6/09/08 C.T Big Idea: Observation and description of changes in the world around us are the first steps in discovering and learning about patterns. Essential Question: What are some of the variables around us?

QA. Would it make sense to connect the points on this graph?

A. Yes, I think it would make sense to connect the points on the graph, so you can see if they travel further because the line gets steeper and when they travel a shorter distance the line is not as steep.

QB. Make a table of (time, distance) data from the information in the graph.

B.
 * Time (hours) ||Distance(miles)   ||
 * 0|| 0 ||
 * 0.5 ||8  ||
 * 1 ||12  ||
 * 1.5 ||22 ||
 * 2||22 ||
 * 2.5 ||30 ||
 * 3 ||22 ||
 * 3.5 ||31||
 * 4 ||36 ||
 * 4.5|| 48 ||
 * 5||48  ||
 * 5.5||57  ||
 * 6||66  ||
 * 6.5 || 72||
 * 7||74 ||
 * 7 .5||81  ||

QC. What do you think happened between hours 2 and 4? Between hours 1.5 and 2?

C. I think what happened between hours 2-4 was that,they must have taken a turn which made them go back nearer to the city. Also between hours 1.5 and 2, there are three possibilities. They or took a turn, stopped for lunch, or they had a flat tyre.

QD. Which method of displaying the (time,distance) data helps you see the changes better,a table or graph? Explain your choice.

D.I think that the graph is better to help us seethe changes, because it shows us when the cyclists makes more progress or not.It also shows us when they stop or take turns.

__Problem 2.3 followup__ Q. Use the graph to determine the total distance the riders traveled on day 3. Explain how you determined your answer.

Ans:I think that they traveled about 82 miles on day 3, because on the graph it shows you that it is less than 85 but more than 80. So by looking at the graph I am estimating that it is about that number.
