In class, we started our surprise boxes. First, I measured 6 pieces of wood that were all 4 inches long and 3 inches tall. Then I cut them out with a small saw. After I finished cutting the 6 pieces, I had to even the pieces out. I did this because a lot of the pieces weren’t the same length. I made them all the same length by stacking them up and then laying them down on a cutting board. I applied pressure onto the stack of wood with the palm of my hand and started cutting the ends of the wood.
After I finished doing that, all my pieces were about the same length. I noticed that the pieces were 3.9 inches instead of 4, so that means my box would have to be smaller. Then, I cut out 2 pieces of wood that are 3 inches long and 3 inches tall. I have to make the heights of those 2 pieces 2.5 inches, so I used a ruler to measure out 2.5 inches.
Last week I finished my saw cover. I changed my design a little bit though. Instead of me sewing buttons onto it, I just decided to wrap it around with a few rubber bands. I changed this part of my design because sewing buttons is a lot more time consuming than just wrapping some rubber bands around my saw cover. I also changed the width of my cloth. Before, I wanted to cut it 2 inches so when I wrap it around, it would be 1.3 inches. When I was cutting, I felt like 2 inches was still not enough, so I changed the width to 3 inches. I got to make it last week so this is my saw cover:
The first picture is what the cloth would actually look like if it were wrapped around the saw.
For technology class, we were supposed to design a cover for a saw. I was thinking to use a piece of cloth and three or more buttons so I can tighten the cloth around the saw. I want the length of my cloth to be 4.5 inches and I want the width to be 1.3 inches. I wanted it to be 1.3 inches instead of the exact same width as the saw so then the buttons can tighten the cloth. The thickness of this cloth is about the thickness of a beach towel. I’m also going to use buttons. I am planning on using three buttons but I’ll add some more if I need to.
I’m planning on making this by first cutting out a piece of cloth that is 4.5 inches long and about 1.8 inches wide. I’m going to cut out a piece of cloth that’s 1.8 inches wide instead of 1.3 inches wide because when I put it on the saw, it’s going to be wrapped over the saw. After I cut out the piece of cloth, then I’m going to wrap it around the saw. I’m going to do that so I can determine where to sew the buttons and also where to cut the slits for the buttons to go into. Once I do that I’m going to sew the buttons onto the place I would like them to go and then I’m going to cut a number of slits onto the cloth, depending on how many buttons I’ll choose to use. This is the sketch that I drew for the design:
The invention of 3D printing has changed the way we produce objects, from tools to toys, clothing and even body parts. I learned that there are many things that could be made with 3D printing, but I never realized that there could be things in my house that were made by using a 3D printer. There’s this pineapple decoration my friend got me that can possibly be made by a 3D printer. There is also a bookmark, a plastic container, and maybe even my phone case. 3D printing also helps the environment. A lot of things are being thrown out and are really hurting the planet, but with 3D printing you can reuse those materials by making a filament out of them. You can make filaments out of plastic, metal, ceramics, or even chocolate. 3D printing also has a big impact on artists and the artistic community. 3D printing can be very useful to them because they can design whatever they want to, print it out, and wait for their object to be printed out. This requires a little less work which is why it is useful to artists. I haven’t really thought of an invention that you can 3D print and solve, but say you want to buy something that’s really expensive. Instead of buying it, you can just 3D print it. I will probably take a while, but it’s better than spending a lot of money.
For the asynchronous assignment, I watched four videos. The videos that were taken in the 1900’s and the ones taken more recently are different. I realized that there is more manual work involved in the 1900’s than now. While I was watching the video about the redwood trees, they were cutting down the trees with some sort of saw and planned out where they wanted the tree to fall. I realized how dangerous and risky that could be. First of all, the tree can possibly fall on you which is pretty dangerous. Also, I think that planning out where the tree is going to fall is pretty risky. If those people plan it out wrong, they could damage the tree and any other trees surrounding it. I was surprised to see how much logging from the 1900’s changed. The videos that I watched that were filmed more recently have barely any manual work required. Machines are the ones that cut down the trees and prepare them to be sold, not the actual people. The video that I found the most interesting was the one about the redwood. I thought the process of cutting down the trees were interesting, but also the redwood themselves. I had no idea they were that big and that they could live for so long, which is probably why redwood is very valuable to a lot of people. While I was watching that video, I wondered if anyone ever died from cutting those trees. I also wondered if anyone still cuts trees like that.
To build is to put parts together. It looks like pieces being connected together, sort of like a puzzle. I’m not the best at building anything and I don’t really have experience, but the closest thing to building that I’ve done is making a fort. While I was building this fort, I was thinking about what materials should I use and what will make this fort less likely to fall. I was building this fort with my friend, so we helped each other come up with materials to use. I don’t have or use this fort anymore because I made it a year ago. I enjoy building things but I’m not the best at it because I don’t have enough experience. I enjoy it because it’s fun to get random objects and make something out of it. Building is different from the actives that I usually do because when you build, you have to think carefully about what you’re doing. I play soccer, and soccer requires quick decision making so it’s a little hard for me to think very carefully.
I used energy this weekend by walking, jogging, and eating, which is also known as mechanical energy. I also used energy by using electricity. I used thermal energy when I was making tea by boiling a kettle. I transferred energy when I was playing soccer. The energy from my moving foot was transferred to the soccer ball when I kicked it.
Energy is the capacity to do work. Energy can only be stored or transferred and cannot be destroyed or created.
In tech, I finally started working on soldering my battery, wires, and LED light together. First, I soldered my shortest wire to my battery. Before you solder, you have to make a hook on the end of the wire with a tool. Then, you attach the hook to the battery. I cut a piece of soldering wire and heated up my soldering iron by placing it on the object I was going to solder for five seconds. Then, I took my soldering wire and I put the soldering iron on top of it, so the soldering wire would melt and harden. After that, I soldered my other wire to my switch. This was the hardest part for me to solder because there was barely any space to put my soldering iron in. Eventually, I finished and moved on to soldering my wire to my LED light.
On my LED light, there is a long leg and a short leg. The longer leg was the positive side and the shorter leg was the negative side. I had to bend the longer leg and make it as far apart as possible from the other leg because the flashlight won’t work if both wires are touching. I soldered my positive wire to the positive leg on the LED light. Finally, I had to solder all of the pieces together to connect them. After I completed that, I drilled a hole in the middle of my flashlight for my switch. Then, I put everything I soldered into the right places of my flashlight. I needed to put a cover on my switch to protect it from water. I put all my pieces together and tried it out, and luckily, it worked. This project was really fun and I’m so excited to do something new.
I didn’t write Charlotte there. It just came with the pipe.
This is the hole that the LED light will shine through.
After I have drew my sketch, I started making the outside of my flashlight. The materials I needed to make the outside of my flashlight are a straight pipe, two round caps, a saw, and a drill press. A drill press is a tool that can make holes through tough materials. The drill is similar to a drill, but you don’t have to hold the tool in your hand.
First, I made my straight pipe. I did that by getting a straight pipe, and cutting it to the measurement I wanted it to be cut. I used a saw to cut the straight pipe until the pipe was 6 1/2 inches. Then, I got two round caps. I got one round cap and drilled a hole in it with the drill press. The round cap with the hole is where the LED light will shine through. The other round cap without the hole will be put on the other side of the straight pipe. After I assembled my flashlight, I colored both round caps silver. I colored the two round caps with a silver paint marker. The next step is to solder the three wires, battery, and LED light.
