5 points each for the videos below: 

Watch this intro video on Kinematics 

 Now watch an example of the calculations for velocity 

Evaluation: /15

15/15.  your summary brilliantly done and is typed with illustrations or written in ink on a piece of paper. It shows a really thorough understanding of these concepts 

12-14. your summary is typed with illustrations or written in ink on a piece of paper. It shows a really thorough understanding of these concepts. Everything is complete

8-11. your summary is is typed with illustrations or written in pencil on a piece of paper. It shows an understanding of these concepts. Some items are not complete

0-7. You handed in a draft which is a great start, but you need to complete this

Measuring velocity

 Today we walked outside to measure the velocity of skytrain.  We found that a small segment of the fence was 1.52m .  Take a video of skytrain and, using screenshots, label the di and the df .  Determine the displacement and the elapsed time.   

1.  Draw a picture or cartoon which describes the motion of the train.  Label the fence, the train and the 1.52 section of the fence.

2.  Write down your data including the di, the df, the displacement and the time

3.  Calculate the velocity and show your work. 

Evaluation: /20

18-20. Your data is organized in screenshots and drawings on a word document or jpeg format. Your cartoon describes the motion.  Your work is organized and calculations are correct.  Your work is exceptional in communicating your data

14-17. Your data is organized in screenshots and drawings on a word document or jpeg format. Your cartoon describes the motion.  Your work is organized and calculations are correct.  Very well done

10-13. Your data is really good and you make a good start on the assignment.  It needs a little more drawing or picture documentation of the data that you are presenting

0-10. This is a good start but it is not complete

KEEP ORGANIZED AND SAFE
Keep the classroom safe
Keeping your work area safe
Keep safe with your colleagues
Keep yourself safe
KNOW THE SYMBOLS
Know the correct symbols, WHIMIS symbols


COMMUNICATE AND REACT TO AN EMERGENCY
     be familiar with emergency procedures for fire, toxins, spills, and evacuation
