Do you ever wonder about what happens with electricity? In the article “Energy Story” written it tells you about atoms and what things need to have to be that type of object. In the article “Conducting Solutions” by Rodney Schreiner tells you about solutions and the reactions to them with electricity. In the video clip “Hands-on Science with Squishy Circuits” by AnnMarie Thomas it tells you about how simple play dough can hold electricity.
In "Energy Story" the article tells you about the makeup of an atom and the type of things that the different numbers of protons, neutrons, and electrons do and make. This article is very informative like the others, but in a different way. In this article the main focus is on the buildup of an atom.

Electricity is an interesting subject. There is so much you can learn from it, like how our lights turn on or how we make cell phones. This is all a mystery until we finally get a little bit of information in our brains. I've just read two articles, "Energy Story" and "Conducting solutions". I also watched a video called Hands-on Science with Squishy circuits. I learned so much valuable information from these resources.
The development of atomic bomb boosted the level of understanding in terms of physics and chemistry of that particular time period. Physicists started to realize that stable nuclei can be converted to unstable nuclei. Through such process, they discovered that heavy nuclei can undergo nuclear fission. While testing, they added a neutron to an isotope of Uranium 235. This resulted Uranium 235 to become unstable and break down into Barium and Krypton, releasing two to three more neutrons. The breakdown of Uranium 235 is called “fission”. When the released neutrons attach to other isotopes of Uranium 235, this can result in a chain reaction of fission. For every generation of fission, the amount of fission is doubled, and this resulted in an extreme outburst of energy. The amount of energy released by this process is related to Einstein’s famous equation “E=mc^2” (Wolf).
These three sources "Energy Story", "Conducting Solutions", and a video clip "Hands-On Science" share explanations, demonstrations, and descriptions on science experiments to accomplish its purpose. In "Energy Story," it explains the use of electricity people use in their homes, and what makes it. In the video "Hands-On Science" by AnnMarie Thomas, it shows how to make homemade playdough and compare it to store brand playdough. In "Conducting Solutions" by Rodney Schreiner, it shows how certain ions have positive and negative charges. These three sources based on science show us different experiment and how to accomplish them.
Throughout the past century, investigations of quantum and particle physics phenomena have proven to show the most significant concepts and ideas in the physical and sub-atomic world. However, the discoveries yet to be made are endless. One of the most fascinating concepts in the sub-atomic universe is the idea of spintronics. Spintronics is the quantum study of the independent angular momentum (not to be confused with the orbital angular momentum of the electron) of a particle, typically that of an electron (Introduction). An electron is a fundamental particle, with a negative charge, and is independently studied in the process of spintronic devices. The spin angular momentum of electrons is ±½ћ. Devices that use the properties
An electrode is a component of an electric circuit that connects the conventional wiring of the circuit to a conducting medium such as an electrolyte or a gas. The electrically positive electrode is called the anode and the negative electrode the cathode. If an anode and a cathode are placed in a solution of an electrolyte and a source of direct current is connected between them, the positive ions in the
The first term that I noted during the movie was Conductive Polymers. Conductive polymers are almost always organic meaning a large class of chemical compounds whose molecules contain carbon. These polymers have extended delocalized bonds which are bonds found in a molecule that do not belong to a single atom or covalent bond. They are conjugated systems of double bonds and in a aromatic systems. The conjugated systems are atoms covalently bonded with alternating single and double bonds. When the electrons are removed or added into the valence bands the electrical conductivity increases. The conductive polymer has a low conductivity until the electron is removed from the valence band called (p-doping) or (n-doping) until it becomes more conductive. The movement of the charges is what is responsible for electrical conductivity. These polymers are plastic which are organic polymers and with mechanical properties such as flexibility and elasticity.
Metals contain a sea of electrons (which are negatively charged) and which flow throughout the metal. This is what allows electric current to flow so well in all metals. An electrode is a component of an electric circuit that connects the wiring of the circuit to a gas or electrolyte. A compound that conducts in a solution is called an electrolyte. The electrically positive electrode is called the anode and the negative electrode the cathode.
These reasons are why Lithium-Ion Batteries are some of the most viable options when designing new gadgets. But, the structure of these batteries are why these batteries are being used for new gadgets. A Lithium-Ion Batt...
An atom, by definition, is the smallest part of any substance. The atom has three main components that make it up: protons, neutrons, and electrons. Protons and neutrons are within the nucleus in the center of the atom. The electrons revolve around the nucleus in many orbitals. These orbitals consist of many different shapes, including circular, spiral, and many others.
Energy is an odd concept, it is something that is neither here nor there yet has a profound impact on everything, both organic and inorganic. However, energy surrounds us in more ways than is commonly believed; it is possible that matter is only a form of energy. In fact, according to Albert Einstein, matter and energy are different forms of the same thing (“Do Antimatter and Matter Destroy Each Other?”). Through analyzing the superposition of bosons (particles without mass) and fermions (particles with mass), transformations between energy and matter, the creation of mass, and the mass of energy, the existence of what humans consider to be matter will be questioned.
The novel shows the consequences of using certain elements without knowing what to do with them. Take when David had Sodium for example. He didn’t understand the full capability of what he had on him into consideration. The fact that it could blow his house up and everyone inside it did not faze him at all. Now take the nuclear reactor for example. The reactions which cause the reactor to work are, all in all, chemistry. Without the reactions creating fission, the reactor wouldn’t produce energy and so forth. Nuclear reactors also create new elements through fission to release energy which can help further the study of chemistry. The nuclear reactor uses fission to use the nuclei of two elements and fuse them together, therefore creating a new element.
Electricity and electrical components are a major part of our lives today. Our lives pretty much come to a halt if there is a power outage or if our electrical devices stop working, sometimes we even start panicking because we are so dependent on these components that we cannot afford to lose them and their importance and use only increases as time passes. We all use these electrical devices and also electricity itself but most of us do not think about the math and physics that works behind all of these things.
The invisible bits of negatively charged matter that move between objects are called electrons. The words electron, electricity, and electronics all come from the Greek word for amber – elektron. The transfer of electrons explains the electric force that attracts the balloon to the wool. Rubbing the neutral balloon with the wool cloth allows some electrons to leave the wool and stick to the balloon.
Scientists from earlier times helped influence the discoveries that lead to the development of atomic energy. In the late 1800’s, Dalton created the Atomic Theory which explains atoms, elements and compounds (Henderson 1). This was important to the study of and understanding of atoms to future scientists. The Atomic Theory was a list of scientific laws regarding atoms and their potential abilities. Roentagen, used Dalton’s findings and discovered x-rays which could pass through solid objects (Henderson 1). Although he did not discover radiation from the x-rays, he did help lay the foundations for electromagnetic waves. Shortly after Roentagen’s findings, J.J. Thompson discovered the electron which was responsible for defining the atom’s characteristics (Henderson 2). The electron helped scientists uncover why an atom responds to reactions the way it does and how it received its “personality”. Dalton’s, Roentagen’s and Thompson’s findings helped guide other scientists to discovering the uses of atomic energy and reactions. Such applications were discovered in the early 1900’s by using Einstein’s equation, which stated that if a chain reaction occurred, cheap, reliable energy could b...
