Experimenting with exhaling hot and cold breath

Science

• The child learns about the concept of temperature and how it affects the state of matter, as they observe the difference between hot and cold breath.
• They understand the scientific principle that air exhaled from the lungs can be warmer or colder based on the internal body temperature and the surrounding environment.
• The activity provides an opportunity for the child to learn about heat transfer and how it occurs through breathing.

Encourage the child to further explore the concept of heat transfer by conducting similar experiments with different substances and varying environmental conditions. They can also research how different animals use their breath to regulate body temperature.
