Pulse - Scoring Rubric Maximum Score - 9 Points

Item 1. Measure "at rest" pulse rate and record in table 1 point total

    Point Criteria:
  • Pulse beats are plausible: 7 to 25 counts per ten seconds (40-150 counts per minute).

Item 2. Measure "after exercise" pulse rates and record in table. 3 points total

    Point Criteria:
  • Records pulse at least 4 different times during the exercise (in addition to "at rest" measurement).
  • Pulse rates are plausible: 7 to 25 counts per ten seconds at the beginning (40 to 150 counts per minute).
  • Pulse rate increases with exercise (may level off or slow near the end).

Item 3. Describe how pulse changes during exercise 2 points total

    Point Criteria:
  • Description consistent with data presented.
  • Description includes identification of the trend or pattern in the data.

Item 4. Explain why pulse changes 3 points total

    Point Criteria:
  • Includes the following three elements relating to physiological needs during exercise:
    • role of muscle action (exercise results in need for more energy and oxygen in the muscles);
    • role of blood (more oxygen or food supplied by an increase in blood flow);
    • connection with heart action or pulse rate, (heart is pumping faster to supply more blood).

    Highest possible score - 9 points
