Students Create their own Cryptography Wheel!

Students in Ms. Holly Swain’s Grade 4 class at St. Charles Elementary School created their own cryptography wheel and became cryptographers solving mystery messages all afternoon! 

Nicholas Butt, Outreach Coordinator for Let’s Talk Science and special guest Morgan, first year Master’s Student in Neuroscience at University of British Columbia led the students in this week’s STEM activity.  Students gained an understanding about the history of cryptography and how ancient Greeks were known to have ciphers over 2000 years ago. Students also learned that  computer science uses cryptography  to secure information and communication techniques using algorithms to transform messages in ways that are hard to decipher.

There is still time to Register Your Class  for fun and interactive STEM activities intended for Grade 4-6 students! Each week, Let’s Talk Science, features a different hands-on activity using minimal, easy-to-find materials.  Students will also have the chance to learn from and ask questions to inspiring STEM role models. 

An English activity is offered two times per week (Tuesdays at 11:30 a.m. ET & Wednesdays at 1:00 p.m. ET), and a French activity is offered once a week (Tuesdays at 1:00 p.m. ET).

The third cohort starts on January 27th 2022. For more information visit: Join the Let’s Talk Science STEM club or contact if you would like more details about participating in this activity.
