  1. To Do • Grade 2/4, 6/8 quizzes • Grade PR quizzes • Give back brainstorming sheets to P1/3 • Fill out reimbursement form • Make missed office hour slips • Make video & booklet notes for Nonmechanical Energy

  2. Unit 1, Day 7 – KE in CollisionsHW Due: Conservation of Energy January 29th (odd periods) or 30th (even periods)

  3. Agenda • Announcements (2 min) • Homework Quiz (10 min) • Reflection on Yesterday’s Homework Quiz (3min) • Review Today’s HW Quiz (20 min) • Intro Activity for Class Topic (15 min) • Break (5 min) • Booklet Notes for Class Topic (10 min) • Update Learning Log (5 min) • Project Work Time (30 min) • Homework (5 min)

  4. Announcements • Please turn in your “Heal the Bay” permission slip • You are expected to return to DVD on the bus • Your HTB materials will be used in your projects; therefore missing the field trip will result in poor grades on your projects and in class

  5. Homework Quiz – Conservation of Energy • Two forms • Calculators (NOT PHONES) are allowed • Advanced Question has multiplication, algebra, and exponents • Leave answer with square root if you don’t have a calculator • U1D6 quizzes will be returned during this time

  6. Reflect on M/T’s HW Quiz • Based on your score, does this change any ofyour numbers in your learning log (1/29 or 30)? • Knowledge Targets: #9 • Reasoning Targets: F • 5: No Idea • 6: Heard it before • 7: Recall definition • 8: Recall definition & simple calculations • 9: Total beast Average for Students who Took Notes: 8.5 Average for Students who did NOT Take Notes: 6.3

  7. Review Today’s Homework Quiz • What is the definition of “Conservation of Energy”? • What is the equation for “Conservation of Energy”?

  8. Review Today’s Homework Quiz • Which position has: • The most KE? • The most PE? • Approximately equal amounts of KE & PE?

  9. Review Today’s Homework Quiz • If position #1 had 14J of potential energy… • How much KE & PE would the other positions probably have? PE = KE = PE = KE = PE = KE = PE = KE = PE = KE =

  10. Review Today’s Quiz • A cow is at rest at 6m high and then is dropped. What is its velocity when it is still 3m above the ground? 6 meters 3 meters

  11. Intro Activity • http://phet.colorado.edu/sims/collision-lab/collision-lab_en.html • Push tab all the way to 100% elastic • Uncheck “Velocity Vectors” • Check “Show Values” & Check “Kinetic Energy” • Press Play

  12. Intro Activity • For the 100% elastic collision: • Calculate the initial momentum • Calculate the final momentum • Is the momentum before and after the same? ( Y or N ) • Is the kinetic energy before and after the same? ( Y or N )

  13. Intro Activity • http://phet.colorado.edu/sims/collision-lab/collision-lab_en.html • Push tab all the way to 0% elastic • Uncheck “Velocity Vectors” • Check “Show Values” & Check “Kinetic Energy” • Press Play

  14. Intro Activity • For the 100% elastic collision: • Calculate the initial momentum • Calculate the final momentum • Is the momentum before and after the same? ( Y or N ) • Is the kinetic energy before and after the same? ( Y or N )

  15. Break

  16. Booklet Notes • Staple insert into your booklet • Put notes on page 13

  17. Update Learning Log • Knowledge Targets: #12 • 5: No Idea • 6: Heard it before • 7: Recall definition • 8: Recall definition & simple calculations • 9: Total beast

  18. Store • Each ticket will get you a certain amount of a material • You cannot get multiple of the same materials • Paper is unlimited

  19. Brainstorming • Based on the materials you have or will have in the future • Brainstorm 12 different steps: • Must have different causes and effects! • Brainstorm 3 simple “Final Tasks” related to your topic • Recall Specifications • Only Step 1 has human interaction • One object rises to max of 2 feet • A different object falls to min of 0 feet • 8 Steps minimum. A step: Cause  Effect • 30 seconds to 5 minutes

  20. Step #1 Cause: Effect: Step #2 Cause: Effect: Step #3 Cause: Effect: Step #4 Cause: Effect: Our Topic: __________________ Final Task Ideas: 1: _________________ because… 2: _________________ because… 3: _________________ because… Step #12 Cause: Effect: Step #5 Cause: Effect: Step #11 Cause: Effect: Step #6 Cause: Effect: Step #10 Cause: Effect: Step #9 Cause: Effect: Step #8 Cause: Effect: Step #7 Cause: Effect:

  21. Project Work Time • Brainstorming must be approved • Work time; everyone should be participating • DUE AT END OF PERIOD: Brainstorming Sheet

  22. Homework • Watch Video on “Non-Mechanical Energy” • Bring more materials to work on Rube Goldberg
