How? Look through the slides to learn about codes and the Caesar Cipher! Watch Nanogirl's video to learn how to make your own cipher wheel.
Reflect: If you lost your cipher wheel or forgot the key, how could you decode the message? For example, which letters and words do you think you would see most often?
Write out a coded message then give your cipher wheel to someone else. How fast can they decode your message once you give them the key?
How could you disguise or hide your secret message so that no-one else can find it?
Share: Share a photo of your cipher wheel on the Science padlet. Maybe you could include a coded message and challenge other people on the padlet to solve it!
