No Two Snowflakes Are Alike?
We will read "Snowflake Bentley" and talk about it. I am hoping to steer the conversation toward the shape and designs of snowflakes. We will research snowflake designs using the Internet and a few books I have collected. The final assessment will be the students' original designs, and I will be looking for symmetry and originality.
Context for Use

-Other snowflake identification books or resources such as "Snowflakes in Photographs" by W.A. Bentley and "Easy to Make Decorative Paper Snowflakes"

Description and Teaching Materials
Day Two: Students will capture some snowflake prints themselves. Using the transparency film, cut into credit card-size pieces. Spray the cold Krylon clear acrylic on the film and have students try to catch a snowflake on the sticky film. This is not easy. The day needs to be fairly quiet, snowing, and cold. Once they have a snowflake on their film, it needs to dry outside. I want to hang ours outside the classroom window on a small clothesline, using clothespins. They will dry slowly. Not all the samples will make visible prints, but then neither did Mr. Bentley's.
Day Three: Students will draw their own snowflakes using graph paper, rulers, and compasses. They can follow basic designs that were studied and then add a new part to make it original or make a completely new design. Hang or display these in the classroom or hallway for others to admire. Attach a student written summary of the process used to learn about snowflakes, to the drawings.
Teaching Notes and Tips
2. Inquiry: students will research and observe snowflakes and extend this lesson into math, science, and art.
