Electrical Conductivity

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
