Phase change

A phase change that i saw happen outside of class would be how i got a water bottle out of the fridge .. The water after a gpod five minutes began fogging up, then began to sweat called condensation.. This phase change shows how much the heat effects the bottle ... When it was surrounded by cold it didnt change because the molecules surrounding it were even colder than the water, but when it left the molecules were hotter than the bottle causing it to condense and become warmer throughout time

Too hot or too cold

Three things that heat up at different times are water , metal , plastic

Water: the heat once applied it instantly changes temperature becuase it is not dense its substance is very easy to go rhrough which makes it easier to warm up

Metal: it takes longer than water because of how thick it is.. The metal takes eouble thime while water heating up instantly

Plastic: it is not dense but it melts faster than the metal..

         So the time rates of what goes heAting faster would be water then plastic and lastly metal

Doppler radar

"A doppler radar is a specialized radar that uses the doppler effect to produce velocity data about objects at a distance. It does this by bouncing a microwave signal off a desired target and analyzing how the object's motion has altered the frequency of  the returned signal"

Waves show alotnof things mainly the speed and the current it is at,waves are used to show weather if the radar senses a wind gust they antenae will recieve a message saying there is an object which could be dust particles, ice crystals etc..if the object they came in contact with, the sound waves would be reflected back at an incresed frequency

Interference

Construtive inteference is when two or more waves go together and they combine a whole wave, a deconstructive wave is when two waves meet and they and both crests line up together.

Deconstructive: when two cars get into a car crash... They both line up they do not end up on a v shape.. They crash in a vertical line. Which means two forces going together leading into one "line"

Constructive: when two ocean waves go together and they crash making another huge wave showing it is constupructive wave,

Standing Waves

Today in class we were using slinks, we used the slinkys to measure the frequency of the waves.

I learned that the more force you exorted to the slinky, the further thw wave would be from you and the wave would come back stronger than it had began..also that the wave length and frequency are alike because the lentgh is created by the amount of frequent moves you are going tonbe able to make

No effect

Something i think that should effect something would be going on a swing while on a sunny day.. You would think that while going back and forward with all your body power that the wind would set you off but it wouldn't because the wind is a weaker force compared to what is pushing the swing, i thought it would effect the swings speed or motion but it doesn't

Simple harmonic motion

What is simple harmonic motion? It is a weight hung so that it swings freely back and forth

Three good examples of simple harmoic motion is a swing , a washer on a string and lastly a spring

       Swing: it goes back and forth freely when the person moves their legs back and forth the potential energy the person puts in is what makes it move freely back and forth

          A washer on a strong: the washer applies weight on the string , the string gets its speed from when you let go of the washer.. It moves side to side without stopping.

              Spring: the spring has weight in it already it moves up and down , when it is getting pulled downward its the energy that it will have to go back up and back down, which means its a harmoic motion

Electricity Generator

The Generator im most interested in is the solar power panel. 

I choose it because it is the most easy to use , its cheap , an you wouldn't pay for all the electricty you would be using.. You would only pay for the panels you would need in order to work. How does the solar power panel work? It's panel is amde up of circuits.. Which then transfer into a wire down to house which then become electircity for your appliances at home.

Something that is bad about this generator? If the sun were ever to go out...we  wouldn't have any more electricity to run around the house

Homework check

All done :)

Circuit diagram

In class today we used symbols to indacte that an object was their, some symbols they had were a light bulb , a battery , a parallel circuit, and etc... Something about using symbols isnthat you don't have to draw out the object you want to but get to the point with a symbol, something that can make using symbols harder is that other might not understand what you might be trying to say.

Pretzel circuit

In classmroday we did a reperesentation of how a circuit works. The generator would be a person handing out pretzels , the pretzels would be the " electrons " and then we would walk around until we hit a bucket the bucket would be where we would put energy, so as much pretzels we got is how much we put out to the conductors. This is what we did in class

No Wire World

What would i name this world we live in?

well our world has three temperatures ; hot ,cold, warm. Our world has people of all different races,most of us can adapt to different languages but most can't.. Our world has different variety of foods. But one thing that makes our world different is the source of energy, we have a " energy " source flying straight down from the sky, its called lightning. That would make our world different, in planets there really isn't any weather . So if i were to name othis world it were to be feeezelandia

One crazy horrible thing that could happen if electricty was just floating all around the place would be that we could be seriously shocked and it can be damadging to our flesh that is sensitive

Electricty so far

1- elecrticty can be made in so many ways.. Through water, wind, heat

2- i have a question about electricty, are electric currents on the surface of the wire?

3-so far i have learned how a genereator can work in order to make electricity

4- i am getting better at getting to know the difference between protons and neutrons

Electric vocabulary

How is electricity made? Power stations; power stations need large amounts of energy to turn turbines, most useheat energy produced from coal. Others use water and wind. The turbines causes magnets to turn the wire.. This is a generator. The moving wire of the generator causes electrons to be made, which creates electricty. In conclusion if you have a magnet and a wire and or a spinning movement it can lead to electricity

Van de graph

Today we played with the van de graff generator, what it basicially did was remove the negative electrolytes and it became neutral becausee the van de graph was positive and the "ball" was negative, but when you touch the ven de graf and it is positive and sonis another object, they both repel from each other.

Something that would be really cool to do on the van de graf is if a soda can , can shock agiasnt the generator, why because they arent both negative one is positive and the other is negative,or the other thing that we can probably donis to hold a beach ball on one hand and see if it will float just like with the ballon experiment we did in class the other day

Insulators and conductors

What does insulator mean? 

It is a material that does not let electrons to flow... They just sit their

What is a conductor? 

Materials that electrons to move freely

Today i came in contact with a conductor. It is water, it moves freely once it leaves the tap, it doesnt just stay still, it moves around until it hits the bottom of the sink. When it flows out its atoms move in different directions it doesnt just move in one place the other drops go in different directions.

Another moment that inrealized i came into an insulator was when i looked at the floor. The hard wood floor is and insulator it doesnt move, it stays still the only moment that the hardwood would move is when you would remove and apply another one.

These were the moments when i came in contact to an insulator and a conductor
