Energy Story Hands-On With Squishy Circuits

In the article “Conducting Solutions” I learned an electrical current is just a flow of electric charge. When a metal conducts electricity its carried by electrons moving through metal. Did you know pure water only contains

The play dough that has salt conducts electricity and play dough that has sugar has 150 time more resistance then the salt play dough and that when you put them together they create a circuit. If you put the play dough that has salt together I won’t turn the led

Hydrogen chloride gas does not conduct electricity because it is a covalent bond which is formed from two nonmetal atoms. These two nonmetals share electrons, therefore resulting in no freely moving electrons. However, in a hydrochloric acid solution water is present resulting in the solution to conduct electricity. This is because when hydrochloric acid is created, the molecules split into ions creating an acidic solution. Since it contains freely moving ions in a liquid state. Electricity can be transferred easily as well. HCl(g)+H2O(l)→HCl (aq) + O2 (g)

In paragraph two, it states "Pure water contains very few ions, so it does not conduct electricity well. When table salt is dissolved in water, the solution conducts very well, because the solutions contain ions.". In paragraph four, it explains how laundry ammonia can conduct electricity. It states "When ammonia dissolves in water, it reacts with the water and forms a few ions.". In conclusion, paragraph five explains more about how ammonia can cause electricity when it is put into a solution with vinegar.

In the last article "Conducting Solutions" the main purpose is that it explains how different materials conduct electricity. In this passage, they describe an experiment with sugar and water. It says that when sugar is dissolved in water, the solution does not conduct electricity because there are no ions in the solution. It also describes experiments with vinegar and ammonia. It says that they work well as a mixture because the ammonia reacts with the acid in vinegar and hey form a lot of

4. What are the benefits of using a light bulb as an indication of conductivity? What are the disadvantages? The benefits are: it acts as a confident and direct way of determining whether a solution should be classified as strong, weak, or non-electrolyte. A strong light would indicate a strong electrolyte. A dim light indicates a weak electrolyte, and no light indicates a non-electrolyte. However, the disadvantages are the lack of accuracy in each reading, and conclusions that aren’t necessarily precise. Each reading displays a different level of light for each bulb. Therefore, conductivity

Conducting Solutions is important in life because it apart of science. If you want to be a scientist, then you would need to know what conducting solutions is. This article also talks about ions and electrical currents. Some demonstrations of this are ammonia vinegar mixed with molecules solutions and conduct electricity. Some water contains ions which conducts electricity really well Conducting Solutions is really important to know.

Michael Gugliotta 12/3/14 Chemistry Period 8 Electrolysis Lab During this experiment, we saw electrolysis in action. Electrolysis occurs once an electrical wave hits an object. Electrolysis only occurs when it is in a salt-based or an ionic compound.

Conductor – conductor is an object or type of material that allows the flow of electrical current in one or more directions. The electrons move easily to the other side, away from the object

1. The conductivity experiment will allow us to determine the difference between ionic and molecular compounds. We will be able to identify the compounds as strong electrolytes, weak electrolytes, or nonelectrolytes. We will be able to conclude if ionic concentration and numbers of ion influence conductivity. Lastly, we will determine does polyatomic and monatomic ions influence conductivity.

After reading the second article named “Conducting Solutions”, I learned a lot about the different types of mixtures and substances on energy sources. This gave the readers follow up examples from the last article explaining more in

It starts with subatomic particles, such as protons and electrons, produce electrical fields. These relating electrical fields are composed primarily of electrons,

An Atom is the the basic building block of all matter. Atoms are made up of Particles, called: Protons, neutrons and Electrons. Protons carry a positive charge, the neutron carry 's a neutral charge and the electron carry’s a negative charge. The Atom has two main parts the Nucleus and the Electron Shell. The Nucleus contains the Protons and Neutrons. The electron Shell Contains the The electrons.

Do ionic compounds conduct electricity as (3 points) Solids No Liquids Yes Aqueous solutions (when the ionic compounds are dissolved in water) Yes Do covalent compounds conduct electricity as (3 points) Solids no Liquids No Aqueous solutions (when the covalent compounds are dissolved in water) No Part I Lab Insert completed data tables for each part of the lab. Be sure that the data tables are organized and include units when necessary. Melting Point (4 points) Conductivity (4 points) Part II Conclusion Answer the following questions in your own words, using complete sentences. Based on your observations in the lab, categorize each unidentified compound as ionic or covalent. Explain in one or two sentences why you categorized the

The outer shell of electrons that orbit the nucleus of an atom is called the valance shell. This is what makes a copper atom conduct. For a copper atom the number of electrons is one. When a charge of electricity is placed in the end of a wire the electrons move into the wire. Since there is only one electron in the valance shell of a copper atom it can be easily dislodged with a small amount of energy causing it to jump to the next atom. This will then cause the valance electron of that atom to jump to the next atom and so forth. This movement happens very fast making it possible for a large number of electrons to move through the wire. An example of a conductive atom is shown figure 1.
