As part of Science week and our IDL topic the children have been exploring how to make and test predictions about solids dissolving in water.
Experiment one involved the children to predict, investigate and record how solubility is affected by heat and stirring. The children had to predict which method would dissolve the sugar the quickest and why. We looked at this through using cold water, warm water, warm water stirred or cold water stirred. The children all worked in groups and discovered that the warm stirred water was the quickest because when water is heated and stirred, the molecules gain energy and thus, move faster.
To follow this experiment we also did the Skittle Experiment and the children loved learning that warm water dissolves the food colouring on the sweets and makes beautiful rainbow patterns. The children all had good fun and enjoyed being Scientists.
