1. Students will count off 1-7 forming 7 groups of 4. 2. Assign each group an exercise: sit-ups, jump rope, running in place, hand weights, walking and jumping jacks. One group will be a control at rest. 3. Each student in the group will perform the exercise for a total of 20 minutes, taking a pulse rate every 2 minutes and record. 4. Students are to enter the data onto an EXEL Spreadsheet. A summation of the “20 minute” data for the 4 students is then averaged. 5. A class data is added to spreadsheet by having the students post their averages on the board. 6. A bar graph is constructed and used to help in answering the Exploration Questions.
