What you need:
A syringe or pipette would be handy, but not essential
First, fill 3/4’s of the jar with cold water and top with shaving cream.
A great exercise for crafty kids to practice pouring and to think about measurements.
Start by adding food colouring to the centre of the ‘cloud’. Reapply in the same spot until it begins to seep through the ‘cloud’.
Once the ‘rain’ begins to fall, add additional colours to different areas of the ‘cloud’. Olivia described the streams of food colouring as “rain dancing” in the water.
Now for the science!
Ask your crafty to think about:
– Why do clouds float? Explain that a Cloud is made up of lots and lots of water droplets, but these water droplets are so tiny and light that they float.
– Why do clouds sometimes make rain? To keep it simple, I created a mental image of water droplets banging together to make the cloud bigger and heavier.
As the cloud grows, the water droplets become too heavy and fall, creating rain.
At this point, I seized the opportunity to introduce the word “precipitation” – different forms of water falling from the sky (rain, snow, sleet).
With or without the science element, your crafty kids will be fascinated by this sensory experience. Olivia couldn’t wait to show her friends and has loved repeating the experiment time and time again.
