We investigated materials to find out which ones were waterproof or non-absorbent.
We took two sugar cubes and a tray of coloured water.
We put one sugar cube into the water and it absorbed the water straight away.
We put a piece of material on top of the first sugar cube and then another sugar cube on top of that. If the water travelled through the second cube, we knew that it was an absorbent material.
It the water didn’t travel through the second cube, we knew it was a waterproof material.
We discovered the kitchen towel was most absorbent and the plastic and the foil were most waterproof.
Now we want to know if a material can be both waterproof and absorbent.
