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

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

Agenda  Announcements (2 min)  Homework Quiz (10 min)  Reflection on Yesterday’s Homework Quiz (3 min)  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)

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

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

Reflect on M/T’s HW Quiz  Based on your score, does this change any of your 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

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

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

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 =

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

Intro Activity  http://phet.colorado.edu/sims/collision-lab/collision-lab_en.html 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 Initial Momentum of Red (kg*m/s) Initial Momentum of Green (kg*m/s) Initial OVERALL Kinetic Energy Final Momentum of Red (kg*m/s) Final Momentum of Green (kg*m/s) Final OVERALL Kinetic Energy

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 )

Intro Activity  http://phet.colorado.edu/sims/collision-lab/collision-lab_en.html 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 Initial Momentum of Red (kg*m/s) Initial Momentum of Green (kg*m/s) Initial OVERALL Kinetic Energy Final Momentum of Red (kg*m/s) Final Momentum of Green (kg*m/s) Final OVERALL Kinetic Energy

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 )

Break

Booklet Notes  Staple insert into your booklet  Put notes on page 13

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

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

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

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

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

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