Science- Colourful Rain

Hi everyone!

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.

Science- Chemical Reactions

Our focus for our inquiry this term is science and interactions. 

With Miss McLeod we have been learning about interactions through chemical reactions. 

Our first experiment that we did was called "Milk on the Move" although it is known by lots of different names. 

We followed the scientific method below so that we could think like scientists.

Here is Sophia's completed scientific method.

Here are some photos of what happened when we added dishwashing liquid to the milk and food colouring. When we added the dishwashing liquid the food colouring started moving all by itself and made really cool patterns. 

Have you done this experiment before? What happened when you did it?
