Science Investigation In Science, Class 2 have been exploring materials. We carried out an investigation to test the absorbency of seven different materials. Before testing the materials we predicted what the outcome would be. We dipped the materials in water, coloured with blue paint so we could see the liquid soaking into each material. To make sure it was a ‘fair test’ we made each piece of material the same size and dipped them into the liquid at the same time, then waited 30 seconds.
