| 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).
