# P2 Pacing Guide

Marc Reif

Instruction begins on Monday, 14 August 2017. Our school is on A/B block. Each class meets five 90-minute sessions every two weeks. We have 80 blocks before the AP Exam. that is 7200 minutes or 120 hours or 5 complete days.

There are 40 blocks in the first semester and 40 blocks in the second semester before the AP 1 and 2 Exams. Some units, as noted, do not include tests.

I estimate 75 days (allowing a few days for interruptions due to state testing) of instruction before the AP 2 Exam on Wednesday, 9 May 2018.

Etkina Text Chapter 15

Labs: Potential plot on Pasco conductive paper OR electrified objects in a pan of water

Unit 3 - DC Circuits with Capacitors

[6 blocks (incl. test date) - 23 remaining - test on 10/2 or 10/3]

Etkina Text Chapter 16

Labs: Parallel Plate Capacitor; Circuit Puzzles and Kirchhoff's Laws; RC Circuit

Unit 4 - Magnetism and Induction

[6 blocks (incl. test date) - 17 remaining - test on 10/16 or 10/17]

Etkina Text Chapters 17 and 18

Labs: B-field of permanent magnets; B-field of a current-carrying wire; B-field of a slinky

Unit 5 - Fluids

[6 blocks (incl. test date) - 11 remaining - test on 11/2 or 11/3]

Etkina Text Chapters 10 and 11

Lab for fluid statics: soup can suspended from a force sensor, lowered into beaker of water resting on a scale. Another version.

Lab for fluid dynamics: PhET simulation "Fluid Flow"

Unit 6 - Thermodynamics

[7 blocks (incl. test date) - 4 remaining - Test on 11/30 or 12/1, week after Thanks. break]

Etkina Text Chapters 12 and 13

Lab: Boyle's Law; PhET Gas properties simulation

This is probably a little too fast-paced- leaves almost 1 full week before Semester 1 Finals. That has never happened for me before.

Review [13 days remaining - Mock Exam by 5/1 or 5/2]

AP 2 Exam on Wednesday, 9 May 2018.

Probably will not actually be able to maintain the actual test dates, particularly in the second semester (for instance it doesn't include interruptions due to state testing), but I hope to be just a few days off on my estimates.
