This week there has been teachers from different schools coming to Holywood and our teachers have been going to other schools such as Lincluden, North west community campus and Shawhead. P5-7 have had a science lesson with two teachers from two different schools, the science lesson was about a dessert island dilemma. What we had to do was to get contaminated water and try and filter the water with products such as sand, cotton wool , gravel and a sock, then test each of the products separately in four different beakers to see which one cleared more. Once we finished we would get tested from the teachers to make sure it is fair ( fair means that everything has to be done the same with an average volume in each beaker ) . If we have finished all of this we were aloud to multi-layer the products together to see if the water would filter easier.
