On Monday the second of March Holywood seniors produced there own experiment! The students worked in partners of two, each pair had a bottle of dirty water that they had to attempt at purifying. The students had three different materials such as… One Pop Sock, Gravel, Cotton And lastly One handful of sand. Using the materials they had, they tested each one of there materials individually and fairly. in conclusion most students believed that cotton proved more useful in this situation, although a small group of students thought that the pop socks were even better. Near the end of the experiment the students tested some of the materials together, the cotton and pop socks seemed more useful than the rest!
