Series and Parallel Circuits

A parallel circuit has multiple pathways between its beginning and end, which means it has more than one path to take. This enables it to use one path if another fails. Since they are so fail resistant, parallel circuits are used in everyday electronics such as household wiring.


A series circuit has only one path source through all of the loads and back to the source. An example of a series circuit are christmas lights since they must rap around an entire house. series_Circuit


Dryer Sheets

Dryer sheets help prevent static electricity caused by fabrics tumbling in a dryer. This static charge is built up where clothes rub together. The rubbing can knock loose electrons from some fabrics onto others. So while some fabrics may have many electrons, others could have more protons, causing them to attract to one another. Dryer sheets are naturally positively charged and provide a lubricating effect after they coat the clothing. By lubricating the clothing, friction is significantly reduced, which reduces the bonding/separating frequency that is causing the static charge to build up.  Thus, dryer sheets are typically impregnated with a heat activated, waxy substance which works as a fabric softener and coats the clothing with a very thin layer of lubrication, reducing friction and static charge buildup.

Remote Control

UnknownThe electronic I chose is a remote control. Depending on which button you press, different signals are sent to the television. I believe this is due some sort of identical wiring that is located in the cable box. This is why it is called an electronic. The electric currents that are exchanged between the remote and the television are what enables channels to change and other remote control functions. Although this is solely a prediction, I am still very puzzled about how the remote and television communicate.

Radio waves

-frequency and wave length range of your wave:

Radio wave’s frequencies vary from 300 GHz to 3 kHz. Their wavelength varies from 1 millimeter to 100 kilometers.

-placement in the EM spectrum

Radio waves have the longest wavelengths and are located on the far left of the spectrum.

– energy associated with your wave and the properties based f, wavelength, and E!

Energy associated with my wave in biomass energy because burning wood also produces heat and light and the decry of heavy isotopes that cause radiation and radio waves. Not sure about the frequencies, wavelengths, and energy associated with this action.

-2 applications of your particular type of wave. What are they used for? How are they used/why?

Radio waves are used many for communication in satellites, computers, radio communication, broadcasting, and radars. They are naturally made by lightening or other astronomical objects. Artificially, they are made by burning materials like wood. This website also shows visually how radio waves are made:

Radiolab- Color

I found the radio lab on color both intriguing and very informative. It certainly changed my perspective on how I viewed the sky, and what color means to different cultures in different periods of time. Although I have heard of the bizarreness of Homer not mentioning blue in any of his writings, I had never truly understood the reason. This all became especially clear to me with the example of one of the scientist’s daughter, Alma. This scientist and his wife agreed on never telling their child that the sky was blue. When finally asked, the scientist could see the struggle for the child to determine what color the sky exactly was. Finally, after debating between white and blue,  Alma decided the sky was blue. If Alma, or any of us really, had grown up in Homer’s time where we would not have the experience of seeing blue so often, how would we see the sky? Along with the comment on Homer’s take on colors, I found the idea of tetrachromats very interesting. The fact that there are some people out there who can see more than the “normal” human can, is really incredible. I even looked up online tests to see if I was one, but failed each test. How can this talent can improve your life’s existence? Can it at all? The tetrachromat a scientist found happened to also be an interior designer. Perhaps this skill is especially abundant to those in the arts? This remains unclear, but I found her occupation along with her newfound skill an interesting combination.


Violin: When the bow is dragged along the strings of a violin a sound is produced. Depending on which strings are touched, different sounds, pitches, and tones are produced. Without the instrument, a similar sound is produced, but it does not have the same amount of depth or is as easily heard. The stretching of the strings and the hollowness of the instrument allows the sound to be more fluid with a greater amplitude, and therefore, a louder sound.


Energy Experts:

In round one, the Energy experts stated that the most efficient source of renewable energy for Page, Arizona was solar energy. This is not a sufficient source of energy because it will be difficult to retain energy throughout the night and it will be difficult to follow the direction of the sun with the panels. Groups that would agree with the counterargument of the Energy Experts are the presidents of the American Petroleum Institute and the Navajo tribe. The American Petroleum Institute is focused on increasing the use of natural gas. Using natural gas will not only create more jobs, but it is also already the source of  27% of Arizona’s energy.  The Navajo tribe solely wants to maintain the energy resources Page, Arizona already has in order to secure the natural lands. Adding solar panels or creating solar farms will inevitably take up this clear land.

Sierra Club Presidents:

In round two, the presidents of the Sierra Club also argued that solar energy would provide the most environmentally friendly and appropriate source of renewable energy for Page, Arizona. Again, solar energy not a sufficient source of energy because it will be difficult to retain energy throughout the night, it will be difficult to follow the direction of the sun with the panels, and the solar energy farms will replace the homes of the wildlife that inhabit Page, Arizona. Groups that would agree with the counterargument against the Sierra Club presidents are the Republican Senator and Tourism officials. The Republican Senator would not agree with their argument because they do not believe in global warming. Therefore, since solar energy does not harness a lot of energy, it would not matter how environmentally friendly it is. That is why the Republican Senator chose to use Biomass as a renewable source of energy because even though it releases many air pollutants, it seems to be the most sufficient in providing energy. The tourist group would disagree with the Sierra Club presidents because places solar panel on homes and creating solar panel farms will not be visually stimulating, and therefore, would repell tourists.

Debate: Round One

After today, I think that the leading group was the energy expert group. Even though this was my group, it seemed like “Rachel Klein” and her partner had come prepared with detailed research, multiple options for a renewable energy source, and the correct conclusion for Page, Arizona’s environmental conditions compared to the other groups. Although the other groups provided good arguments, their reasoning often seemed short and sometimes even false.

“How Big Is Your Carbon Footprint?” Activity Reflection

Screen Shot 2015-02-04 at 11.04.25 AM

This is the result of my carbon footprint. It especially amazed me how we would need five earths in order to provide enough resources for every person to live like me. Although I was sick today, I am very interested to see the classes results as a collective. I consider myself pretty green when it comes to recycling and healthy when it comes to eating fresh foods. Outside sources like driving to school everyday, using technology constantly, and using the city’s public transportation can have a great effect on the environment and earth’s well-being.

Biomass Energy Source

Where does your Energy resource come from? How do we get it?

Biomass energy comes from crop animals’ waste and fiber products such as pulp, paper, lumber, plywood, and cotton. We get the energy from biomass by burnings its sources to make heat. This heat produces steam power, which generates electricity.

How is the energy used and transferred? How do we store the energy?

For thousands of years, biomass energy has been used for cooking and heating. An example of this is cooking over a fire itself, or using a fireplace for heat. Today, biomass energy is mostly used to generate heat, electricity, or to liquid fuels for motor vehicles.


Do we use a lot of it? If yes, why? If not, why not?

Although biomass energy is often used and is renewable, it can’t be used for a lot. We have not yet discovered how to use biomass energy to power planes or other larger forms of transportation. Because biomass energy is not as dense as other fuels, it does not have enough power.

Are there any social or political issues surrounding it? What is your personal opinion on the use of this resource?

Issues surrounding biomass energy are mainly environmental. Annual harvests o periodic removals of plants are not sustainable for the environment. Biomass energy also impacts the air quality from it combustion systems.
