In 2nd grade we have been working on polygons and how they connect to structures. To help see the connection the kids explored various crystals, starting with salt, sugar, and baking soda. They made observations about the polygons that they saw and patterns in the structure of the crystals.
We watched a Brainpop on Snowflake crystals to see the structure and how a crystal lattice is formed. Each 2nd grader was given two hydrogens and one oxygen to build a water molecule. We placed the water molecules together to build our own crystal lattice.
This week was also the Hour of Code, the second graders attempted to go through the Frozen tutorial on Code.org, but I am sure that every other kid in the world was attempting to use the same tutorial. Gotta love Frozen. I wasn’t sure what would happen, but had my 2nd graders attempt to make a snowflake using Hopscotch…ON THEIR OWN. They surprised me, of course. Kids are amazingly uninhibited and completely willing to JUST try.
As the second graders worked on their coding, I pulled groups over to create crystal snowflakes using Borax. It was fun seeing actual crystals growing after reading and studying about them.
