Clouds and Frost

A cloudy sunset by R

Today we looked at how artists represent clouds in their paintings. We discussed the cloud types we had been learning about and thought about their shapes and colours. The children painted a landscape and 2 different cloudy skies. We than placed our landscape against the different cloudy backgrounds to see how the atmosphere of the painting changed.

We also did a quick experiment to see how frost forms.

1. Fill an empty can with crushed ice.
2. Stir in some salt to encourage the ice to start melting.
3. Watch and wait.

The melting ice takes heat from the can making the can really cold. Water vapour in the air surrounding the can condenses on the can. If you wait long enough, the water droplets on the outside of the can will get cold enough to freeze into frost. Remember the frost comes from the air around the can, not from the ice inside.
