The experiment requires four people:


 * a jumper (to do jumping jacks)
 * a tmer (to keep track of the time)
 * a counter (to count jumping jacks)
 * a recorder (to write down the nmberof jumping jacks)

As a group, decide who will do each task. prepare a table for recording the total number of jumping jacks after every 10seconds, p to a total timeof 2 minutes (120 seconds).

Problem 1.1 Follow Up   1. =How did your jumping jack rate (the number of jumping jacks per second) change as time passed? How is this shown in your table?=
 * Time (seconds) || 0  ||  10  ||  20  ||  30  ||  40  ||  50  ||  60  ||  70  ||  80  ||  90  ||  100  ||  110  ||  120  ||
 * Total number of j.jacks || 0  ||  11  ||  23  ||  33  ||  44  ||  56  ||  68  ||  79  ||  89  ||  99  ||  108  ||  123  ||  131  ||

The rate of jumping jacks was consistent as time passed. The rate was around one and 1/10 of a jumping jack every second for 70% of the time. The other 30% of the time the rate went to9During the last ten seconds the rate went down to one jumping jack every second. This proves that the rate changed over time. 2. **What might this pattern suggest about how bike - riding speed would change over a day's time on the bicycle tour?**

This pattern might suggest that during a day of bike – riding that the rider would go faster at the beginning of the day when they started then at the end they would go slow.
