“When a snowflake melted, that design was forever lost. Just that much beauty was gone, without leaving any record behind.” W.A. Bentley, 1925
Snow is magical, renewing our sense of wonder, transforming a barren landscape into a winter wonderland, and drawing us outdoors. When we look closely at falling snow, we marvel at the beauty of snowflakes. Each snow crystal is a unique, ephemeral work of art – yet its symmetrical, harmoniously balanced design is not random but created through a combination of physics, math, and chemistry. Continue reading Snowflakes – Background
FOCUS: A snowflake’s life is one of constant change, from its trip through the sky to its resting place in the snow bank. Each one is a unique, six-sided crystal with temperature and humidity as key factors determining their shape, size, and design.
Introduction: If it’s snowing, bring the children outside with black felt squares and magnifying lenses, to catch and observe snowflakes before doing the other activities. Or, hold up some large photographs of snowflakes and ask the children some things they notice about them.
PUPPET SHOW “No Two Alike?”
Objective: To learn the conditions necessary for different snow crystal formation and compare the designs of five different snow crystals. Continue reading Snowflakes – Activities
No Two Alike?
Characters: Dust, Tiny Plate, Big Plate, Needle, Column, Capped Column, Stellar Dendrite.
Dust Here I am, a tiny speck of dust floating in a cloud of snow crystals. Yoo hoo. Hello there.
Needle What’s this? A speck of talking dust.
Why, I was once a bit of dust, too.
Dust Really? You look like ice, not dust. Continue reading Snowflakes – Puppet Show
SNOWFLAKES ALIGNMENT WITH
NEXT GENERATION SCIENCE STANDARDS
The activities in this unit help children understand the basic concepts in the Disciplinary Core Ideas listed here. You can use the following list as a guide for lesson planning. These Disciplinary Core Ideas are taken from Grade Band Endpoints in A Framework for K-12 Science Education. Additionally, our activities give children opportunities to engage in many of the Science and Engineering Practices and reflect on the Crosscutting Concepts as identified in the Next Generation Science Standards.
