This term Room 11 have been doing some science experiments. We have done an experiment with milk, a lava lamp, a quick sand experiment and one on surface tension where we made paper clips float. If you put a paper clip in water it will sink but we made them float. First we ripped some tissue paper and put it in the water and then placed the paper clip on top. The tissue paper floated. Now the idea is to get the paper clip to float on the surface – it was quite hard but we did it. You have to carefully remove the tissue paper. The science behind this is that the paper clips are held up by the surface tension of the water.
