Phase Change

          A phase change that I saw today after school was when I went outside and there was a puddle of water. When I stayed a little looking at it I saw that the puddle was getting smaller and smaller. This happened because the water was evaporating which is when the water turns from liquid to a gas. This was happening because the water is receiving the heat energy of the sun. That is a phase change that I saw outside of class today.

Too Hot/Too Cold 😒😅

Three different things that heat up in different rates are plastic, metal, and paper.  

 The plastic heats up fast because of the material that it has.  It also depends on the size of the plastic. 

 The metal heats up slow because it's material is heavier and it is harder for the heat to go throw all the material. 

 The paper heats up sort of fast because the paper is very light and it is easier for the heat to go through the molecules of the paper.  🔥🕯

Doppler Radar 🤔🙄

A Doppler radar is used to find out the weather. How does it work? Well, the Doppler radar detects motion toward or away from the radar and from the locations precipitation areas.  This Doppler radar has been helpful to detect thunderstorms and to determine if the clouds rotate; which is how tornadoes are formed. 🌪🌊😅

Interference 🌊

Do you know what constructive and destructive interference is?  Well if you don't know I can tell you. 

Constructive interference is when the crest of a wave interacts with the crest of another wave to increase the amplitude. 

 Destructive interference is when the crest of a wave interacts with the trough of another wave to decrease the wave. 

 

As you can see the difference is that constructive interference is for increasing the amplitude and destructive interference is for decreasing the amplitude. 

-an example in my life is;

   When I had a problem and my friend was "helping" me, instead of helping me she said things that made my problem worse. So it decreased the point of me showing I didn't do something wrong. 

-an example of constructive is; 

  When I had a meeting at a school and I had to dress up. Well I put something good on so I could impress them. This increased my image to look good and professional. 😌

   

No Effect 😱

Something that I think should be affected by another thing is a glue stick. We use glue to stick things together... But!! Why doesn't the glue stick into the inside of the bottle? It doesn't  stick inside the bottle because the inside of the bottle has a speacial material that doesn't get sticky with the glue. 😌🤓👏🏼🙌🏼

Standing Waves 🌊

Today we did a lab called " Standing Wave Lab". In this lab we stretched out a spring and looked for the frequency, the wavelength, and it's speed. After this lab I learned that waves with different shapes have different speeds. But also tht the waves amplitude doesn't affect the waves speed. 

Electricity Generator

I'm really interested in the Hydro Electric Power generator. I chose this generator because I find it I interesting how water makes a turbine turn to make us electricity. This generator works by a dam blocking a body of water until the fills up then it releases the water which makes a turbine turn.  Its one of the better forms of electricity generation because the air is goin to be clean. One thing that is bad bout this form of electricity is finding a location to install a dam. This is a pro elm because you can't put a dam where there is a river near a city. Cuz when the dam fills the city can get flooded. But really, anywhere that there is a big body of water you can install a dam not next to a city. 😊🌊

Circuit Diagram ✏️📊👻

In a circuit diagram instead of drawing the exact thing we use symbols. We use symbols because it is easier to represent what we are trying to show. When using symbols it is easier because it takes less time to draw what we want to show. What is bad of using symbols is that if someone who is looking at it doesn't know what each symbol means then s/he will not know what is goin on in the diagram. 

But in conclusion if you want to do a circuit diagram it is easier to use symbols and to help others u can make a key where you have the symbols drawn and what each represent. 🤓✏️

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. 

      

      ☝🏼️- Phone charging w/ no wire 😱

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.
