom of the lightning cloud, and the positive charge are on the top of the cloud. The electrons below the cloud move away from the cloud because electrons don’t like being next to each other. Then
On our fourth day of Tech, we wrote blog posts (interesting – writing about blog posts on a blog post!). Our portfolio is worth 20% of our grade, so I’m getting these blogs done before I forget. Although writing these may not be the most exciting thing in the world, I think it is a great way to reflect the things I have done and the things I will do in Technology. I am able to reflect on my day, and it helps me understand what we have gone over better.
I had heard other people talk about soldering in Tech, and it seemed a big, daunting task. There were people who got burned by the soldering iron, so I was a little reluctant to solder.
On about the beginning of the second week of May, Mr. Calvert taught us the step-by-step process of making a soldering person. I liked the idea that although everyone was following the same process, each person made an unique person that spoke to them.
I wanted my person to be in the action of kicking a soccer ball, although I didn’t add a ball so I guess it could be interpreted in different ways.
We started with a piece of wire, and curled it around a pencil. Then we used pliers to wrap one side of the wire around the other. Eventually after wrapping the wire a few times around, I stopped and the two wires became the legs. Then, I manipulated a new wire for arms, and made a circle out of another wire to make a stand for support.
Finally I went to the solder station to solder my person to its arms, then my full person to its stand. It was difficult to get the solder to stick together, and get my person to look while it was kicking something AND get it to stand upright. And every time I tried to shift my solder person’s position, its arms fell off.
Also, while writing this post, I realized my person looked like it was dancing more than kicking something, so I tried to manipulate its position……. and its arms fell off. I asked Mr. Calvert if I could solder it back together, and he agreed, so I did.
I am not mad at my final product, and I’m actually pretty pleased at it.
On Monday, April 29th, we made a simple circuit using the materials listed below:
– blade switch
– battery pack
– light bulb
It was a little of trial and error to successfully connect all the wires to be able to light the lightbulb. In order to light the lightbulb, I needed to connect the wires attached to the battery pack to one side of the blade switch, and connect the other side of the blade switch to one side of the lightbulb with a regular wire, and connect the other battery wire to the other side of the lightbulb (I’m not good at explaining things, so if you’re confused just scroll down to the picture at the end). Finally, I counted down three, two, one… and flipped the switch so that there was hopefully a complete working circuit. Nothing happened, I realized aloud.
“You have to turn on the battery,” Sophie, a classmate at my table pointed out.
Whoops. Trying again, I turn my battery pack on. And the lightbulb instantly lights up.
It was gratifying to finally see
I have been excited for Technology all year since I have heard other people’s great experiences. Because of all of the dangerous machinery in the Tech Room, Mr. Calvert made it clear to us about the importance of safety. He explained all of the rules and past unfortunate experiences in order to describe the how critical it is to follow the safety rules. I appreciate his concern on our safety, and I also believe safety comes first. I am glad to be able to feel safe around the Tech Room.
On our third day of Tech, we did a really exciting activity that was a great way to review the rules. There was a box with three locks on them, and clues were around the room. There was also a bonus box to help with opening the required box. The combinations to open the locks and the clues were safety rules that helped me review them further. We had 28 minutes to open the boxes (which was less then usual because it was a CORE day), which was enough for both teams to open. There was a girl team and a boy team, which allowed for some competition. Both teams broke out, but there was some arguments between the teams. Nevertheless, it was an interesting and thrilling experience!
