HW 9-29: Review Qs & 2-1

All periods:
by tomorrow
Concept Development Worksheet 2-1

by Thursday D & E  (by Wednesday for F)
Chapter 2 Review Questions 1-25 in notebook or google doc
These are best done discussing with someone else, so find a study buddy!

HW 9-26 Cliff Diving Safety Guide

Legal disclaimer:  Medway does not condone any student jumping off of things to test this activity.  This is a mental exercise only.

Okay, now that that's clear... :)

To determine when to pull their parachute, a base jumper needs to know how high the cliff is and how fast they are traveling to allow enough time.  To determine the height of the cliff, the base jumper drops a rock and waits to hear it hit bottom, counting the time it takes to hit.

Your objective: Create a reference sheet informing them of the instantaneous speed and distance fallen for each second up to 10 seconds.

• Create a table for time (s), velocity (m/s), and distance (m).
• Calculate the final velocity and distance fallen at each second up to 10s.  Show your work for at least one velocity and one distance.  Assume your initial velocity is zero.
• Graph the position-time and velocity-time graphs.

You may create these by hand or using a computer, and work in pairs or alone.

(homework if you didn't finish in class)

HW 9-24: 2PC 31-33

All periods: Finish up those plug 'n' chugs for chapter 2.
2PC 31-33
means
chapter 2 (page 26), plug 'n' chug problems # 31, 32, and 33
need some help?  read sections 2.5-2.6

In all of these problems, an object is "falling freely" which means we ignore air resistance.
Since it is falling, the acceleration due to gravity = 9.8 m/s/s.  Any time we do labs, we'll want to use this acceleration.  When we do problems, we want to focus on concepts more than exact numbers, so its okay to round this up to 10 m/s/s.

Quiz Reflections

You have your first quizzes back; now its time to focus on what to improve!
As we discussed, we don't do re-takes, we do REFLECTIONS!

Complete a Quiz Reflection to show that you have re-learned some material or improved your skills before the next unit test and improve your quiz grade.  Details are in the document found here.

Focus on points, and you have missed the point.

Focus on learning, and the points will come.

HW 9-23: Plug 'n' Chugs Problems in the Book & EC opportunity

HW tonight all periods:  Yes, we're actually using the book!
2PC 26-30

What does that mean?

• Chapter 2 (page 26)
• "Plug 'n' Chug" problems
• #26 - 30
• show your work

Extra HW Credit Opportunity
Also, if you've turned in any late assignments, I'm offering a way to earn some of those points back.  Email me if you're interested.  It involves typing up some of our book questions in a google doc so we have online versions you can access from home.

HW 9-22 - Equation from a VT graph

D & E periods

Apply the same approach we used in class to a velocity-time graph.  Replace the symbols in the generic slope-intercept form with what they represent.

y = mx + b

• What's on the y-axis?
• What's on the x-axis?
• What does the slope (m) represent?
• What does the y-intercept (b) represent?

HW 9-19 Connecting math and science

D&E period: 
Finish 3A: Math Primer if you didn't in class
We're breaking down the walls between math class and science class.  We're really studying the same thing from two perspectives!

F period
Graphing Game - if you didn't complete  8 levels on each of the 3 worlds, you have a week to do so.  Post screenshots showing completed levels in the assignment on Its Learning by the end of the day next Friday, 9-26

Have a great weekend!

HW 9-18: Slopes & making the connection

D period:  quiz tomorrow - graphing motion

E & F periods:  3a - Math Primer
We've talked qualitatively about graphing motion, now we're taking the math that we know and making the connection.

Open House

QUIZ Thursday & Friday

E & F periods:  Quiz Thursday
D period: Quiz Friday

What's on it?
Summarize the relationship between position‐time and velocity‐time graphs for various types of motion.  You should be able go from P‐T graphs to V‐T graphs and visa‐versa, and between stories of motion to graphs of motion and visa‐versa.

What's NOT on it?
Anything numerical.  This is qualitative analysis only: fast/slow, positive/negative, increasing/decreasing, constant/changing, etc.  You won't be calculating slopes or areas...yet :)

HW 9-16: Graph Matching

All periods:
Finish Investigation 2B.  If you didn't get to open the two files (PT_Match and VT_Match), skip that part and finish the rest.  The last page is basically filling the missing graph.  If you're given a PT graph, draw the corresponding VT graph and vice-versa.  Some advice:

• Break it down into parts.  You wouldn't eat a cheeseburger in one bite.  Don't try to process the whole graph at once.
• What are you looking at?  Are you given a position graph, or a velocity graph?
• Is it changing?  Is the graph constant or changing?  If its changing, is it increasing or decreasing?  What does that mean for the corresponding graph?

HW 9-15: Motion Lab Predictions

All periods:
Finish the reflection for Investigation 1C - changing speeds if you didn't in class.
Complete predictions only for Investigation 2A - velocity-time graphs

HW 9-12, Lab Predictions

Great job getting comfortable with the equipment!  Everyone was working their way through LoggerPro by the end of the period.

You should have finished Investigation #1A in class complete with velocity-time graph predictions.

HW: complete the 1st page of Investigation #1B - predictions for moving fast/slow TOWARD the sensor this time.

I'm thinking we'll quiz over this material middle to end of next week.

HW 9-11, Graphing Motion

D period: none

E period: Graphing Motion Worksheet (fix front side), backside for HW

F period: dropped

Two videos that summarize what we've talked about thus far:
Slopes & Area: http://youtu.be/H3zm4tMRr94 (displacement = distance in this case)
Describing motion from the velocity-time graph:  http://youtu.be/RpIQaSw4Xug?list=PL410DAEBC1E784C10

HW 9-10, Graphing Motion

D & F periods:
Graphing motion worksheet (front in class), back for HW

E period dropped

HW 9-9, Graphing Motion

READ CAREFULLY!  Each class had different homework

E period
Graphing Motion worksheet FRONT SIDE (not the "quiz" on the back)

F period
Position Time & Velocity Time Graphing Matching Challenge BOTH SIDES

D period
(dropped)  Graphing stories

HW 9-8, Graphing stories & Book Covers

Complete the graphing stories activity if unfinished in class.

1. Graph each set of data
2. Write a short scenario that explains each set of data.
3. Identify what is plotted on each axis

What's the point?  Data is useless unless we can extract meaning from it.  This is a skill that needs practice.

HW 9-5: Collaboration Rubrics

Great job on the Passing Period Presentations!  Those we didn't get to, thanks for your patience, you'll present first thing Monday.

Homework tonight, all periods:
Collaboration rubrics (use the links if you need more)

• 1 self-evaluation
• 1 for each partner

How well did you work together over the past two days?  Use the rubric to reflect and circle the appropriate place.  Don't add up points or think of it as a grade; this isn't like that.  This is feedback and reflection to help you improve your skills.  Be open and honest.  If you'd like, you can make notes on the back.  

HW 9-4: Motion Concept Map

All periods: 
Create a concept map around the word MOTION.

• Brain Dump: Start with the brain dump you did in class and add to it as you see fit.  These are all the thoughts and ideas you are trying to connect together and find relationships between.
• Links: The most important part are the links between the ideas.  Make sure these have small phrases that connect the two ideas.  It may be hand-drawn or digital.

DUE:  Friday, at the beginning of class.

Here's a concept map about concept maps.  :)  Every one looks different.

Today students completed the Marshmallow Challenge. <--Click Here to see them in action.

Tom Wujec presents some surprisingly deep research into the "marshmallow problem"-- a simple team-building exercise that involves spaghetti, one yard of tape, and a marshmallow.  Who can build the tallest tower?  And why does a surprising group always beat the average?
