This month, we are starting a new unit. All about Spies!
We briefly talked about what it takes to be a spy, and focused on Cryptography: Secret Codes and Decoding.
We introduced the Pig Pen code, and had a ball creating and deciphering secret messages! Don't be surprised if a secret message shows up at your house, too.
Next, we tested invisible inks. Lemon juice and milk make great ink for secret messages! Only real spies know that to reveal the secret message, you must expose the paper to heat. (like a candle flame or stove burner) and when that happens, the message magically appears!
It was revealed to me that we have several Spy-Savvy students in our class...I encouraged them to share their knowledge with us and prepare something to share with the rest of us in future classes. They are welcome to demonstrate different codes or ciphers, spy stories/history or spy gadgets. If you have one of these smarty-pants spies at your house, please let me know if there are any supplies that I can help you gather, or any other support that you require.
