| Scoring Rubric |
Maximum Score - 10 Points |
| Item 1. Measure pulse rates and record in table -
Quality of presentation |
2 points total |
Point Criteria:
- Presents at least 2 sets of measurements in table.
- Measurements are paired: time and number of pulse beats.
- Labels table appropriately: data entries in columns identified
by headings and/or units; units incorporated into headings or
placed beside each measurement; headings or units for the number
of pulse beats include the time interval.
| Item 1. Measure pulse rates and record in table -
Quality of data |
3 points total |
Point Criteria:
- Makes at least 5 measurements (at rest, and 4 or more during
exercise).
- Pulse beats are plausible: 7 to 25 counts per ten seconds (40-150
counts per minute).
- Pulse rate increases with exercise (may level off or slow near
the end).
| Item 2. 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 3. 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).
