Science day

Floating paper clip:
At first we were challenged to make a paper clip float on water with no support, we were only provided with: a pencil (which floated), some tissue paper, a bowl, a tap and a paper clip. We were split into two groups, one with Miss Williams and one with a governor, Mrs Wilkinson. Sharing ideas amongst our group, we decided that the tissue paper needed to be placed on the water first and then we would need to remove the paper carefully from under the paper clip using the pencil. If we were successful the surface tension would keep the paper clip afloat. Here are some pictures to share our learning.

Colour of symphony:
Here we were provided with a tray of whole milk, food colouring and washing-up liquid. The task was to make different patterns by mixing various food colours and then pouring drops of washing-up liquid on top - immediately on top of the food colouring. The washing-up liquid reacted to the fat in the milk because it was trying to break it down, resulting in the various patterns we created.

Umbrella test:
We were testing different types of materials to see which was the most suitable - the material needed to be waterproof and flexible.The materials we tested were: Bubble wrap, laminated paper, a carrier bag, bag for life and tin foil. All of the materials were waterproof, however they weren't all as flexible as we originally thought. Therefore the most suitable material for the umbrella was the cost efficient, flexible, waterproof carrier bag.
