Tech Post #4

A project that we are doing for tech is to create a pop up box. What you have to do is create a box where when you open it a critter comes out. Materials are going to be sent home to our houses. Some materials will be wood, a mini saw, a precision cutter, small pliers, and wood rods. We can’t start yet because all he materials haven’t arrived, but they are supposed to come t his week.

For our asynchronous assignment today we learned about 3D printers.   First, you create a design using a website, some websites are Thingeverse, or Tinkercad. You could also use something someone else built, the second step is the called slicing, this method cuts u the design it make it easier to analyze. Then it would print it, People are learning to use different materials like Metal, human cells, or chocolate. With this people could make intricate designs. China has also used a giant 3D printer to [print a house that only costs 5. Below is an example fit a 3D printed house.

It was very interesting to see how people cut trees in the 1920s, 1940s, and how they do it now. In the 1920s basically all of it was done by hand, machines were only used for transporting and sawing. In the 1940s, It was similar to the 1920s. I think it was super cool how in the 1920s – 1940s they used nature to help them sometimes. For example marking trees to help transport, and also the sawmill pond so they could transport things easier. Now the whole thing is only machines. The only times people would be helping is probably steering the machines that cut down and transport the things.

Did you know that steel is made of iron and carbon?

I certainly did not know this until I watched a documentary on it. In this documentary I learned a few other things. Things I would’ve never known without watching the documentary. For example, I learned that by using a technique called the “flash graphene” you could turn the trash on our planet into graphene. The reason you could do this is because if you heat up the trash to 2,727 degrees Celsius, it would break the carbon bonds and in mere milliseconds you would get graphene. You could then use it to make steel. The picture of the glass looking thing below is actually graphene. Graphene is basically just a single layer of graphite, which is packed with carbon.

Today I did another zoom with mr Calvert, first he answered some question but then we got into the fun part, we did a 20 question long Kahoot! But what was bad about it, was that HALF of the questions were not related to technology and rather Disney movies. One person, I guess watched lots of movies so he knew most of the answers.  We did not get to finish but it was an overall fun experience.

On Tuesday I had a zoom session with Mr Calvert. We talked about bridges and structures. We did a Nearpod and in that near pod we had to answer some questions like why one side of the bridge wasn’t attached. Another thing we talked about is that how triangles were the strongest shape, and how to make steel, which is carbon and iron.

Post #7 MORE e learning

Today is Friday and it is the weekend soon which is why I am happy, But I am also very unhappy because we are having school instead spring break :c. Today it is catchup Friday where you just make sure you did everything. Yesterday I learned about metal foam and it is a metal that can change shapes. It is really cool and it could turn form a sphere to a cube.

Post #6 E learning

E learning is being continued and we are learning about metals. I learned that metals conduct electricity very well, I also learned that you can make something called metal foam, and you can make steel out of trash! It was very interesting echas what you do is melt down plastic to a puck filled with carbon, then melt it again but with a piece of iron on top then it gradually turns to steel.

Post #5 Atoms

Because of the corona virus, we have to stay home, the e learning we are doing for technology is atoms. So far i learned that atoms are super small, and they are made of 3 parts. Electrons, neutrons, and protons. The electrons surround the protons and neutrons. The middle is called the nucleus. The protons have a positive charge, the neutrons have a neutral charge,  and electrons have a negative charge. If you keep adding neutrons, the only thing that would change is the mass. If you add protons, the atom would change. I learned that there are like 118 elements on the periodic table. A the number on them is the number of protons.

Post #4 Soldering

On Monday we started a soldering project. We have learned so far how to make he outline of our projects. We started by making a circle and another circle on top so we can put a thread through. I am planning on putting a weapon inside mine, like a spear, a bow, or a sword. I think it will look cool. We also made a planning sheet before where w put drawings of what we wanted to create, we had to make 15. Below is the piece I made.
