We continued with our theme from last week ‘Ada Twist Scientist’ and have encouraged the children to experiment with oil, coloured water, vinegar and baking soda. The children mixed the oil and water and observed that the substances did not mix. The vinegar and baking soda experiments gave the children a surprise. They discovered that they have a strong reaction when mixed together – an explosion. The children had a most enjoyable time asking lots of questions and most of all having fun.
