 On October 1, 2014, Pre-AP Science, AP Biology, ACE students, and Peer Helpers were inspired at a motivational talk by Dr. Charles Bolden, NASA Administrator and retired astronaut at the Ontario Science Centre.

Dr. Bolden informed our students of current NASA initiatives, including searching for answers to the questions, "How did human beings get here?" and "Are we alone in the universe?"

Dr. Bolden also spoke of the value of continued perseverance for overcoming challenges in life in the pursuit of achieving goals and dreams. Dr. Bolden, in the words of Nkosi Johnson, an inspiring, underprivileged youth, encouraged Thomson students to "do all you can, with what you have, in the time that you have in the place you are".
