Pretzel Circuit 😋📊

Today we made a Pretzel Circuit. We had students walking around a tape line. We had two students as light bulbs and one as a battery.  

The "battery" person gave the other students 2 pretzels which represented the energy given to the electrons. First we made a series circuit. In this circuit we had to pass all through one way which means that out of 2 volts we had to leave one at each light bulb. This is how a series circuit works. 

Then we did a parallel circuit. The people used as the battery and the light bulbs stayed the same. The only difference in this circuit is that in a parallel circuit the electrons choose which path they want to go. Each lightbulb has its own connection to the battery. Which means that each of us had to put the bolts we got from the battery to the light bulb.

No Wires World 👻

The name of my world is Electric Power!!! One cool thing I can do with no wire electricity is that I can charge my phone with just a little panel that I put under the phone: the phone will charge automatically. Amazing right! One crazy thing that can happen with this electricity flowing everywhere is that people are getting shocked with some objects they touch. Will it's dangerous cuz it does sting.

Electricity So Far 🤓

   

     1) Electricity is... a form of energy that is the result of a current
     2) So Far I learned... how to use a generator and how it lights up things with me cranking the                       generator.
     3) Electricity is... fun because... we learn how it works and we get to use things that we wouldn't                   use in any other class i.e, generators, light bulbs, and wires.
     4) I'm still confused about...  how the electricity flows through the generator and then back to the                 circuit.

     

Electric Vocab

       What is electricity? Well electricity is an energy that is the result of a current.A current is a flow of electric charges. There are objects that let these charges flow, these objects are called conductors. The objects that don't let the charges flow are called insulators. The energy that flows into the objects are atoms. Atoms are the smallest particle of an element. An example of something that the electric charges go through is a circuit. A circuit is a path along which electrical charges are carried. Now you know what electricity is and how it can flow through things. 

Van de graff 📝🙌🏼

We played with an object  called  a Van De Graff. When you turn it on it starts to make a weird noise and as you get things close to it and makes electric shocks. Well not with every object just some. This happens because there are objects that let atoms flow freely(insulators)and there are other objects that don't let atoms flow freely (conductors). 

 I would like to try mousse on a Van De Graff. I'm curious of what would happen if you put a hair product near electricity. I think that the mousse will like "melt". 

Conductors vs Insulators

Today I have learned about conductors and insulators. An  insulator is the electricity can not flow freely and in a conductor the electricity can flow freely. 

An example of an insulator is dry air that means that the electricity we'll be hard to flow freely. An expample of a conductor is wood that means that the electricity well flow freely. When I say that the electricity flows freely I mean that the atoms of the object can observe electricity freely. 

Today, I had contact with dry air. The air is so dry because it's so cold the electricity can't flow freely. This dry air is an insulator. 

Today, I also had contact with rubber. When I touched it you can feel the electricity. How? Well sometimes when I touch it I feel like a shock on my finger. This happens because we have the same kind of electricity ( positive or negative). So when I touched the rubber with the same kind of electricity as me we repel. Because it's look magnets positive and positive will repel and negative and negative. 😊🙌🏼👌🏼

   

Electric Light

   




       
                     
                  Today in class we had to light a bulb with a battery and a wire. Do you think it was possible? Well yea it was possible... first I tried and tried but I couldn't figure it out. Finally, I got it to light up... you have to put the metal part from the bottom of the blub touching one end of the metal of the battery, then when those two sides are touching you then you touch the other side of the battery with one side of the wire and the other side you touch where the battery is touching the bulb.
