After I built my flashlight because at that point all it looked like was a white tube (which it was). Now, I don’t have a lot of artistic skill, so I didn’t expect much of it. I decided to color it orange and red because I like those colors. At first I wanted to make it look like fire, but decided against it because I didn’t think that I could make it look good. I just colored one cap red and the other orange and colored half of the elbow red and the other half orange. Then I added a few plastic jewels on it and added a flower design. In my point of view, I still think it looks ok, but I think I will just leave it for now.
In the previous post I talked about making the plans for the flashlight. This will be about building the flashlight. After I finished drawing out the plan I had to get the fittings. Once I knew they were the right fittings, I needed to get all te pieces. I had two positive wires and one negative. I soldered these in the right order and left these in the bag. Then, I had to drill holes to fit the switch (I put it at the top) and the light (which I put in the front, obviously). Then, I had to struggle to fit the light in the hole and fit the switch and closed it all up. Then, I put a switch cover on it and glued it down. The next part would be to decorate…
In technology we have to make plans before we build things. This past week we have been making flashlights. We drew it out on a grid paper where every square was half an inch. We had to use rulers to draw out the PVC pipes and the fittings. This was especially hard because the 45 degree elbow was extremely hard to measure. Once I measured that I had to measure all the spaces and what part of the cap would go into the fitting. After that I had to draw out where the switch, light, and battery would go. Then, I had to measure the length of the wire. Because it was drawn to scale, this was one of the easier parts. After I finished drawing the plans I had to build it. But that will be in another post.
In technology we made solder people. To make these, we bent wire into a stick figure shape with a head, body and legs. It would have been much harder to bend arms into it so instead, we soldered arms on. We bent the solder people into the shape we wanted then, we bent the arms into the shape we wanted. After that we clipped the two pieces on to the third hands (things to help old the things you are soldering). We then heated up the object and soldered it together. I have made a stand for mine that resembles a snowboard and I think overall it tuned out pretty well.
In class we talked about driverless cars and how they work. They have sensors on all sides that tell which way to turn or merge very fast. They stil have wheels in case something backfires and the human in the car can take over. There is one problem though. If there was a situation where you either had to get into an accident or hit the pedestrians on the side walk you would probably be able to make a decision really quick. You have feelings and selflessness. But the car, would most likely not be able to make that decision. It would fo the thing that would seem most logical at the time. This is another reason there is always going to need a function for the driver to take over. Overall driverless cars could be a great addition to the roads and could help people in many ways.
In class we have learned about the periodic table of elements. We have also learned about electrons, neutrons and protons. Protons are positive, neutrons are neutral and electrons are negative. The number of protons and neutrons determine its electrical charge. We also learned that, as electrons move, protons stay in place. We also used electroscopes which work because of static energy. As we rub the wool on pvc pipes we create static energy. That energy attracts the electrons and with out the electrons, the protons repel and move apart.
In technology we played a game called breakout. It was almost like escape the room, but you were trying to unlock a box. It was very interesting and all the clues had things to do with the stuff we learned that week so, when we found a clue, it was easier to decipher than if it were a few weeks later. I was definitely a challenge and we had to use both ur clues. I also think it was hard because there were some things in the room that we thought were clues but they weren’t. I think it was a fun challenge and lesson.
We just finished presenting Capstone to the parents. I did fairly well, but I did forget a few points. Sometimes I would forget to say a quick fact and I wouldn’t want to go back because that would be weird. So I would just continue and no one would know. I think that this project really helped me learn, not only about tanks, but about engineering. It also helped me with public speaking which we will have to do in middle school. I also learned a few terms like, temper, explosive reactive armor, coax gun and bow gun.
I learned about how we can improve upon our designs without ever even examining a tank fully. I also found out some specific details about powerful tanks.
Capstone made me even more interested in how stuff works. I also think it’s interesting that it wasn’t that hard to find this information, but I didn’t really go into specifics.
This project was probably my favorite. This is because, we had a choice in what we learn and research. And, if we are spending a long period of time on a project, we should probably like it.
I think overall, this project was a great learning experience and if I have a research project in the future this experience will have helped me.

I finally finished my script and even my slideshow! I think once I go over it I will start rehearsing.
When answering my question I had to start with finding resources. I found a few search terms, (and I’ll be honest I really hated this part). Some that really helped me were, “How are tanks built?”, “Design of military tanks”, and “Army tanks and the process of building them”. I had some trouble creating search terms, but eventually, after typing in my search terms I already made, I formed a few new questions. I then made search terms for those questions. And, this is how most of my search terms were formed.
I think I got a good amount of notes from YouTube videos, though there weren’t that many. I think most of the extremely helpful notes came from my interview. Probably because it’s almost like a personal article. I have everything I need answers to. I will be doing a Ted-Talk for my presentation. I really want to find a way to make it more interesting though. I think some people will get bored during the presentation. If I had to do a second presentation on tanks, I would probably do something about the different flaws and advancements over the years. Only because it is something that has really interested me.
I am really excited for my presentation. I hope I do well. I am not really good at public speaking, so I think this will definitely be hard for me. But I have help.
For Capstone we require at least one site visit. I probably wasn’t going to some military base, so I went to a museum called The Museum of American Armor. It was really helpful and I got something pretty cool too.
For my site visit, I brought two things to document my visit. A notepad and my phone. I took some notes and pictures, which will probably help in my presentation. For example, one thing I learned is, when a tank is shot or penetrated, the army will try and fix it. But, once burned, they won’t touch it. The reason being, When a tank is burned, the temper on the metal is gone and a bullet can easily penetrate the metal. I also learned that there is a tank (The M18 Hellcat), that uses an airplane engine. This was extremely interesting. I also found out everything -except the guns- on the tanks were functional in the museum.
Once I got some more research about tanks, the employee took me around to see different armored vehicles and some guns. At one exhibit, the employee gave me a bullet shell from World War II. It was a really cool artifact that I might incorporate into my presentation.
Overall, I think I learned a lot of new information. Before, I thought I wouldn’t get much new information, but I was very wrong.
