Rachel's experiments

On Monday last week Rachel did lots of experiments with us.

In this jar was oil, maple syrup, hot red water, cold blue water and ice.  The ice sunk under the oil and none of them mixed. 

We put the blue cold water on top of the red hot water. It made purple because the blue water sunk down and mixed. It did not work the  other way round.

Thanks for doing science with us Rachel.
