Year 4 Science Lesson

 

The year 4 class in a teacher-led discussion about evaporation and condensation.
Evaporation we say occurs when a liquid turns into a gas. Example- water on reaching its boiling point, releases vapor, which we say the liquid is evaporating. Evaporating occurs on heating and the opposite is true with condensation. 
Condensation occurs on cooling, it is when a gas turns into a liquid. Example:
While having a shower, your bathroom is filled with steam from the hot water. When it hits the cold glass of the mirror, it turns back to water and forms tiny droplets in form of a liquid. We say the gas condensed on the mirror.
Students participated in making own notes about these processes.
