Hi guys!
For the last couple of days we have been working on little people made out of wire. We made a mini wire-figure using pliers to bend the joints. Once we did this, we took hands and we soldered them on. Soldering is when you melt a certain type of metal, called solder. When you melt the solder, it is like glue for metal. The soldering machine gets up to 850 degrees hot, so you have to be careful around it. When you solder the hands on, you can make your solder person do whatever you want. I made my solder person running. Since one of the legs were of the ground I had to make a base for it to be able to stand. Over all I had an amazing time making the solder people.
I feel that the new invention that many car companies are trying to invent, the self-driving car is very important. I think so because many people have a struggle of driving because they cannot see well. Self-driving cars are important because they help people drive, and you don’t need to be an expert at driving, but you should know how to drive in case you need to take over. Even though all the car companies are working on the self-driving car, the hardware will pretty much be the same, the thing that will change is the software. The way you use a self-driving car is you say or you put in where you want to go and it will drive you there. To stop at the red light or brake when there is a car in front of you or if there is a pedestrian in front of you, they have sensors and switches. Self-driving cars can be the new future for driving.
In order to make a circuit, you have to have a complete circle, meaning all the wires have to connect to make a full circuit. We started off with a lightbulb, batteries and a switch, along with stripped wires that we stripped a few days before. The goal was to connect everything together to make a full circuit. We had to connect the wires to the lightbulb then connect those wires to the switch. Then we took different wires and connected those to the switch to make a full circle. We had thirty minutes to do so and you had to make sure your battery was not dead and your light bulb was working.

Hi everyone,
For the past few days, we have been using multimeters. Multimeters measure voltage. If you have never seen a multimeter, it is the sie of a big calculator and has dials on it. The red wire is positive and the black wire is negative. When you plug both wires into the multimeter you take the red one and place it on top of the positive side of the battery and you take the black one and place it on top of the positive side. Before this, you look at the battery or lightbulb or anything else and check the voltage of it. For example, if the voltage is 9 then you move the dial to 20 because the number is under twenty or you move it to ten because it is under ten. You need to move the dial to the closest number over 9. Once you do this the multimeter says a number which is your voltage. Even though the battery says 9v that is before you used it, but after you used it you have less voltage on the battery and with a multimeter, you can check that.
