We love snow. When we lived in Central Oregon – we were delighted with each snowfall. Living now in Northern California, we don’t get to enjoy as often. Mount Shasta is just far enough away that it would be a full day outing if we desired to go skiing whereas Mount Bachelor was near enough, we could go for just a few hours and still have time enough in the day for other errands or activities. The first year we lived here, sadly, there was very little snowfall – even at Shasta.

When the snow fell this week – we were both delighted and heartbroken. My father, brother, and sister-in-law were planning to drive down to spend the weekend with us for Christmas. I-5 was closed off and on all through the end of the week and through the weekend. Even with chains, the delays and closures forced them to stay home. As a small consolation, the kids and I chose to curl up with a few holiday books and do a little nature study to take advantage of the snow fall which coordinated perfectly with the Outdoor Hour Winter Snowflake Challenge.
One of the books we read was Snowflake Bentley by Jacqueline Briggs Martin. We’ve read it before but I learned that Buddy didn’t remember it so it was a new discovery for him (not surprising when you read my previous post and discover what what he was focused on that day). Winner of the 1999 Caldecott Medal, it tells the story of Wilson Bentley.
From the time he as a small boy, he saw snowflakes as tiny miracles and was determined to capture these small wonders on film. His work and dedication revealed two things – no two snowflakes are alike and each one is based on a six-pointed crystal.
After the story, we watched a Brain-Pop video on snowflakes and googled snowflake images. We had wanted to capture a few flakes to observe under the microscope, but it had stopped snowing by now and the snow on the ground was wet, melting off by early afternoon. We noted, therefore, that we had an easier time illustrating snowflakes than Bentley would have.
We recorded in our journal that since the angle that the individual atoms in water form is 104°, ice freezes into a roughly hexagonal molecular lattice. This six-sided crystalline shape is reflected into the snowflake’s overall shape, causing snowflakes to have a 6-fold symmetry. Here is a fun video from Khan Academy to help illustrate this fact, Snowflakes, Starflakes, and Swirlflakes.
Our nature journal entries … sadly, the image is not very clear.
Coincidentally, we had created numerous paper snowflakes earlier in the week to send to Sandy Hook Elementary School. Members of the school PTA are coordinating an effort to convert the new school students and staff of Sandy Hook will be housed in after the holiday break into a winter wonderland.
I love that as unschoolers, we were able to “seize the moment” and thoroughly integrate our curricular studies: nature, science, writing, literature, biography, math, art, and service learning. It was indeed a full day of learning but took only an hour or so of actual clock time.
