Brainstorming, Scytales and Straw Bridges

Here are some of the things that we did... This Week In Gifted!

Brainstorming

This week all of the students in grades 3 to 5 brainstormed topics to research under the broad heading of communication.  We started out with each class as a group suggesting topics. 

Communication Research Topic Ideas

Then students worked individually or in pairs; writing topic ideas on post-it notes and sticking them onto large sheets of paper.  Using post-it notes meant that if a student wrote down an idea and wasn't happy with it (either the idea, or that it was misspelled or messy) they could just discard it.  Handy for those perfectionists in the group.  It also meant that they could move ideas around on their page and group similar ideas together. 

Post-it note brainstorm

We talked about the DOVE principal of brainstorming:

D--Defer judgement

O--Oddball or outrageous ideas encouraged

V--Vast number of ideas

E--Expand or elaborate on ideas

The hardest DOVE principal for most students is deferring judgement.  We talked about how the key is to start getting ideas down.  Because one idea often leads to another, and another.  Eventually you end up with an idea that really strikes your fancy!  At times in the brainstorming process we stopped and looked at the ideas others were coming up with.  The ideas we liked, we borrowed, or they made us think of new ideas.

After brainstorming, some of the classes were able to start researching the communication topic in which they were most interested.  All of the grade 3, 4 and 5s will be spending time more time on this research in upcoming classes.

Scytales

What is a scytale?  Ask our grade 1 & 2 Wednesday afternoon class!  We continued our exploration of steganography (hidden messages) by creating our own scytales.  Scytales have been in use since at least the 7th century.  A message is encrypted by wrapping a strip of paper (parchment or leather were used in earlier times) around a cylinder.  The message is then written on the paper.  When the paper is unwound, it just looks like a random collection of letters.  To decipher the message, it must be wound around a cylinder of the same diameter as was used originally.  We used long strips of paper and wound them around some wooden cylinders.  At home you could use cardboard tubes from paper towel rolls or wrapping paper rolls.

Straw Bridge Challenge

The Summerland ASPIRE class did the Straw Bridge Challenge.  Last week they were given the instructions for this challenge, but they were encrypted.  Students had to use their code breaking savvy to decrypt the instructions.  This week it was time to do the challenge.  Each small group of students were given 

• 15 thin drinking straws
• 25 cm of masking tape
• 1 pair of scissors

The goal was to make a bridge that spanned a 30 cm gap and was strong enough to support a coffee can.  The can could be rested on the top of the bridge, or suspended below the bridge using string.  The next part of the challenge was to see how many golf balls could be placed in the coffee can before the bridge collapsed.  

This activity encouraged students to think creatively.  They also had to be able to communicate well with their partner(s).  Below are photos of some of the bridges as they were being built:

 

The photos above show three very different approaches to the bridge structure.  The top bridge was the strongest; holding the coffee can and 2 golf balls.

Non-Verbal Communication

Finally, all of the classes have been looking at non-verbal communication.  Whether it is by playing Charades / Funny Faces or by acting out a narrative walk.  So beware; the students are becoming skilled at interpreting the non-verbal signs we all transmit! 

Thanks for checking in to see what we've been up to!
