We have been doing some fun experiments in our classroom, learning about mixtures.

Mrs Allen demonstrated an experiment using colour, oil and water. We wanted to see if the water or oil was heavier. What would happen if we put dye/water mixture on top of oil. Would it stay or sink and dissolve in the oil.

First we added water to our container.

Then we put oil  into a separate cup and Mrs Allen then dropped in some colour. 

She slowly added the mixture to the water. We had to use our Science skills to notice what happened.

The oil and colour stayed on top of the water at first.

Then the colour slowly started to sink through the oil.

When it hit the water it looked like it was exploding. The colour was dissolving into the water. It looked like Fireworks going off in the water.

We enjoyed watching how the colour slowly dissolved. We learnt that dye dissolves in water, that oil floats on water and that water is heavier that oil.
