As the Clocks arc moves right along, we see different rhythms emerge in each band – some continue exploration of gears and timers while others move into project phase with experts and declarations. A quick overview on this Friday evening:
The Megaband has started to write declarations for Clocks projects and get them approved by Gever, who has a brand new stamp for the official ‘OK!’. Sean helps Jack with a piece of his declaration.
Josh hosted baker Jasmine as an expert for his baking project.
A glimpse of Alexander of the Long Now Foundation during his presentation last week:
Mackenzie started exploring gear ratios with the Hawks this week and was able to incorporate learning about least common factors and multiplication families through a provocation that asked how many revolutions that gears with different numbers of teeth would need to make to return to the starting position.
The Hawks and the Elephants also continued their explorations of water clocks. The Hawks returned to the previous week’s discoveries to make new iterations of their water clocks. (More information on their results soon!)
Isaac, Max, and Madison created a gear chain under Sean’s tutelage that reduces every 3600 revolutions of the input gear to one revolution of the output gear. It’s same ratio of seconds to hours, which is the same relationship as a second hand to the hour hand. They had to plan out how to combine the different gears and assemble the whole thing themselves.
The Hummingbirds have been working with 15-second timers this week – Shawna wrote an amazing piece about their process, which I will write about next week – and used 15 as a provocation for exploring sets of five.
And bonus: we had a visit from Santa and his crew today. It was unfortunate that Clementine, Lola, Aurora, and Natasha had to miss it.
