In Prep, our Integrated topic for this term is ‘Weather in my World’.
This week the ‘Big Question’ we explored in Prep G was ‘how and why does it rain?’
We began by thinking about when after it rains and there’s puddles on the ground, where does the rain go? Does it just disappear? How?
We looked at the water cycle and learnt about how rain can evaporate into water vapor and go up to the sky to make clouds.
We looked at videos and discussed how clouds go a darker colour when it may rain soon! We learnt that it begins to rain, snow or hail when the water vapor gets too heavy in the clouds.
We then tested this idea with a ‘Rain Cloud in a Cup’ experiment! We created our rain clouds using shaving cream, and predicted how many rain drops (made up of food colour & water) we thought the cloud could hold before it ‘rained’. We then did a ‘write up’ of our experiment – drawing diagrams labelling the materials we used and explaining what we learnt from the experiment.
We had so much fun and are looking forward to more weather science experiments throughout the term!
