SPRING INTO NATURE SKETCHING – Spring is the perfect time to grab your sketchbook and get outside to look more closely at the new life bursting out around you. Sketch along with Jean Mackay, author and illustrator of The Nature Explorer’s Sketchbook, for a fun exploration of spring things, colors, and patterns. Jean will share activities and tips to get you ready to head outside this spring.

Bring paper and a pencil, colored pencils, crayons, or markers to this session. Jean will share nature objects to sketch or your can bring your own. This session is especially suited to the 8+ old artist, explorer or nature lover in your world (and adults who have wanted to try nature journaling).

Artist and educator Jean Mackay has been exploring and sketching nature for more than 25 years. Working in all kinds of settings, from tide pools to farm fields to her own backyard in Upstate New York, Jean’s nature journals reflect a keen eye for detail and profound sense of wonder. She teaches each summer at the Hog Island Audubon Camp in Maine.

ESCAPE GREENLAND – A few years ago, author and marine scientist Dr. Ellen Prager went to Ilulissat, Greenland for research on climate change. She spent hours hiking around the KangiaIce fjord, went kayaking among icebergs, observed the Equi Glacier calve from a boat, and discovered a mesmerizing land of icy wonder. It also inspired her for the setting of the soon-to-be-released (April 1st) second book in her Wonder List Adventure series – Escape Greenland.

Join Ellen as she introduces you to the wonders of Ilulissat, Greenland, the impacts there of climate change, and as she gives you a glimpse into the fun and exciting adventures of Ezzy and Luke Skylar in the new book.

  • See and learn about the astonishing Kangia Icefjord, possibly the world’s most prolific producer of icebergs (including one very famous one).
  • Learn how whales, seals, and native Greenland dogs come into the story, and how Ezzy and Luke must deal with bullying and make decisions that could have dangerous consequences.
  • Hear about how in this tale, cold-water kayaking takes on a whole new meaning.

Ellen will share incredible images of the setting and explain why she chose it. She will also preview the Real vs Made-up section of the book to see if audience members can tell which parts of the story are based on real science and which are pure fiction.

So come join us for some frozen fun!
