Next, perform the two activities you chose for a period of 10 minutes each and record your data in the table. Start with the moderate activity and record your pulse for 10 seconds at two-minute intervals. Ideally, continue the activity while measuring your pulse. If that isn’t possible, stop and record your data and then quickly resume your activity.

After completing the first activity, rest until your pulse returns to your normal resting rate. Then begin the second activity, repeating the same process. Record your findings in the table.
