1 Tues April 23rd 1.Turn in stuff 2.Move Electricity to old in nb minutes to study 4.Unit “test” / Quiz 3 – Misc Electricity 5.Asst: Magnetism Guided notes: pp (Magnetism is the last unit before your final. After the final/STAR test – we will do 2 non-CA-Standards units: Astronomy & Nuclear Physics.) Open House = Thurs 6:15-8 EXTRA CREDIT – need to know Names of Lab partners AND experiment you’re doing by TODAY at midnight (I need to have tomorrow to get it all out!)

2 Changed this around substantially from 2012 to cut days for very early STAR test this year.

3 Wed April 24 1.Ppt notes: Magnetism 2.Asst: Chapter 24 Concepts on WS: Page 647 #1-4 Page 650 #5, 7, 8 Page 651 #10, 11 Page 664 #33-35,38-43, 49, 58-61, Open House = Thurs 6:15-8 EXTRA CREDIT Magnetism Quiz Fri! OPEN HOUSE Thurs, APRIL 25 th !

4 Thur April 25 1.Warm-up, see below… 2.Continue ppt & right-hand rules 3.Go over Concept problems if time (#7; #5, 64-66) 4.Asst: “Do Not Write on this Ditto” Worksheet Open House = Thurs 6:15-8 EXTRA CREDIT Magnetism Quiz Fri! Two Quiz Questions: Which diagram represents the magnetic field resulting from the current through a central wire? Which diagram most closely represents the magnetic field around a bar magnet? OPEN HOUSE TONIGHT

5 Practice Quiz, do l e f d g h i j k m o n b c a p 1.ABOVE plane of paper at a 2.BELOW plane of paper at e 3.Anywhere INSIDE the i-l circuit 4.Anywhere OUTSIDE the m-p circuit Possible answers: Left/west Right/east North/up South/down “into the paper” “out of the paper”

6 Fri April 26 1.½ hr only: Go over Concepts & other wrksht 2.½ hour = quiz 3.Asst: (see half sheet of paper) Notes chapter 7 AND for each planet Mercury through Neptune, calculate F G = Gmm/d 2 for the universal gravitational attraction (force) between the sun and that planet AND for each planet Mercury through Neptune, calculate T 2 / r 3

7 Monday April 29 1.Quickly review F = G mm / d 2 equation, and how relates to F = mg (standard 1e & 1m) 2.Go over Standard 3, using wrksht 3.HW: 36 first semester problems: On a separate sheet of paper, write the letter of the correct answer. THEN NEATLY & LEGIBLY, you must use AT LEAST 2 line per problem to explain in English why that is the answer, and/or show the formula & math work for that problem.

8 Universal Gravitation Formulas F G = Gmm / d 2 G = 6.67 x (“sto” this!) Go over HW... Biggest = Jupiter (MASSIVE!) at 4.17 x N Smallest = Neptune ( f a r a w a y !) at 6.75 x N Note – units of mass & distance MUST be in kg and meters! Start one from HW #6-15; #13...

9 Part 2 - Universal Gravitation F G = G mm / d 2 and: F g = mg So set them equal: g = Gm / d 2 (mass of object cancels, mass of planet left over!) Note – units of mass & distance MUST be in kg and meters! Using p.173, find g of the “dwarf planet” Pluto: Look at #22 from HW…

10 Std 3 See worksheet

11 Tues April 30 / Wed May 1 1.Go over Semester 1 review HW. 2.In groups, do same thing for questions HW due Thursday: Notes “Earth’s Poles Begin Magnetic Reversal” & 1 other of your choice from website… SCIENCE STAR for jr’s is Thurs AM.

12 Thurs May 2 (35 min) & Fri May 3 1.Lecture Notes & some “Guided Reading” Questions 2.Complete “Nuclear Reactions Worksheet” (½ -ditto on front of Concepts) together 3.HW due Friday: Guided Notes 4.HW due Monday: Concepts Worksheet (ch 30 & 31) Great America: MANDATORY 30 minute safety presentation on Tuesday May 12:00 PM. ALSO 30 minute mtg Wednesday May 12:00 PM.
