Daily Agenda 21st to 22nd Do Now:

◦Complete/Review POGIL (1A)◦Burl the Painter Do Now (everyone else)

Warm up: ◦Exit Slip from last class (1A)◦Review Homework from last class

Flow Chart introductionFlow Chart Completion Test Review on mini white boardsReflection on materials learned for

Newton’s 1st Law

November 21st and 22nd DO NOW: • Take back your test – carousel around the

room to CHECK and MAKE CORRECTIONS

Tonight’s Homework:• Complete Newton’s 2nd Law Video

Guide, it is the same video as before, but you will focusing on a different part! You will get this later in class

November 21st and 22nd DO NOW: • From last class, take out your POGIL

activity. Find an expert who was able to answer the questions on Page1, 2, and top half of p. 3. Review your answers. You have 5 minutes to complete this task.

Exit Slips from Last Class! Take them out – 2 minutes to check a

neighbor and edit Now, we will rapidly review – YOUR

responsibility to ask for help!REMEMBER – Your answer may not be

word for word identical to the answer on the slide…and that’s ok!!!

Think about the MEANING – do your explanations/meanings match, even if it is in different words?

think!Suppose you stand on two bathroom scales with your weight evenly distributed between the two scales. What is the reading on each of the scales? What happens when you stand with more of your weight on one foot than the other?

Support Force

think!Suppose you stand on two bathroom scales with your weight evenly distributed between the two scales. What is the reading on each of the scales? What happens when you stand with more of your weight on one foot than the other?

Answer: In the first case, the reading on each scale is half your weight. In the second case, if you lean more on one scale than the other, more than half your weight will be read on that scale but less than half on the other. The total support force adds up to your weight.

Support Force

think!Two sets of swings are shown at right. If the children on the swings are of equal weights, the ropes of which swing are more likely to break?

Vectors

think!Two sets of swings are shown at right. If the children on the swings are of equal weights, the ropes of which swing are more likely to break?

Answer: The tension is greater in the ropes hanging at an angle. The angled ropes are more likely to break than the vertical ropes.

Vectors

think!In your own words, please describe why it is more difficult to do pull-ups with one arm, instead of 2. Include key terms we have used today.

think!In your own words, please describe why it is more difficult to do pull-ups with one arm, instead of 2. Include key terms we have used today.

Answer: With one arm, all of your weight is suspended from one arm…so there is a lot of tension. With 2 arms, your weight is evenly distributed (half & half) so each arm only has half the tension.

Do Now! Burl the Painter!

With a partner/group review Ch.4 Homework problems assigned from last class. Here are the BASIC answers, it is your job to CORRECT and EXPLAIN/EXPAND upon these answers! These answers are to get to start thinking! Your answers may be in different words, but still correct! COMPLETE QUESTIONS & ANSWERS will help you on a quiz!

9) Yes. Yes. Yes10) Yes. No.12) No, the elephant has more inertia 17) You feel less tension with 2 arms

19) In the same place, it is in Mechanical Equilibrium in both situations and does not speed up or slow down relative to your hand.

#9, 10, 12, 17, 19, 20, 25, 30, 36, 37

20) The pillow is moving with the same horizontal speed as the plane while the plane is in flight and is in dynamic equilibrium until it’s support force is removed.25) 30.61 kg30) Mass, Inertia, & Weight36) Weight Lifter A37) T oo much tension from the weight pulling the chain downwards.

Flow Chart In lab groups, your goal is to use the vocab

cards to create a FLOW CHART showing everything you have learned so far in Ch. 4 ◦Weight◦Mass◦Volume ◦Mechanical Equilibrium including Static & Dynamic◦Inertia◦Net Force◦Tension ◦Newton’s First Law

Flow Chart In lab groups, your goal is to use the vocab cards to create a FLOW

CHART organizing everything you have learned so far in Ch. 4 (Net Force, Inertia, Mass, Mechanical Equilibrium, etc.)

You can see a teacher for “free” cards on which you can add whatever words, symbols, equations, etc. you choose.

You can also add words, symbols (ex: arrows, +, =), boxes, etc…anything to convey your point.

Arrange on the whiteboard so that you can edit/erase/change/modify etc.

Then, once you have decided on a final product, you will trade your whiteboard marker for Crayola markers and a piece of bulletin paper.

You will create your FINAL COPY on bulletin paper, which will be presented to the class for a 24 point grade

In order to earn full credit, all group members must speak when presenting, and all concepts learned so far in Ch. 4 must be correctly presented. There’s no ‘one right way’ to do this – be creative!

You have 25 minutes to create

Test ReviewThe answers to the Chapter 2

Test are on the mini whiteboards at each of the lab stations. Check your answers with those on the white boards and make corrections accordingly.

Following, pick up a reflection exit slip from the front of the class.
