Communication Research

Here are a few of the things we've been doing this week (and last!) in gifted.

Deciphering

Last week the grade 4s and 5s learned how to encipher and decipher keyword ciphers.  They used letter frequencies to decipher keyword ciphers when the keyword and keyletter were unknown to them -- a pretty challenging task!  They then put these skills to work playing the game Rogue Computer.  

My favourite student quote last week came from a student in the grade 2/3 afternoon class.  The students were working on deciphering Caesar Ciphers in order to solve the clues in the game Desert Oasis.  It's pretty challenging work when you don't know what the shift is and have to use letter frequencies.  To no one in particular a student said, "This is hard!"  I waited and watched.  "This is hard!"  Again, I waited and watched to see if the student was hitting his limit and needed intervention before frustration took over.  "This is HARD... but it is so much FUN!"  Yes!

This week the students were introduced to a new cipher -- the Pig-Pen.  They were able to decipher the message on the board in short order!

Body Spell

This week the Wednesday morning class played the game Body Spell.  Students were in two teams and each student had letters drawn on their hands and feet.  They were then given a word that they had to spell with the letters on their body -- crazy!  They handled the small 4 and 5 letters words quite well and easily progressed to the 7 letter word they are spelling in the photo below (the letter on the sideways foot is a 'T').


Communication Mini-Research Projects

This week all of the classes started doing research on topics related to communication.  These will be small projects just to whet everyone's appetite before we get into our bigger radio project.  Some of the topics students are investigating are: hieroglyphics, the Rosetta Stone, the Enigma Machine, American Sign Language, Braille, Morse Code, the telegraph, the history of emoticons/emojis, communication in different types of animals (bees, seals, whales...), codes used in WWII, computer coding... It's going to be fun sharing what everyone has learned!

Halloween

Here are a few of the things that we did this past week in Gifted.

Snap Circuits

The Tuesday afternoon group at Trout Creek is enjoying building more complex circuits with our Snap Circuits kit during social time.


This circuit uses a solar cell, resistors, a simple LED, a 7 segment LED display, motor, speaker, resistors...

Keyword Ciphers

The Tuesday group also learned how to encipher and decipher messages with the keyword cipher.  The rest of the groups will be spending time on that this week.

Halloweeen Hijinx

The usual students did not show up for the Wednesday (Halloween) classes.  Instead there was Minnie Mouse, a cowgirl on a horse, a grim reaper, a dark fairy, a demon (sorry Skyler -- I couldn't remember the full name!), the Childlike Empress, Spider Girl, and a mummy.  Yikes!  Also, Julius Caesar took over teaching the class (he does know a lot about Caesar Ciphers after all.)

Love those creepy fingers!

Field Recorders and Movies

In preparation for our radio project, the Wednesday morning group learned how to use the three H1 Zoom recorders that we have as well as a voice recorder on the mini-iPad.  These are all portable audio recorders.  Students experimented with interviewing each other and getting a sense of how far away to hold the recorders from their mouths.  All of the classes will be getting a chance to work with the field recorders in the weeks ahead.

In addition, the morning class made a short silent movie.  The Dark Fairy (aka Sage) suggested making the movie since we had all of these characters in their amazing costumes.  It was a collaborative effort and came together really well!
