Exam Friday!
Today we finished up the motion maps & graphing WS that was started Friday and got all answers corrected. This will be used to refer to just like notes over the next week or so, including Thursday's lab activity.
We have an exam Friday, so be studying! The worksheets and book homework handed back today (and from the past weeks) will be relevant, reading chapter 3 (motion, velocity, displacement, etc.) will help, and reviewing graph matching, slope, etc. is important. If you want some extra speed, distance, time practice, try these: (the answers are below)
1. Traveling at 65 miles/hour, how many minutes will it take to drive 125 miles to San Diego?
2. Traveling at 25 m/s, how many meters do you travel in 1 second?
3a. Sally Leadfoot was pulled over on her way from Syracuse to Ithaca by an officer claiming she was speeding. The speed limit is 80 km/hr and Sally had traveled 47 km in 36 minutes.
How fast was Sally’s average speed? (in km per hour!)
3b. Does she deserve a ticket?
1.9 hours, 25 ☺ , 78 km/h, that depends on instantaneous speed!

Time Vault Thursday Rm 314, 7:10am
Just wanted to remind everyone to catch a glimpse of the time vault sealed 12 years ago in the 99-00 school year by Fox students just like you! Be there right after the school opens tomorrow morning, Mr. Kasey's room.
Today in class we worked with position detectors and made graphs (automatically!) :) by moving ourselves around, then tried to match some graphs that were given to us; a tough task. Groups did a great job of sharing the limited resources I had for this activity today and I think everyone gained an appreciation for the relationship between graphs of position and velocity for the same object's motion. (slope of position graph becomes the value of the velocity graph!)
Some classes also got to discuss what the slope of the velocity graph meant (when it was flat and not flat, as well as the unit that represents it)
Tomorrow (Thursday) we will discuss answers to multiple homework assignments (p.92 and the WS just submitted) and work more to relate graphs of position, velocity, and maybe something new. Here's the worksheet.

Hmwk due Wednesday! Ranking tasks, velocity
Homework due Wednesday (WS) was handed out in class today. This problem set is to help everyone practice using speed, distance, and time (plus the velocity concept) and also using vector addition to solve motion problems. This assignment will is due on Wednesday.
Forgot your copy? Page 1 Page 2
Today we discussed correct answers from the book homework from last week (I handed back and students could make corrections), then we worked on ranking tasks; change of velocity from one situation to another, and position - time graphs where we determined displacement over the time interval.
Tomorrow (Tuesday) we'll work more with graphs - actually using the position - time graphs from today's worksheet again but we will be changing some of the ways we're ranking them - they can mean different things with different assumptions.
We will also try a graphing exercise in the notes; try to make a graph of something moving at several different constant rates and do position - time graphs and see how this relates to a velocity - time graph. There will also be some time to work on homework, depending on the class.

Vector Addition! HMWK, Lab due Monday, WED hmwk
Ping-Pong Lab due Monday
List of 10 items in motion with an estimate of their speed/velocity due Monday
Today in class we learned how to add vectors and solve relative motion problems; using arrows to represent direction and speed of motion (velocity, v = speed and direction).
Vectors may be added by drawing vector arrows Tip-to-Tail (the pointed tip of one arrow is the position for the start of the tail of the next)
We worked examples like walking backward (-2 m/s) on a moving bus (8 m/s) and showing with the diagram that the resultant velocity of the person is 6 m/s.
This concept also works on the problem where a ball is thrown (-60 mph) off the back of a moving train (60 mph) and it just drops; its velocity relative to the Earth becomes zero. (an observer on the ground sees the ball drop and fall straight down!)
Most classes also worked problems involving boats crossing rivers (triangles and Pythagorean Theorem) and planes landing or taking off from aircraft carriers.
Since classes were shortened today we didn't get to go over homework (p.92) or do the ranking tasks activity - that will be for Monday.
On Monday I will be assigning a problem set to help everyone practice using speed, distance, and time (plus the velocity concept) and also using vector addition to solve motion problems. This assignment will be due on Wednesday. Want to get a head start: Page 1 Page 2

PingPong Lab due Monday, Uniform Motion Thurs-Fri
Today's lab is due on Monday. Get an extra lab sheet here.
Graphing assignment from last week (Growing and Graphing - Scientific Method WS)
AND p. 92#1-3,9,14,16,18,19 due tomorrow (Wed.) - as we were in a different room today for the lab, and you didn't see a reminder of assignments, I will accept these on Thursday as well. :)
If you need to get more data from another group and didn't finish, please just copy a set of their data and give them credit - "I copied the data table from Joe B."...
The graph and the analysis are yours to do on your own.
Tomorrow (WED) the NAVY will come to speak to us about nuclear energy and careers you might like.
Interested in getting more info from today's presentation? Contact Petty Officer Kurth or Petty Officer Simms - Kurth is often in the cafeteria at lunches and around helping at school events, and they have facebook pages:
facebook.com/pokurth (for Kurth) OR NRD St Louis Nuclear Power (for Simms)
Thursday and Friday we will work with uniform (constant speed) motion and graph things like speed and velocity along with position.
please Bring your lab journal Thursday even if you're not done; we will be sharing data collected by different groups and discussing what the graphs tell us.
Friday we will work on a Ranking Task (or two) in groups and learn about using vector diagrams to solve relative velocity problems.
Homework for Monday: (along with your lab that's due) - Make a list of 10 different things that you observe moving, and make an estimate of their rate of change of position (their v_l_c _ _ y ) :)
(the thing in blanks is just a little different from the rate of change of distance (speed).

Hrs 3,4,5 in Library Thurs, New HMWK due Fri.
I will be coaching one section of the Science for juniors and seniors taking the ACT this weekend; our ACT bootcamp - tomorrow - 3rd period to 5th period. If you're in those hours, just go straight to the library and find the rest of the class. You will likely be in the computer lab working on a lab simulation - optional assignment. Those off task may forfeit the opportunity to turn in the assignment and potentially earn extra work for their class.
Instructions for tomorrow may be found at the bottom of this post (I may edit it before Thursday).
Today we had our exam covering measurement, density, S.I., graphing, and some scientific method questions to see where you stand from your past experience. Grades for the multiple choice section will be online tonight; the short answer by Friday.
HMWK due on Friday: P.879#11-13, 21-26 and p. 884#132,135,136
Instructions for your time in the computer lab Thursday (3-5 hours only):
Today you may
work on homework: glencoe.com/ose, code C32CCDC6F4
When you finish or if you want to work at home, you have an optional assignment to work on. Follow these two links to work on the online simulation.
OFF TASK? You will forfeit your chance to get points for the optional assignment and you may end up earning EXTRA FUN for your class tomorrow. You probably don't want to see what this means.
