Science Club: Sniffly sneezes

In Science Club today, we have used a comparative test to investigate which material makes the best hanky as part of of CREST Award. We made predication about which materials we thought would be the most absorbent and were able to give reasons using our scientific understanding. Then we planned which equipment we would need and how we could record our results. We made the test as fair as possible in our groups by using our maths skills to cut materials to the same size and counting the number of water drops from a pipette. Our results were surprising as found different results in our groups so evaluated why this might be. We decided that the amount of water each group had chosen and size of their paper made a difference. We even discovered that the colour in paper runs out and you can see the primary colours used.
