Elastic Vs Inelastic
One example of Elastic is when I throw a bouncing ball to another bouncing ball and soon BOTH balls will bounce off each other. An Example of inelastic is when I start running and I suddenly trip on my shoelace, I collide with the ground making me get stuck with the ground not wanting to get up. So the ground and I are stuck together. An elastic collisions is when 2 items bounce off of each other when they collide. An inelastic collision is when 2 items are stuck together.

Today I went to go make coffee and I boiled up hot water. While I was boiling up hot water I can see there is water bubbles in my water and I asked to my self what is going on? Well the reason why my boiling water was making bubbles was because it was evaporating. First I pored liquid into a pot and I set it in my oven. The fire was heating up the water which soon the water was turning into a gas. When the liquid was turning into a gas that is called evaporation. The reason why my boiling water was making bubbles was because the liquid was turning into a gas by evaporating. Heat was being added to the water which made the water evaporate soon turning it into a gas. At first the water was a liquid which turned into a gas by adding heat to the liquid.

Too Hot/Too Cold
Too Hot/Too Cold
3 things that heat up at different rates is Metal, Rubber, and Laundry Dryers. The Metal heats up the quickest because heat moves much faster in the metal which its a conductor. Rubber takes a long period of time to heat up (but eventually it will burn) I think rubber heats up slow because rubber is an insulator and insulators takes longer to heat up since heat moves much slower in them. Laundry Dryers take very little time to heat up because in the dryer its already producing heat while it spins around the clothes. Heat is being transferred to the wet clothes making the clothes dry up, and making the dryers spin make the clothes dry up even faster!

Doppler Radar
Doppler Radar
The doppler weather forecast is used to research about weather so that people can make predictions on precipitation, to calculate its motion and to estimate its type of rain hail snow etc. People mostly use pulse doppler-radar so that they can determine the motion of rain dopplers. How waves are used to show that weather is happening is by we see the waves in colors of the rainbow (ROYGBIV). Each color has a different wavelength. Red has the longest wavelength and violet has the shortest wavelength. A Doppler Radar is combined with satellites which allows forecasters to provide us with upcoming thunderstorms, tornadoes or any other storm that could cause damage. Doppler Radars work by the satellites measuring the changes in the frequency of the signal the radar gets to conclude the wind.

Interference
Interference
The difference between a constructive and a destructive interference is that a constructive interference is the crest of a wave that is super positioned with another crest but a difference wave it can also be a trough with a trough and all of this will allow to increase the amplitude. A destructive interference is when the crest of a wave is also super positioned with the trough of another wave but its to decrease the amplitude. An example of something that interferes and makes something smaller is when hot water is in contact with snow. The hot water makes contact with the snow making the snow dissolve into the ground. An example of something that interferes with and makes it larger is water and a plant. The plant needs water to grow which makes the plant increase in size. It becomes larger than it already is.

The lab what we did today in class was Miss Reid was trying to do a certain wave. The slinky was at two ends one in Miss Reid's hand and the other was at the laptops. Miss Reid swing the slinky up and down for 10 seconds. We had a specific wavelength which was measured in meters and the frequency (how many times Miss Reid swinged the slinky up and down for 10 seconds). Then at the end we measured the speed (frequency/10 seconds) and as a result each of them where 9.6 m/s. What I learned is that it doesn't matter the wavelength or frequency because at the end you will get the same results (depending on how long you swinged the slinky. I learned that a transverse wave is a type of wave where the particles are perpendicular meaning they go across. A compression wave is a type of wave where the particles move parallel to the direction of the energy. We got to see examples of transverse waves and compression waves.

No Effect
No Effect
Something in my life that I think should affect something but doesn't is weight on floating object. I always thought that the weight mattered if an object can float or not. The lighter the object the easier it will float, the heavier the object toe easier it will sink. But of course that's wrong. I think that weight should affect the object capability on whether or not it should float because a rock is heavy and that sinks but a penny is light and that also sinks. I know that weight does have some affect on floating object but that's not the main point. The reason why object float is because through buoyant, and the dense on the fluid.

Simple Harmonic Motion
Simple Harmonic Motion
How you would know if something is a Simple Harmonic Moition (SHM) is that the object will be hung from some type of string and will be swinging back and forth or it can also be swinging up or down. It's like a pendulum the pendulum swings back and forth.
Examples of SHM that I see everyday (well mostly)
A swing from a park
The swing goes back and forth whenever your apply force to it
Metronomes to keep a steady beat for musicians, the ones people use to play piano.
And finally one last example I see of Simple Harmonic Motion is magic. Magicians use it to hypnotize people in some other way or they use it in there little magic schemes.

Electricity Generator
Electricity Generator
The generator I'm interested in is wind power. The reason why I chose that generator is because it's very cheap and it's simple. What I mean about simple is that it doesn't use no chemicals to turn a turbine and it's easy to build. All it takes is wind to turn the turbine. The other generator's use some type of chemical (except solar power) to turn their turbine, that usually effects the earth and us since those chemicals aren't good for the environment. But here is the drawback, it gives an annoying noise that is not useful to use in any way. However luckily for the builders, the wind powers are usually build far away from houses. The wind powers can be build in a very deserted area so that it wont be annoying anyone. Fun fact: The wind power "supposedly" hurts flying birds which in my opinion I don't think it does.

Circuit Diagram
Circuit Diagram
Today in class we learned many symbols for circuit diagrams. The reason why we use these symbols for our circuit diagrams is because to make life easier. Also because so that our drawings will be precise and clear once you know the symbols meanings. Using symbols saves time because their is no need to draw an actual light bulb all you can do is a circle and inside the circle will be an X. On a circuit diagram we can see all the symbols used in it example: we can see the electric supplier known as the battery because we know that its just 2 lines (one is long and one is short) and it connects through wires. Some things the symbols make it harder to do is when the connections between other light bulbs and electric connections. Even though if you had a "real life" circuit generator where you had the generator and the wires e.t.c you can see how everything works. In a diagram you can't really
see the relationships between other things (electric connections, light bulbs e.t.c)
Something new that would help me use symbols for is building a house. Using symbols would help the construction workers locate where to apply the wood/bricks. It would just help them knowing where everything goes (windows, doors, electricity, e.t.c)

Pretzel Circuit
Pretzel Circuit
What we did in the Pretzel circuit was that we made a series circuit and a parallel circuit. In the series circuit we had 2 light bulbs and a battery source. The battery source gave energy to 30A electrons. We also had 2 voltages. In the series circuits the voltages always split and the current stays the same meaning that the 30A stayed the same and the 2 had to split. In the parallel circuit we did the same thing having 30 electrons and 2 voltages. On the parallel circuit the voltage stays the same and the electrons (circuits) had to be split. Meaning that each circuit would have 15A.

No Wires World
No Wires World
JackElec a place with no wires to light up things or make things even work, energy just moves around freely anywhere basically. A cool thing that we can do is that we would have so much electricity that we wont be needing switches to charge our phones, or home appliances(fridges microwaves e.t.c). Imagine that! A place where your phone would be charged at 100% what a relief no more worrying if you need to charge it over night or anything its just charged. JackElec would be a much easier place to live in since we wont have to deal with those pesky wires and those annoying plugs and stuff. A horrible thing that would happen is that our hair would be going EVERYWHERE we would always be having crazy hair. Our hair would always be a mess we will always be checking in the mirror to see if our hair is o.k. Also we would always be shocking everything we touch because of the static energy in our hands.

Electricity So Far
Electricity So Far
Electricity is forms of energy resulting from the existence of charged particles such as electrons or protons.
So far I learned that their is many ways on generating electricity also I learned that electricity is a form of energy resulting from a current.
Electricity is easy because I am very clear about electrons and protons.
I'm still confused about the the types of Electrostatic charge which just are Polarization.
I'm getting better at understanding the vocabulary words and what they do/mean.
I have a question about the methods of charging by using Polarization, what does Polarization do? and why is it a method of charging?

Electricity Vocabulary
Electricity Vocabulary
What I know about electricity so far is that an electron is the only part of the atom that can be moved around. If an atom has more electrons than protons, then the atom has a negative net charge. But if the atom has more protons than the electrons, then the atom has a positive net charge. Opposite charges will always attract, but when two items are the same (both negative OR positive charges) they will repel. A conductor will allow all the electrons to flow freely. But on the other hand Insulators do now allow electrons to flow freely this means that the electrons will just sit their. One last thing I know about electricity is Static Electricity this allows an item to build up extra electrons and then lets out a quick discharge shock typically it's produced by friction and that's what causes the sparks, crackling, or the attraction of dust/hair

Today in class we played with a generator, what I saw was that it caused electricity. When we tested out with a ball the ball kept touching the generator and moving away from the generator. Then we tested it out with aluminum plates, we made the aluminum plates just sit at the top at the generator and once we plugged the generator back in the aluminum plates went flying everywhere. We also tested out the a glow stick that wasn't glowing and with the generator the glow stick was glowing again.
The science that was behind all this "magic" was that the ball was attracting and repelling to the generator. The type of electricity is actually called static electricity. The generator gave electrons to the aluminum plates, the aluminum plates had enough electrons which then the aluminium plates repelled from the generator and that's what causes the aluminum plated to go flying. The generator gave enough electrons to the glow stick because the glow stick was a conductor which it made the electrons to flow easily though the glow stick which made it glow.
What I would like to see be tested on the generator is a coin (a type of copper) because probably the coin will repel from the generator then attract from it just like what the ball did.

Insulators And Conductors
Insulators And Conductors
An Insulator that I have came in contact was with a window. Inside that window had glass which all the electrons just sat their and had no harm to me. But on the other had I have experienced wires. Wires is an example of Conductors because inside that wire it has copper and inside the copper the electrons move/flow freely. Insulators do not allow electrons to flow which means all of the electrons just stand their and they don't move. The Conductors electrons they move everywhere. The more distance they have the more they get to flow around

Electric Light Bulb
Electric Light Bulb
How the Electric light bulb worked was that we had a battery and a wire and a light bulb. At one of the ends of the battery their was a wire. At the other side of the wire their was a light bulb and the light bulb was connected to the battery. This gave light to the Light Bulb because the battery has energy. The wire then sends the energy from the battery to the light bulb. This will allow the light bulb to light. I predict that this is all electricity because the battery holds the energy and the wire sends the energy to the light bulb. Even though electricity gives various known effects such a static electricity, lightning, electromagnetic, and many more. I believe that different light bulbs gives different affects to the type of energy.
