Cosmo’s Corner: What do pinecones, snail shells, and DNA have in common? 

Meow to you all, my friends! This is Cosmo the library cat here, inviting you to a STEAM Storytime coming up at the Grand County Public Library, on Tuesday, November 28 at 6:30 p.m. In this storytime, we’ll look at a very special pattern that you can find everywhere you look, in math, science, art, and nature: the spiral!

You can see spirals in snail shells, pine cones, flowers, DNA, galaxies, and even in cats. (Have you ever seen a cat curled up for a nap, or luxuriating on its back in a sunbeam? What shape would you call that? A spiral of course. Some cats even have spirals on their coats.)

These spirals aren’t just random curly-cues scribbled on paper. Spirals follow a special pattern of numbers called the Fibonacci (Fib-o-nach-ee) sequence. These numbers explain how the spirals start very small in the middle and get bigger and bigger as they expand outwards. Another way to describe this pattern is called “the golden ratio.” 

We’ll read a story about spirals, then we’ll explore the golden ratio in art and nature. We’ll also make our own Fibonacci sequence models, and then eat them up! Delicious and educational, exactly how math should be!  

Our STEAM storytime is geared towards children ages 3 to 9 and their caregivers. This event is free and open to the public. We’ll be in the library’s large meeting room. Meow till next time!
