In preparation for Science week, Year 6 began their investigation in to how to make the perfect slime and whether it was classified as a solid or a liquid.
First the children reviewed the definitions of solids, liquids and gases. The children then looked at pre-made slime to grasp an idea of the correct consistency.
The task was then for the children to use the ingredients (cornflour and water) and decide on the measurements. Once the children had tested their original measurements, they were then able to add more and tweak if needed.
The children concluded that the perfect slime was achieved if that the slime moved like a liquid but became solid like with added pressure (squeezed or pressed).
As part of the experiments week, the children investigated which substances were acids and alkalis by using blue and red litmus paper.
They then looked at the effect of acids when mixed with other substances. The outcome can be seen below.
