Lesson details

Key learning points

  1. The recovery time is the time it takes for the heart rate to return to its resting rate after exercise.
  2. Heart rate in beats per minute (bpm) can be measured by taking a person's pulse.
  3. A line graph can be plotted showing pulse rate or heart rate over time after exercise.
  4. A person's recovery time can be determined from the line graph.
  5. People who are fitter have a shorter recovery time.

Common misconception

People are either healthy or unhealthy.

Health is a range from good to ill. Fitness is one indicator of general health.

Keywords

  • Heart rate - the number of beats per minute (bpm) of the heart

  • Pulse - the heart beat felt in a blood vessel

  • Line graph - a graph displaying continuous data plotted as points joined with a line

  • Recovery time - the time it takes for a person’s heart rate to return to the resting heart rate after exercise

When students are drawing their graphs in task B it would help if you could model drawing the axes on the board. It would also be helpful to model drawing a line of best fit through the points.
