==Big Idea: Observation and description of changes in the world around us are the first steps in finding and learning about patterns.==

Essential question: What are some variables around us? notes: 1. Intervals on graphs are always the same. 2. Variables can always change.

1.1 Preparing For A Bicycle Tour
Five friends wanted to start a bicycle tour group business for kids, families and schools. They decided to take a way from Philadelphia to Virginia and trying to find out how far a average rider could bike for a day.

We did an experiment in are class about jumping jacks (jj) we jumped 2 min and counted how many you did in that time.
 * Time seconds || 0 || 10 || 20 || 30 || 40 || 50 || 60 || 70 || 80 || 90 || 100 || 110 || 120 ||
 * Total number of (jj) || 0 || 12 || 22 || 31 || 41 || 50 || 60 || 71 || 80 || 89 || 100 || 113 || 124 ||

Follow up 1.1

 * 1. How did you jumping jack rate (the number of jumping jacks per second) change as time passed? How is this shown in your table? **


 * My (jj) rate was the same the whole time and i dident have any changes. The table showed that my (JJ) was stable. **


 * 2. What might this pattern suggest about how bike-riding speed would change over a day's time on the bicycle tour? **
