UNIT # 8 : Electromagnetism (20 Days) (2015‐2016) UNIT FOCUS: Explore the effects of nuclear, gravitational, and electromagnetic forces on objects and systems such as motors and generators to describe and predict outcomes in real‐world applications on Earth’s surface and in space. Essential Questions: Enduring Understandings:  What does it mean for charge to be quantized?  Charge is quantized.  Electricity and Magnetism are linked.  How is Coulomb’s Law similar to the Universal Law of Gravitation? How  The manipulation of the connection between electricity and magnetism is the foundation of our technical society. are they different?  Electricity is a form of energy that can be transformed by moving  How does an electric field compare to a gravitational field? electric charges doing work in various devices  Electric fields provide the force that moves charged particles  How would you determine the direction of an electric field?  A potential difference has to be maintained in order to move charges between two points.  How can conductors and insulators be identified on a periodic table?  Magnetic fields are produced around moving charges. A changing magnetic field can induce a current in a closed conductor  How do thermal conduction to electrical conduction compare? TEKS Science Processes Science Content 5C, 5D, 5E, 5F, 5G 
