Snowy Science Storms Kindergarten

by Steve Lechner (Lower Division Science Specialist)
I started my “Snowy Science” unit with the kindergarteners last week by reading The Snowy Day, followed by showing the students my snow collection, which they had to sort and classify to find the reason why NONE of my samples were actually real snow. I then discussed the concept that snowflakes have six sides or points, and we looked at different shapes to compare and contrast them. I finished up by showing them my snowman that I made last year and kept in my closet all year (he was just water with a hat, scarf, eyes and a carrot nose in it). The students helped me figure out the best place to keep a snowman.
This week we followed up by talking about ice, and demonstrating how warm air will melt ice cubes slowly but their warm hands with melt it really quickly! I then told the students about how I used to be a cowboy, and learned how to ride around in the desert lassoing ice cubes. I made a very tiny lasso and attempted to lasso a very large ice cube (which didn’t work). Eventually I remembered my secret ingredient (salt), which when sprinkled on the ice lowers the freezing point of the ice, allowing the lasso freeze onto the ice cube! Check out a video of this experiment!
