Pretzel Circuit

I was absent this day because I had an appointment, but I will answer this to the best of my ability.

As I was told, the pretzels represented volts, and the students represented the electrons. The pretzel bag was the battery. I was also told that in the series circuit, you got two pretzels and you had to give one to one light bulb and the other one to the other light bulb. But for the parallel circuit, you got to choose which light bulb you would give 2 pretzels to.

No Wires World

If I lived in a world where electricity doesn't need to flow through wires to light things up or make things work, I think it would be a really dangerous world. I would definitely name this world Free-Flow. One cool thing would be that there would be negative charge in every conductor, I think this would be cool because think about the pain your friends would go through everytime they touched sonething. But one horrible thing that could happen while this electricity flows everywhere must be the idea of getting shocked every 0.001 seconds. Water would eventually come in contact with this electricity and most of the world could definitely burn down.

Electricity So Far

Electricity is composed of equal positive, negative, and neutral charge. Electricity is very important for humanity because nowadays we use a lot of electronic devices. We also need electricity for such things as stoves, lights, and any tools that we need that require electricity. I'm getting better at understanding circuits and I think it's very important to know this because if one time the electricity goes out we at least know a base to start with in order to fix the problem.

Electric Vocabulary

Based on my knowledge about electricity, I believe it's a very fun topic to talk about and it's also very important for the human use. Electricity is made up of several things. It all starts in a nucleus, where atoms such neutrons (neutral charge) and protons (positive charge) are located. This nucleus is surrounded by electrons, which is actually negative charge. Electricity flows through conductors. Conductors are actually made up materials that allow electrons (negative charge) to flow through freely. Electricity does not flow through insulators, the electrons just sit there. For example a balloon; a balloon is an insulator because once the static energy has reached the object it just sits there and attracts positively charged objects.

Van De Graaff

Today in class as we used the Van De Graff object, I noticed myself very intrigated into the things that were going on. First thing I noticed was how the electricity was moving throughout these objects. It went from the electricity plug, to the cables that connected to the machine, this electricity traveled through a belt and the electrons from this belt were given to a piece of metal that gave the electricity to the giant metal ball. When a conductor was near this giant ball negative energy {electricity} was released to this object. I think that the physics behind this process is how the neutrons flow from the electricity all the way to this ball and it is released to other objects while being visible as well.

Insulators and Conductors

Today, I came accross a few conductors and insulators. One of the insulators was a cup made out of glass. This glass is an insulator because it blocks in the flow of electricity. One of the conductors I came accross with today was the water inside my glass. The water is actually a conductor because electricity flows through it easily in difference with the conductors. 

Electric Light

Today in class we did an activity to light up a light bulb with a battery, light bulb, and a wire. We had to place one part of the wire connected to one side of the battery, and the light bulb to the other side of the battery, then the other end of the wire (the one that it's not connected to the battery) needs to be connected to the metal part of the light bulb. I think the electricity worked by sending energy from the battery through the wires until it reached the light bulb and it lit up.
