In Nursery, we love to carry out science experiments and find out why or how things happen? We decided to find out how the rain falls from the clouds? We used shaving foam to create a cloud on top of the water. We then dropped food colouring into the cloud. As the cloud filled up, the food colouring fell down into the water creating a rain-like effect. The children soon realised that once the cloud became heavy, the rain began to fall. When water droplets grow heavy in the sky, gravity pulls them down from the clouds as rain, just like in the experiment.
