Today’s Wonder Wednesday was – literally – super cool! We listened to an episode of Radiolab centered around intriguing anecdote: on the Russian-Finnish border during World War II, hundreds of horses fled a forest fire and stampeded into Lake Ladoga. The lake was very cold but not yet frozen, and – according to legend – as soon as the horses entered the water, it froze instantly, trapping them all.
The scientific concept behind this story is called super cooling: pure water that is very cold but not yet frozen will freeze instantly when it comes into contact with something such as dust, bacteria… or maybe horses?
We ran out of time and were unable to finish the podcast so here is a link in case you want to listen to the whole thing again: Radiolab: Super Cool
During the podcast we also watched this video from Grant Thompson, aka “The King of Random”:
What do you think? Did the horses really cause the lake to freeze?
In the lead-up to this year’s Wonder Expo, the Grade 7 boys enjoy a “Wonder Wednesday” every week in order to build curiosity and excitement about the world around them.
Today’s theme was hexaflexagons! I’m pretty sure this is going to be a big hit because the boys were so fascinated and excited by the idea. Here are the two videos we watched:
And here is a tutorial if you’re keen to make your own!

Grade 7s hard at work in the “explore” stage of guided inquiry.
It has been an exhausting but satisfying fist week back at school. The Library is all set up for the new school year, with tons of new books and a few new systems in place.
The self-serve kiosks are set up and ready to go, meaning the boys can now check out their own books, and leaving Ms. Walker free to herd cats:
We’ve also implemented a “Clean Sweep” system to ensure the library gets tidied up after each class visit:
And, most exciting of all, we now have a microphone for making announcements! It has clearly gone to someone’s head:
The Grade 7 Socials classes have also begun working on a guided inquiry unit for Remembrance Day. We held an “open” session this week in the library, with the boys reading war-themed picture books:

Phew. That’s a lot going on, but we’re really looking forward to the year ahead. Time for curiosity, creativity and fun!
#EarthWeek2015 was a success! The school was full of natural light, there was minimal garbage and Green Shirt Day was inspiring. We had a record number of students walking, biking and carpooling to school. Thank you for your support 🙂
We’ve begun adding digital audiobooks to our library collection! Currently we only have a handful – mainly novels the boys study in Language Arts – but we will continue to build the collection as demand dictates.
If you are in Grade 6 or 7 and would like to try one of these digital audiobooks, the instructions can be found here
