Snowflakes are actually very mathematical!
Our goal today was that the students would be able to generate geometric definitions using critical attributes of a 2-dimensional figure.
We began by reading the book:
After reading the story, I showed a short video about Snowflake Bentley that showcases the photographs he began taking in the early 20th century. The images are pretty amazing!
Finally, we began to focus on the geometry of snowflakes by working with the fact that most snowflakes are hexagonal. We defined a hexagon by using its critical attributes (sides, vertices, angles, lines of symmetry, parallel, etc.), then we folded the hexagon on a line of symmetry and created a trapezoid. Next, we defined the trapezoid using its critical attributes, then folded the trapezoid to make a rhombus, and finally created an equilateral triangle, each time defining the 2-d shape using its critical attributes. I made a video of the notes that we began today entitled Snowflake Geometry.
