Announcements

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

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

Review today s homework quiz

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 quiz1

Review Today’s Homework Quiz

  • Which position has:

    • The most KE?

    • The most PE?

    • Approximately equal amounts of KE & PE?

Review today s quiz

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

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


Intro activity1

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 activity2

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


Intro activity3

Intro Activity

Booklet notes

Booklet Notes

  • Staple insert into your booklet

  • Put notes on page 13


Update learning log

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

Store

  • Each ticket will get you a certain amount of a material

  • You cannot get multiple of the same materials

  • Paper is unlimited


Brainstorming

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
