We have been continuing our scientific learning. Miss McLeod's class has been doing chemical reactions and this week we did an experiment called colourful rain.
To do this experiment you will need:
500ml of water
150ml vegetable oil
food colouring (we found blue, red and green work well)
wooden spoon
large glass jar
small glass jar
We doubled the water to make a bigger volume.
Here is the experiment-
1. pour the oil into your small glass jar.
2. add some drops of food colouring to the oil
3. stir the oil and food colouring vigorously
4. pour the oil mixture into the water
5. observe
Here is a video of what happened in our experiment once we had poured the oil into the water.
The oil sits on top of the water because their different properties prevent them from mixing together. The Food colouring only mixes with the water and when it falls through it looks like colourful rain.
