Lesson details

Key learning points

  1. Exercise is activity requiring physical effort.
  2. Regular exercise is beneficial for good physical and mental health.
  3. Exercising causes increases in breathing rate and heart rate as cells need more oxygen for cellular respiration.

Keywords

  • Exercise - Exercise is activity requiring physical effort.

  • Breathing rate - The number of breaths per minute.

  • Heart rate - The number of heart beats per minute.

  • Gas exchange - The process of oxygen diffusing from the lungs into the blood, and carbon dioxide diffusing from the blood into the lungs.

  • Cellular respiration - A chemical process in cells, which uses sugar as a fuel to provide energy for life processes.

Common misconception

Health is only made up of physical health.

Remind students that health is a range from good to ill. Physical and mental health both contribute to a person's overall health.

Ask students what happens to their bodies when they exercise. They should be able to think of lots of physiological responses such as deeper breaths and sweating.
