All month long we have been discussing Spy Codes and trying out Spy Gear. These spy-savvy kids have gotten really good at deciphering codes, and even making up their own codes. So clever!
This week, we learned about the Navajo Code Talkers dictionary that was so complex that expert code breakers could never decipher it. During WWII, The Japanese managed to intercept messages from the U.S. Army and the Air Corps, but they were never able to figure out what the Marines were telling one another. Were it not for the Navajos, the Marines would never had taken Iwo Jima.
We found it interesting to learn that the Navajo Code Talkers were so valuable, that each one was assigned their own personal Marine to guard them, to keep them alive and prevent capture.
In studying the Navajo Code Talkers dictionary, we giggled at the literal translations. Here are some of our favorites:
Dive Bomber = Chicken Hawk
Bomb = Eggs
Grenade = Potatoes
Tank = Tortoise
Sniper = Pick 'em off
Scout = Short Raccoon
Submarine = Iron Fish
America = Our Mother
The next code we learned about was Morse Code. Each kid was handed a rice crispy "bomb" that contained a secret morse message hidden inside. We had to nibble and munch to get to it. While we nibbled, Teacher Melissa shared a fun fact about Morse letter "V" ( ...- ). Officers played Beethoven's Fifth Symphony to rally troops on D-Day. The opening notes create the "dit dit dit dat" that represented "V" for "Victory"

How to Be a Spy
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.
