Weeks of 2/23 - 3/8
Monday 2/23 : Test on Unit L: Exponential Growth & Decay
Tuesday 2/24 (1/2 period): Review test on Unit L, Do Corrections on Test
Wednesday 2/25: Sub Day, Take packet of 5 AP Problems and try to work on as many as possible, These 5 problems are recently given AP Problems on DC & RC Circuits, Let's se what you have learned!
Thursday 2/26 (1/2 period): Start Discussion on Magnetism:
How is a Magnetic Field Produced?
What subatomic practicle is responsible for magnetism?
What are Magnetic Domains?
What is the direction of the magnetic field insdie (and outside) a bar magnet?
How is the magnetic field inside (or outside) of the Earth?
Discuss Right-Hand-Rules:
Right-Hand Rule # 1: To determine the direction of the magnetic force acting on a charged particle in an external magnetic field. Right Hand example:
Thumb: Direction of the velocity of the charged particle
Fingers: Direction of the Magnetic Field
Palm: Direction of the Magnetic Force
HW: Make sure you have read the handout Chapter 36 on magnetism/magnetic fields
Monday 3/2: Continue with Right Hand Rules: Review ideas of magnetism and magnetic fields--(electron spin, b-field of the earth, magnetic domains, similarities of electricity and magnetism, bar magnets/compasses, etc.)
RHR # 1: Charged particle moving in an external magnetic field--Determine the direction of the magnetic force on the particle
RHR # 2: Current-Carrying Wire--Determine the direction of the magnetic force on the wire
RHR # 3: Current Carrying Wire--Determine the direction of the magnetic field surrounding the wire
RHR # 4: Solenoid--Determine the direction of the magnetic field inside the solenoid
Continue with practice for the RHRs, Introduce Station Lab Activities
HW: Practice with RHRs (pages 4 & 5 from objective packet)
Tuesday 3/3 (1/2 Period): Check & Go over HW from packet (pages 4 & 5), Re-Introduce Lab Activities, Go from station to station & complete the analysis of the RHRs, turn in Lab
HW: WebAssign M1 & M2
Wednesday 3/4: Continue with RHR Activities, Turn in Lab Sheet for RHR Activities, Discuss Circular Motion for Magnetism, Go through 3 steps to a Bainbridge Mass Spectrometer, Complete last page of packet (page 10)
HW: WebAssign M1 (Due Tomorrow!) & M2
Thursday 3/5 (1/2 period): Discuss torque on a rectangular loop or wire in a magnetic field, Discuss motors vs. generators, GIve time to complete the conceptual questions in packet (pages 6 & 7)
HW: WebAssign M2
Friday 3/6: Give out packets for Unit N, Discuss the Law of Biot & Savart (objectives N1 & N2), Derive equation for the magnetic field away form a current-carrying wire using integration(objective N3), Discuss how to apply the Biot-Savart Law for current examples, Introduce Ampere's Law, Discuss similarities to Gauss's Law, Apply Ampere's Law for a thich current- carrying wire with uniform current density
HW: WebAssign M2 (due on Tuesday 3/10) & N1 (due on Thursday 3/12)
****Note: Quiz on magnetism RHR on Monday 3/9!!
Monday 3/9 (1/2 period): In my absence, this is the plan:
Quiz quiz on Right Hand Rules
Time to work on WebAssign
HW: WebAssign M2 (due on Tuesday 3/10) & N1 (due on Thursday 3/12)
Tuesday 3/10: Re-Introduce Ampere's Law, Try a problem finding the magnetic field around a current-carrying wire applying Ampere's Law, Check results for the case of a uniform current distribution (answers in terms of J), re-do problem for the same cases but give your answers in terms of I, Apply Ampere's Law for the case of a co-axial cable (what is the benefit of the case of outside a co-axial cable?), Discuss the application of two parallel current-carrying wires and finding the force per unit length on one wire due to the magnetic field surrounding the other wire, Demo: 2 parallel, current-carrying wires and demonstrating the force between them, Derive the equation for the magnetic field inside a solenoid using Ampere's Law (necessary derivation to remember for the test/AP test!)
HW: WebAssign N1 (due on Thursday 3/12 @ 8:20 AM)
Wednesday 3/11 (1/2 period): Finish objectives, Apply Ampere's Law for the case of a non-uniform current distribution (inside and outside of the thick wire), Introduce the Hall Effect & Explain why this case requires you to use the Left Hand Rule!, Discuss how this applies to measuring the magnetic field.
HW: WebAssign N1 (due on Thursday 3/12 @ 8:20 AM!)
Thursday 3/12: Hand Back quizzes, Introduce Lab on Magnetic Fields! Do Lab with Magnetic Fields/Magnetic Field Sensors
HW: Start reviewing for the test next week & complete WebAssign N2
Friday 3/13 (1/2 period): Continue with Magnetic Field Seonsor Lab
HW: Start reviewing for the test next week & complete WebAssign N2
Monday 3/16: Start Review for Test on Units M & N, Go through set of Google Slides, Answer any additional questions on Magnetism, Hand out additional MCQ Packet, Go Back to Lab Station & Finish Lab
HW: Finish Lab & Continue reviewing for Test
Tuesday 3/17 (1/2 period): Turn in Lab, Continue Review for Test, Practice AP Problem on Magnetism, Continue looking at extra MCQ Packet as a review for test, Start looking at AP Classroom MCQ for review for test,
HW: Review for test, Go to AP Classroom and try MC reivew questions for test
