ULI POst Lab

People...

Great discussion today you brought up some really important ideas.
You are doing science!
Getting answers revising information improving the reliability of data and information!
Working together for the greater good.
Here is the video clip:
Despite of where your political affiliation lies it is important that both side of the aisle be held accountable for the facts.  An err of omission is lying!!!

Key ideas

#Changing slope
#Slope of position vs. time graph

Not as Easy as Pi!!!!

• Day 44
• People this is a rare opportunity.  We have limited time to do most of the activities in class.   And never time to do them a again!  So use what you have learned to make the experiment and your measurements better.  Don't forget about bob!  "What about bob" affected the lab?
•  During my abscence
• What is the meaning of your slope?
• What is the significance to physics?
• Calculate the value of g.
• Calculate your % error. (using g=980 cm/s/s or 9.8m/s/s)

• If your value of is greater than 10% error.
• Pinpoint  and state the issue in the lab ( ok to make mistakes as long as you learn from them)
• This is a critical skill to figure out what went wrong and why?
• 
  

Fix the glitch in the lab and repeat the experiment to improve upon the error.
Keep track of the changes made to the procedure.

All labs are capable of yielding 2% error or less.

HW: GOOD GRAPH

What are the elements of a good Graph?

• Make observations.  
• Post only one observation until the entire class has posted....  There are enough for everyone to contribute.
• Are there any areas that could use improvement:
• Copy the class results in your notebook for discussion
• The graph below contains most of essential elements for future graphs

UNIT QUEST QUEST MONDAY

• DESCRIBE THE METRIC SYSTEM
• FUNDAMENTAL UNITS
• MAKE PROPER MEASUREMENTS
• USING APPROPRIATE UNIT
• USE FACTOR LABEL TO BOTH CONVERT AND CALCULATE QUANTITIES
• WRITE NUMBERS AND CALCULATE WITH PROPER SCIENTIFIC NOTATION
• BE ABLE TO TRANSLATE AND WRITE #S IN SCIENTIFIC NOTATION
• Extra credit Significant Figures

HW: 11.4.16
Calculate the area of your note card with proper sig figs in scientific notation.
in

• cm^2
• m^2
• Km^2
• mm^2

What do all the answers have in common?
If you could only use one of the above units which one would you choose?  Why?{Post to Blog}

ADOPT a physicist

Just a reminder this is the last week for ADOPT a physicist you should copy and print out your questions and correspondence and have that ready to turn in.  If you have not posted and or not  read your physicists reports you should do so immediately.

Above all else do not waste people time by posting questions that have already been answered.  Read the posts!!!
