Investigating Floating and Sinking

 “I was testing -we did loads of experiments in case we missed a part of it… we were seeing if things stayed up or down.” said Eden. The children also had the opportunity to consider different measuring methods using paper clips or bricks to compare the length of objects, using string to measure the circumference of their heads and make comparisons. The children experimented with volume counting how many lids of water it took to fill a selection of containers.

Dry Ice Experiments

On Friday afternoon one of our parents Taciana Kasciukovic from Dundee University discussed with the children the difference between solids, liquids and gases. The children were able to see experiments with dry ice. When the ice in a small test tube melted and turn in to a gas it caused the test tube to explode and “pop”. When the ice was placed in soapy water the solid ice changed in to a gas and caused the foam to over flow from the basin. In the final experiment gas filled a balloon and the children waited with great anticipation in the hope that there would be another explosion!
