Student Learning Goals:By the end of this lesson, students should...> Be able to analyze a technology that uses gravitational, electric, or magnetic fields

; > Use appropriate terminology> Be able to use field diagrams to explain differences in the sources and directions of fields,

including, but not limited to, differences between near- Earth and distant fields, parallel plates andj point charges, straight line conductors and solenoids.Prior Knowledge:^ Charge, positive and negative> Attraction and repulsion> Newton's Law of Universal GravitationAssessment Strategies:> Q & A (oral), self-assessment

What the teacher willdo

Using the website:http://htwins.net/scale2/Relate the size of particlescompared to objects seenwith the naked eye. Movefrom planets to electron (tocompare last unit to current)Demonstrate charge bycontact and induction usingebonite rod, pith balls, andmetal-leaf electroscope.Probe students withquestions, what they think isgoing on.Guide the studentsrepresenting the idea of acoulomb. It's SI unit, whatit is related too, and how to"see" it.Electric charges of anelectron and proton. Thefields produced by thecharges.Elementary charge 1 .6 x 10-19 CGo over how a photocopierworks and the principlesinvolved. Understandingconcept questions.Depending on currentunderstanding, thesequestions will be reviewedas a class or individually.

What students willdo

Observe, comment, get anidea of the scales we areworking with.

Determine whatinteractions are takingplace within the demos.Other examples of theseinteractions.

Examine the SI unitcoulomb.

[Student "Chalkboard" Notes:; Charge by contact -> physically touching and transferring electronsI Charge by Induction -> When brought close one charge repels the opposite to a distance as far aspossible (metal leaf electroscope)

1 C = 1 A»s1 Coulomb = electric charge passing through a 60 watt bulb in 2 seconds (DC)

Photocopier -> Light neutralizes the selenium-coated drums. Only dark areas (images on copy) remaincharged, hold toner as transferring to paper.Classroom Ready Materials:

• Sample Problem 3 with variation• Sample problem 4

E-Fields• Remember FE = kqiqi/r2 force is action-at-a-distance k =9e9 N*m2/C2

• How can this affect motion across a great span?• A puzzle in physics explained with Field Theory (physical fields and how they interact in

space and time)• CHARGES AND FIELDS• ELECTRON HOCKEY

• This is the field of force• Electric field is s=FE/q (N/C or V/m)-> e= (l/q)(kqiq2/r2) = kq/r• Field Lines

• Start at positive and go to negative• Never cross (this would mean multiple directions at one point, impossible)• While strength of charge is proportional to field lines, density does not indicate strength• Parallel Plates have equal field/force between them (ignore edging)

SAMPLE PROBLEM 2• No Electric field is present in conductors (faraday cage) (MIT Faraday Cage)

• Electrons redistribute over the surface of conductors to reach equilibrium• No net force on charges, thus field inside is zero• Electrostatic equilibrium• Real world applications (our machines and appliances in metal boxes, coaxial cable)• However, we cannot shield the outside world form a neutral conductor, as it will have an

induced charge.• Field lines meet the conductor perpendicularly.
