Aug-26 Investigation 1 Mathematical Reflections. = Observation and description of changes in the world around us are the first steps in finding and learning about patterns. = In this investigation, you learned about variables. You made tables and graphs to show how different variables are related. These questions will help you summarize what you have learned. Questions 1: In this investigation, you conducted a jumping jack experiment, collected the data in a table, and made a coordinate graph of the data. Your table and graph showed the relationship between two variables. What were the two variables? How did one variable affect the other? The two variables are time, and number of jumping jacks. The time variable is independent, and number of jumping jacks variable is dependant.

2: A) Name some things in the world around you that vary and that can be counted or measured. Name two variables that you think are related.  : Grasses, Animals  Grasses and Cows and related together because cow eats the grass and cow reproduces.  B) Explain how you could make a graph to show the relationship between the two related variables from part a. How would you decide which variable should be on the x-axis and which should be on the y-axis?

Think about your answers to these questions, discuss your ideas with other students and your teacher, and then write a summary of your finding in your journal. In this invesgetion I think the most important things that I learned was about independently and dependent variable. I also learned that dependent variable can affect independently. Since indepedentle’s are usually time there are pattern, however dependent usually don’t have patterns. There are Y-axis and X-axix in graph.

New Vocabulary X-axis: On a coordinate graph, the line that is horizontal Y-axis: On a coordinate graph, the line that is vertical.
