Objective: Using data collected students will analyze and synthesize the data to make predictions and generalizations about the relationship between a person's height and the measure of person's arm span.
During the fall, and through the use of a Google spreadsheet and Skype, students will share data among Algebra 1 classrooms throughout the school. Once the data has been collected and generalizations about the relationship have been made, students can share their findings with other Algebra 1 classrooms throughout the district.
Students will collect data within their classroom for each student's height and arm span. (Teachers must determine the unit of measure to be used.) Once the measurements have been taken, students will enter their group data into a Google spreadsheet. Data from the spreadsheet can then be graphed by class period, then by teacher, and then by school. The graphs for each classroom may be created by hand, but data collected from a compilation of a teacher's classes and the school-wide data will be easier to graph using Excel. Students will analyze the data for trends and make predictions.
Once the data has been analyzed and generalizations are made, students can connect with other classrooms or schools via Skype to share their findings.
