On Friday 28th October, Mrs Inzitari and four year 10 5.3 students ventured across to Bicentennial Park for a Mathematics in Surveying Excursion. The day was run by volunteer surveyors and students from the University of NSW. It allowed to students to gain an insight into the profession of surveying and the many avenues available for them to study and work. The day began with a brief history of surveying followed by a demonstration of a lawn-mower looking apparatus called a Ground Penetrating Radar. The boys were able to trial this piece of $30 000 equipment in order to see if there were any pipes or wires under the ground. We were all very impressed with how mathematicians have created this technology for use in today’s fast paced world. Other activities included using trigonometry to find the bearing of a bushfire from a viewing tower, and finding the exact heights of structures using different types of surveying equipment and lots of mathematics. Overall, the students appreciated the chance to be part of this day, as it brought their mathematics lessons to life and gave them a pathway to exploring surveying as a career option after school. A special thanks to the boys for being so well presented and involved on the day. The head surveyer and organiser was very impressed with the high quality of students representing St Francis Catholic College.
