Rain cloud in a glass

September 22, 2015

 

I love this mini science project.  It's so much fun and great for small people too.  It's all very safe for them to touch if they enjoy sensory play.

 

If you want to know how to make a rain cloud in a glass, visit my other blog, An Ordinary Life: How do clouds make rain? or click on the photo below.

 

 

 

 

Rain and clouds fascinate kids.   

 

 

 

In short...

 

Tiny water droplets inside a cloud continue to grow, they eventually become heavy enough to fall to earth. 

 

The longer explanation...

 

Clouds are a large collection of very tiny droplets of water or even ice crystals. The droplets are so small that they can float in the air. 

Clouds are made when warm air rises, now all air contains water. Nearer the ground it’s in an invisible form, most of the time, this form is water vapour.  As the water vapour warms, it expands becoming less dense and therefore floats higher

 

Some of the vapour that has risen condenses on to tiny pieces of dust and pollution that floats about in the air and forms a tiny droplet on each particle.
