3. Unit 1, Day 10 Quiz

4.  Shhhhh: If students from later periods walk in and say that they heard there wasn’t a “real” quiz, you will have double the quizzes on Mon/Tue!

5. Announcements  Friday, February 7 th – Girls Soccer Game…The Rematch!  Heal the Bay Bring lunch with you, we won’t be until 2pm

6. Reflect on M/T’s Quiz  Based on your score, does this change any of your numbers in your learning log (2/5 or 2/6)?  Knowledge Targets: #13, #14, #15  Reasoning Targets: H, I  5: No Idea  6: Heard it before  7: Recall definition  8: Recall definition & simple calculations  9: Total beast

7. Ensure booklet is finished  There are inserts for each of the LECTURES posted on my DP: dp.davincischools.org/staff/blarkin  Staple or tape them in if you are missing notes or cannot read your notes  Remember, this will be used for SLCs and POLs. I expect to see completed packets! (That means lectures AND videos)

8. Calculator  Bring a calculator to the exam  Phones will not be allowed  You have until next week to ensure you have a calculator  You must be able to square AND square root numbers

9. Review  Go through the packet  We will work on problems #1-10 today  There is paper on your table for scratch work, but do not lose the papers, otherwise you won’t have them for study materials. Alternatively, you can write in a notebook.

10. Review  Momentum – Easy If a 2kg object is moving at 4m/s, what is its momentum?

11. Review  Momentum – Difficult If a 2kg object has a momentum of 10kg*m/s, what is its velocity?

12. Review  Momentum – Difficult If an object has a momentum of 15kg*m/s and is moving at 3m/s, what is its mass?

13. Review  Impulse – Easy You impact a wall with a force of 2N. It takes 3s to complete the impact. What is your impulse?

14. Review  Impulse – Difficult You run into a wall and have an impulse of 16 kg*m/s. If you feel 4N of force, how long did it take to complete the impact?

15. Review  Impulse – Difficult You run into a wall and have an impulse of 16 kg*m/s. If you take 2s to complete the impact, what force do you feel?

16. Review  Impulse-Momentum Theorem – Difficult An airbag stops you in a collision in 2 seconds. You are 55kg heavy and you were driving at 20m/s. What is the force you will feel?

17. Review  Momentum in an Elastic Collision – Difficult A 12kg billiard ball rolls to the right at 1m/s and hits a 4kg billiard ball that is at rest. They bounce off without deforming. After the collision, the 12kg billiard ball continues to move to the right at 0.5m/s. What is the 4kg billiard ball’s final velocity AFTER collision?

18. Review  Momentum in a Perfectly Inelastic Collision – Difficult A 12kg clay ball rolls to the right at 1m/s to hit and stick to a 4kg clay ball that is at rest. What is the velocity of the combined clay ball AFTER collision?

19. Review  Momentum in an Explosion – Difficult A 1.5kg cannon is loaded with a 0.06kg ball (total mass is 1.56kg). The apparatus is at rest. The cannon is ignited and launches the 0.06kg ball forward at 75m/s. What is the velocity of the cart following the explosion?

20. Learning Log Update  Based on today’s review, does this change any of your numbers in your learning log (2/5 or 2/6)?  Knowledge Targets: #1, 2, 3  Reasoning Targets: A, B, C, D  5: No Idea  6: Heard it before  7: Recall definition  8: Recall definition & simple calculations  9: Total beast

21. Break

22. Your Task: Review  We went over the math equations together  Tomorrow we will do questions 12-23 (W, E, and P)  It is YOUR responsibility to do the vocab  Found in notes or videos  It is YOUR responsibility to do the conceptual questions  Found in notes or videos

23. Speech  For your RG, you must give a three minute speech  Each person should speak for one minute each (assuming you have three group members)  Parts of the speech  How does your rube goldberg decoration represent your topic?  What are three facts about your topic?  What is a possible solution to your topic?  How does your final step represent your topic?  Where do you see kinetic energy?  Where do you see potential energy?  Where do you see conversion of energy?

24.  Class 1: 2/3 or 2/4  Topic = Power, Project = Building  Class 2: 2/5 or 2/6  Topic = Review, Project = Building & Speech  Field Trip on Friday, 2/7  Class 3: 2/10 or 2/11  Topic = Review, Project = Building & Speech  Class 4: 2/12 or 2/13  Unit One Exam  No School on Friday, 2/14  No School on Monday, 2/17  Class 5: 2/18 or 2/19  Project Presentations Calendar Before End of Unit One

25. Homework  Watch “Unit One Review, Part Two” Video  Ensure that your Unit 1 Booklet is completely finished  Continue Working on Rube Goldberg

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

27. Building  Use Checklist  Everyone should be participating  Your topic must be seen throughout the RG, and you must justify how your “final step” or “ultimate task” is related to your topic.
