Mrs Michelle Hackmann shares her science lesson experience with the Grade 00 and Grade 000 class
The recent wet weather resulted in many interesting conversations about clouds by the Grade 000 and Grade 00 learners. We talked about the shape and size of clouds and how they have varying degrees of grey. These conversations prompted us to learn more about clouds and we wanted to understand how rain falls from them. We discussed how we could use our senses to touch, taste, smell, hear and see the rain. We used: clear plastic cup, water, dropper, shaving cream and food colouring.
First, we poured some water into the plastic cups until these were about 3/4 full. Carefully, we added a layer of shaving cream to the water. The shaving cream represented clouds and the water represented the atmosphere.
Then we added a few drops of food colouring to the shaving cream. The weight of the food colouring started to push through the shaving cream and ultimately fell through the water that was in the cup! It looked just like streaks of rain falling.
I explained to my learners that the darker grey clouds were heavy with water droplets or rain (the food colouring) and that soon enough it would break free and begin falling to the ground.
The children absolutely loved watching the streams of food colouring fall like droplets of rain through the shaving cream and then swirl around in the water. They were fascinated and asked lots of great questions but also found it to be a lovely and calming experience.
