Introduction
This experiment tests electrical conduction. Electrical conduction is the transportation of an electrical charge through a substance. This is done by the electrical charge/current being sent through the substance via electrons. These electrons carry the electrical current/charge throughout the substance’s length until another conductor is able to receive the electrons charge.

Part B:
Risk Assessment:
During the construction of “the modified hurler, “ there are many risks that need to be taken into account. For example whilst assembling the Rube Goldberg machine, large objects such as books can fall onto you and hurt you. This can be prevented by keeping a distance from the machine, firstly to not hurt yourself and secondly to ensure your not knocking over the machine. Another risk that can occur while building the Rube Goldberg machine is sharp objects. In our Rube Goldberg machine we were planning to use scissors, but we didn’t due to the risks we could have triggered. If we did use it we needed to make sure we keep distance from the machine and that the scissors are placed correctly so they don’t fly into us.

Part C and D:
An energy transformation or transfer is called an energy flow. The modified hurler that we made consisted of a lot of different energy flows. There were many different types of energy as well. The engineer’s hurler consisted of many energy flows as well.
Energy flow for Engineer’s Hurler:
Inertia trolley  EPE  KE
Pole  KE
Marble  GPE  KE
Domino  GPE  KE
Calculator  GPE  KE
Note Book  GPE  KE
Text Book  GPE  KE
Ring Binder  GPE  KE
Ping Pong Ball on Ruler  GPE  KE, GPE

Energy Flow for Modified Hurler:
Golf Ball  GPE  KE
Domino Train Effect  GPE  KE
Marble in a Tube  GPE  GPE, KE
Toy Car  KE
Domino  GPE  KE
Calculator  GPE  KE
Note Book  GPE  KE
Text Book  GPE  KE
Ring Binder  GPE  KE
Ping Pong Ball on Ruler  GPE

Lab Report Electrical Conductivity Introduction There are some substances that are capable of conducting electricity, and the reason they conduct electricity is because of the type of compound the substance is. Electrolytes or any ionic compound conduct electricity and nonelectrolytes do not conduct electricity. An Ionic compound is formed from the electrical attraction between anions and cations, typically a metal with a non-metal, except hydrogen. When an ionic compound forms, the anion…

the disassociation of Sodium Chloride: NaCl(aq)Na+ (aq)+ Cl-(aq) c. Aqueous Formic Acid—HCOOH, formic acid, is a weak electrolyte. This is due to its covalent bonds, but when added to water the acid releases some of ions that allow for little conductivity. The chemical reaction of the disassociation of Formic Acid: HCOOH(aq) H+(aq) + COOH-(aq) d. Glacial Formic Acid—Despite being a liquid, glacial formic acid is a covalent compound in pure form; it cannot ionize and become an electrolyte until…

Thermal Conductivity Heat can be transferred in three different ways: convection, radiation and conduction. Conduction is the way heat is transferred in a solid, and therefore is the way it is transferred in a heat sink. Conduction occurs when two objects with different temperatures come into contact with one another. At the point where the two objects meet, the faster moving molecules of the warmer object crash into the slower moving molecules of the cooler object. When this happens, the faster…

gel, such properties as electrical conductivity, lowering of the vapor pressure, refractive index, and sodium ion concentration remained identical in both the sol and the gel state. In support of their theory, Laing and McBain point out that Arrhenius (5) found the conductivity in gelatin-water-salt systems to be the same in both sol and gel. This aspect of the micellar theory has been extended by Gelfan (6) to protoplasm because he found that the conductivity of protoplasm remained…
