=__ 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 of the variables around us? **=

=__**Notes from Class:**__=
 * == Examples of Continuous Events: Time, Biking Distance, Years, Age of a person. These are all Independent Variables ==


 * == Examples Discontinuous Events: # of Jumping Jacks, Total # of Bags Sold, Depth. These are all Dependent Variables. ==
 * == Tables can help you because the data is already there. ==


 * == Graphs can help you because you can see the most, least progress better and also help you see the differences better. ==

=__ Problem 2.3 and Follow Up: __=

Yes because if you connect all the dots, it will show how the distance is changing by time.
=B. Make a table of (time,distance) data from the information in the graph.=
 * = =Time (hours)= ||= =Distance (miles)= ||
 * = 0 ||= 0 ||
 * = .5 ||= 8 ||
 * = 1 ||= 13 ||
 * = 1.5 ||= 22 ||
 * = 2 ||= 22 ||
 * = 2.5 ||= 30 ||
 * = 3 ||= 22 ||
 * = 3.5 ||= 31 ||
 * = 4 ||= 38 ||
 * = 4.5 ||= 49 ||
 * = 5 ||= 49 ||
 * = 5.5 ||= 56 ||
 * = 6 ||= 62 ||
 * = 6.5 ||= 71 ||
 * = 7 ||= 75 ||
 * = 7.5 ||= 81 ||

=C. What do you think happened between hour 2 and 4? Between hour 1.5 and 2?=

Between hour 2 and 4, one of the students bags where left on the table they ate of and had to go back to get it. Between hour 1.5 and 2, they had lunch and made no progress.
=D. Which method of displaying the (time,distance) data helps you see the changes better, a table or a graph? Explain your choice.=

**I added up all the miles and got 629.**
