I really like the idea of linking O's daily advent book with her daily advent activity, and Snowflake Bentley was the perfect book with which to start this new tradition. After reading the book, O, Elliott, and I made a crystallized snowflake ornament.
First, I made the snowflake using a white pipe cleaner. Then Elliott took over while I nursed and rocked the baby. He helped O measure and pour 4 and a half tablespoons of borax into a glass bowl. He then boiled a cup and a half of water in the microwave and poured it in the glass bowl and stirred. O put blue food coloring in the mixture. Elliott put a jar lid at the bottom of the bowl and balanced the snowflake on top of the lid. (Use 3 tablespoons of borax for every cup of boiling water. Our container needed 1.5 cups of water to completely cover the snowflake, so we used 4.5 tablespoons of borax.)
We let it sit for 24 hours before removing the snowflake from the water. We were all very impressed with our beautiful snowflake ornament, and I think we'll make more of these to give as gifts.
This was a great activity that combined arts and crafts, science, and fun!
