__Problem 1.2- Making Graphs__

__Jumping Jacks__

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?

Notes from the class

Vocabulary

-Variable - A quanity that changes or varies. -Independent Variable- The variable that goes on the x-axis of a coordinate graph. -Dependent Variable- The variable that goes on the y-axis of a coordinate graph.

Examples from the White Board

<span style="font: normal normal normal 14px/normal Helvetica; letter-spacing: 0px; margin: 0px;">Methods and Strategies discussed in class:

<span style="font: normal normal normal 14px/normal Helvetica; letter-spacing: 0px; margin: 0px;">-Always title your graphs <span style="font: normal normal normal 14px/normal Helvetica; letter-spacing: 0px; margin: 0px;">-Make sure you label the x and y axis <span style="font: normal normal normal 14px/normal Helvetica; letter-spacing: 0px; margin: 0px;">-Always use a ruler to make lines on your coordinate graphs

<span style="font: normal normal normal 14px/normal Helvetica; letter-spacing: 0px; margin: 0px;">Questions for this problem's unit:

<span style="font: normal normal normal 14px/normal Helvetica; letter-spacing: 0px; margin: 0px;">1. How many types of variables are there? <span style="font: normal normal normal 14px/normal Helvetica; letter-spacing: 0px; margin: 0px;">2. How often are variables used?

<span style="font: normal normal normal 14px/normal Helvetica; letter-spacing: 0px; margin: 0px;">__Problem 1.2__

<span style="font: normal normal normal 14px/normal Helvetica; letter-spacing: 0px; margin: 0px;">**A. Make a graph of your jumping jack data**



<span style="font: normal normal normal 14px/normal Helvetica; letter-spacing: 0px; margin: 0px;">**B. What does your graph show about jumping jack rate as time passes? or What does your graph show about the relationship between the number of jumping jack and time?**

<span style="font: normal normal normal 14px/normal Helvetica; letter-spacing: 0px; margin: 0px;">It shows that when time starts, the difference between the number of jumping jacks done every ten seconds is large because a person would have lots of energy. But as time passes, the difference gets smaller and smaller because a person would be tired after doing jumping jacks for a period of time.

<span style="font: normal normal normal 14px/normal Helvetica; letter-spacing: 0px; margin: 0px;">Q: **Is the relationship you found between the number of jumping jacks and time easier to see in the table or the graph? Explain your answer.**

<span style="font: normal normal normal 14px/normal Helvetica; letter-spacing: 0px; margin: 0px;">A: The relationship is easier to see in the graph because the graph shows where my jumping jacks were exactly through time and when I slow down while the table just gave numbers, but didn’t really show the relationship. <span style="font: normal normal normal 14px/normal Helvetica; letter-spacing: 0px; margin: 0px;"> __[]__
