In technology we learned how to solder. We have five solder stations, each one has an iron, a third hand and a sponge. I made the body, head and legs of my guy before soldering. Then I attached the arms by getting a piece of solder and melting it in the spot on the body that I wanted it to be attached. The solder got hot really fast. After it was connected it got stuck to the third hand, the solder melted it to the hand. I got it off by melting the solder. Finally I put glue on the arm and rapped it in white to look like a pitcher.
In class we’ve been learning about closed circuits. To keep the circuit closed or open you can use a switch. We were assigned to make three switches, each switch needs to have a metal conductor such as tin foil. I wanted to make my switches unique. My first switch had a straw stuck between two wooden blocks. I punched a hole in the stick and stuck it in the stick. It also put tin foil on a pice of card board that stays on the ground. Then I put tin foil on the popsicle stick. My second switch was really simple, but our class was planning to play a game with the switches so I thought it would be fast. I got two pieces of cardboard and then I glued the tin foil on top of then. Then you press them together. For my last switch I got two pieces of cardboard and put tin foil on them. I also got a straw and punched holes in the cardboard. It stuck the straw through the holes. That makes it so you can spin the cardboard on top of each other.
It must be really hard to be color blind. One out of 20 men are color blind. Now because of advanced technology, companies are making glasses to help those people. The glasses are really cool. They’ve let some people see color for the first time. Imagine how good it would be to see in color for the first time in your life.

In technology we use a lot of different tools. Some of them are fun and others are not. I like using the soldering irons. They are effective and nerve racking. They get really hot and can burn me. The piece of solder gets hot too, especially if you’ve been using them a lot. I also like the glue gun it actually feels good when the glue gets on your skin. The saw is fun, but it is really hard. The saw kept getting stuck in the PVC pipe. The drill press is not very exciting because it does all the work.
Technology has been my favorite quarterly because I really like the project we do. My favorite project was the flashlight. My favorite tools were the soldering irons. I liked it when we got free seating because I can work on the projects with my close friends. I also liked it when we learned about atoms. Before technology I knew nothing about atoms. The circuits were fu. They sparked the idea for battery bomb which were fun to do at home.
Yesterday in class we learned about circuits. If a circuit has a direct path from the negative to the positive side of a battery the electron rush through the circuit and create heat. This causes an explosion that makes the battery really hot or it can start leaking chemicals. You only should do this if you have a controlled area that won’t catch on fire. The battery is more likely to have a big reaction if the battery has a lot of power.
In July a soccer team from Thailand got stuck in a cave after their game. They were exploring in the cave, when a monsoon struck outside. Inside the cave it was pitch black. Our task was to design a flashlight that was waterproof. We had to use the materials that are local to the people in Thailand. All we could use were PVC pipes, wires, a switch, a battery, and an LED light. First we needed to map out our design on a diagram. It had to be drawn to scale. Once we got the diagram approved, we could saw our PVC pipes to fit our design. The sawing was hard because the saw kept getting stuck in the pipe. As we each finished, we could make holes in the pipe. The holes were for the switch and light. That was pretty easy because the drill press did all the work. Finally we soldered the wires to the battery, the switch, and the light. That was the final step.
