Dew formation is a natural process in which water vapour condenses on cool surfaces, typically during clear, calm nights when radiative cooling lowers surface temperatures below the dew point. This ...

Students will be able to develop and explain a particle-level model to describe evaporation and condensation in the context of the water cycle. The water cycle depends on the processes of evaporation ...

The second of two sessions exploring the water cycle - the way the water on Earth keeps going around and around. The sessions make reference to the way the sun and the clouds cause water droplets to ...
