The pupils of 4th/5th celebrated Engineers Week 2019 by meeting a fully fledged and highly skilled scientist. A huge thanks to Sinéad Ryan and Walter Messina from the Tyndall National Institute (U.C.C). Walter, a postdoctoral researcher with the biomedical department in Tyndall spoke to the class about his background in military engineering where he has designed robotics. He also spoke to the children about his most recent work in biomedical engineering. The children thoroughly enjoyed the experience because Walter showed the children some micro-chips that he has used in some of his projects. He also brought some resources from Tyndall to conduct two experiments with the pupils. The first experiment involved the use of 3-D printed lego pieces some of which were irregular so a lot of planning was required before attempting to create the miniature-duck. Walter explained that planning is a key component of any project he works on. The students had to design their tallest bridge using sketch-paper before working in teams to build the tallest tower out of straws. Many thanks again to the Tyndall National Institute for facilitating what was a memorable day for the pupils of Bishop Murphy Memorial School. Many thanks to Walter for putting together such an engaging, educational and fun lesson for the pupils.
