We were all very excited when our Chemistry teacher told us that we could participate in the NSTF Science Days in Gozo. Our teacher suggested that we could work on a project about nurdles. When we researched the topic, we discovered that nurdles are what plastic looks like before it is moulded into familiar objects. Due to shipping mishaps, nurdles are usually found floating on the oceans where they are ingested by marine organisms causing them harm and they also land on our beaches causing pollution.
We went to Ramla Bay to find evidence of these nurdles and to our dismay we realised how polluted the sand was. We decided that there is a solution to this problem and so we designed an experiment to separate the nurdles from the sand by simply adding water to the mixture. The nurdles float on the water while sand sinks. This makes it easy to remove the nurdles from the sand.
Thanks to NSTF, not only did we learn from our project, but also from other students’ work that was being exhibited. It was an amazing learning experience and we are looking forward to participate next year.
