Distance vs. Time
Est. Class Sessions: 4Developing the Lesson
Part 2. Collect and Record the Data
Each group should practice using the stopwatches and timing the walker. When the timers are proficient with the stopwatches and the walker can walk at a constant speed, they are ready to collect the data. They repeat the procedure three times and record each trial in the Distance vs. Time Data Table in the Student Activity Book as shown in Figure 1. In each table, the results for the three trials are averaged (using the median), rounded to the nearest second, and recorded under the column heading “Average” (Question 6). Each data point is recorded as an ordered pair (Time, Distance) in the last column. The data tables in Figure 1 show the median times rounded to the nearest second and the corresponding ordered pairs for each distance.
