Date: Sept 2,08 Big idea: Observation and descrition of changes in the world around us are the forst step in discovering and learning about pettern. Essential question: What are some of the variable around us? Promblem 2.5 and F.U Answers: A: Theo’s fastest record is between 80min to 100min and the speed was 20 miles per hours.

B: Theo’s slowest record is 0min, 40min, and 100min.The speed was 0 miles per hours for each of the records.

C: The speed of Theo’s changes was bumpy most of the time and he probably saw one of his competitors and he wanted to win so he speeds up. After he went pass his competitors he got tired and slowed down to catch his breath. Once he really had to pee so he immediately stop and pees on the ground. Then felt refreshing and didn’t mind about the prize and went in the pace he did before. As he cycles he sees fastest cyclist so then he got more guilty about the prize and went fastest he could to the finish line and that was the descriptions of the graph from my point of veiw.

D: I would pick the 1st because he increases his speed in the same pace to get to 15 miles per hour in 0min to 10min.

F.U 1.	It’s not possible for humans to get to another far away place in a second. 2.	In between 80min and 100min. The reason I chose those number is because he went to the highest point on the graph then suddenly drop to 0.
