Brains On! Science podcast for kids

There are many different types of snow. From the fluffy to the slushy, this slippery frozen stuff comes in all different shapes and sizes. From a distance, snowflakes may all look the same, but they are not. In fact, there are lots of different shapes of snowflakes — not just those classic shapes you might try to replicate with paper cut-outs.In this episode, Dr. Ken Libbrecht answers all of our snowflake questions: How are snowflakes made? Why are they different shapes? How is it that they’re all unique? And how does a scientist who lives in southern California study snow? And, he also lets us in on his brush with a couple Arendelle princesses.Plus our pal Ruby Guthrie pays her local ski slope to visit a snow-making machine called “Kevin.” And of course, there’s a new Mystery Sound to warm your ears.If you’re looking for some fun snowflake activities to do at home, Ken’s provided this great list — and you don’t need to live in a cold climate for all of them: http://www.snowcrystals.com/activities/activities.html This episode was sponsored by:Shopify (Shopify.com/brainson)Indeed (Indeed.com/BRAINSON)Interlochen Center for the Arts (Interlochen.org/brainson)See omnystudio.com/listener for privacy information.
