The digital environment is a place where persons can share any type of information they wish – pictures, personal anecdotes, credit card information, names of family members, favorite places to visit, etc. The more information shared, the more important it becomes to protect this information from unauthorized access. This unit will help students explore why codes are important, how they function, and ways to make them as effective as possible. Students will practice writing their own codes using multiple strategies from handwritten notes, to mazes designed to keep robots out, to a two-step authentication scavenger hunt.
