| My name is Kayleigh Ng. I am a 13 years old, 7th grader attending The St. Lawrence Christian Academy in Brockville, Ontario. I play the recorder and love singing in the choir. I also enjoy playing sports at school such as track and field and soccer. My hobbies include cooking, boating, painting, playing the ukulele, four wheeling, traveling, and shopping. I won in my very first duathlon and my soccer team has won the league championship the last 2 seasons. I was very excited to have won Best of Fair- Junior at the Rideau St. Lawrence Regional Science Fair this year. This is my first time attending the Canada Wide Science Fair. |
