Title: Gee, It’s Such A Stream Today!

Background: When certain functions can not be put off, even small delays become significant.

Process: Remember to include axis labels and units in graphs and units in all calculations.

1. Make a simple time-position graph of a student exiting class and heading toward the washroom.

    Think: is the motion continuous? at an even pace?

2. a) What is the point of reference?

    b) the frame of reference?

3. If it takes 2.8 mins for the student to stroll 60 m, what is their average velocity?

4. At 11:25 a student is 7.7 m from their classroom point and at 11:27 they are 31.5 m from it. Find their

    average velocity for this time period.

5. Plot the following data in a time-position graph describing a student’s progress back to their class.

    time (min): 0.2 0.7 1.1 3.5 4.9 5.3 6.4

    position (m): 95 79 73 53 15 10.7 2.9

6. Now, find the slope of the graph.

7. What does the slope tell us about the student’s motion?

8. Use the slope to predict how far the student might move in 3 minutes.

9. Suggest sensitive ways of collecting data about washroom visits.

10. Who would benefit from your analysis?
