ZOOM to Galaxies, Planets & Black Holes – 9/24 – 5:00 pm ET – FREE

Dr. Grant Tremblay and Katie Coppens are tackling the toughest space questions that you might have in this fun session. Dr. Tremblay is an astrophysicist at Harvard and the Smithsonian and is one of the hosts of various TV shows including “How the Universe Works” and “Space’s Deepest Secrets.” In this session, space facts from the mind of an astrophysicist will be brought down to earth by Katie Coppens, an award winning middle school teacher.

The authors will start with questions from their popular book What Do Black Holes Eat for Dinner?

  • Haven’t you always wanted to know what would happen to a spider in space?
  • Are there clouds in space similar to earth?
  • Is it true it rains diamonds in space?

Then they will follow up with questions from contest winners who submitted their own silly, yet totally smart, questions about space. Those attending this session will also have the opportunity to ask questions!

Submit your best space questions in advance and Grant and Katie will answer three of them live. The lucky winners will receive a copy of What Do Black Holes Eat for Dinner?. Enter your questions by 9/16 when you register. Please include your first name and the state where you live with your questions.


Audience:  for ages 9+

Date:  September 24, 2020

Time:  5:00 pm to 5:45 pm ET

ZOOM with The Puffins Off The Coast of Maine – 10/7 – 5:00 pm ET – FREE

Fifty years ago, a young ornithologist named Steve Kress fell in love with puffins. After learning that hunting had nearly eradicated their colonies in the 1880s off small, rocky islands in Maine, he resolved to bring them back. In 1973, he began collecting chicks in Canada, flying them to Maine, raising them in coffee-can nests, transporting them to their new island home, watching over them as they grew, and then waiting—for years—to see if they would come back. From 2 birds left in the entire state in 1902, there are now more than 1,300 pairs of puffins on Maine islands. In this session you will learn how Kress’s quest, today called Project Puffin, became one of the world’s biggest conservation victories.

Co-author Derrick Z. Jackson has documented the success of Project Puffin with close and personal puffin photos, which he will share in this special event. As a finalist for the Pulitzer Prize, as well as numerous other awards for both his writing and photography, Derrick has an impressive array of photographic experience to share.

Steve and Derrick will frame this session around their new book, The Puffin Plan – Restoring Seabirds to Egg Rock and Beyond. Come prepared to fall even more in love with these endearing creatures, be awed by how they thrive in their natural habitat, and learn how the Puffin Project reclaimed a piece of our rich biological heritage.  Maybe you will be inspired, like others around the world, to help animals return to their native habitats.

ZOOM To Antarctica To See The Adelie Penguins – October 21 – 5:00 pm ET – FREE

Adélie Penguins exist only in Antarctica. The daily life of these penguins is filled with adventure and drama, as they struggle to live and thrive in the challenging environment and changing climate of the frozen south. Author and penguin researcher Jean Pennycook lives for two and one half months every year camped near the Adélie Penguin colony at Cape Royds, Antarctica.

She has studied the behavior of the penguins as they come ashore, build nests, lay eggs, and raise their chicks for 15 years. Covid has restricted travel to Antarctica this season so Jean is working to educate others about what her science team is learning about the penguins, and how changes in their environment are effecting the lives of these remarkable birds.

Ever wonder how penguins survive in Antarctica? How are they adapting to climate change? What is it like to live and work in the penguin field station at Cape Royds? Jean will discuss 15 years of observations and trace the story of one penguin she calls Joey. You will hear about Joey and Jean’s adventures as they develop their skills in surviving this harsh environment. She will share her photos, videos, and stories from the research station in Antarctica as well as from her book Waiting for Joey.

Submit your best penguin questions in advance and Jean will answer three of them live. The lucky winners will receive a copy of Waiting for Joey. Enter your questions by 10/14 when you register. Please include your first name and the state where you live with your questions.


Audience: for ages 8+

ZOOM for All Artists, Explorers & Nature Lovers: LOOK – SEE – SKETCH –  11/4 – 5:00 pm ET – FREE 

Now, more than ever, exploring close to home is a way to turn the small and modest into the infinite and boundless. The Nature Explorer’s Sketchbook helps kids look more closely at nature and capture what they discover. If you like exploring nature or drawing or both, this session is for you! Meet the author, Jean Mackay, ask questions, and draw along with Jean as she shares some activities and tips from the book to spark your curiosity.

Bring paper and a pencil, colored pencils, pens, or markers to this session, along with an object from nature (e.g., leaf, rock, mushroom, flower, seeds, shells, etc.). This session is especially suited to the 10+ 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.

ZOOM To Help Save Endangered Animals – 11/18 –  5 pm ET – FREE

The earth is inhabited by the tiniest of organisms, including dreaded viruses, and the largest animals that sit at the top of the food chain. What they have in common is their interconnectedness and the risk of extinction. Species endangerment:

  • Where is it happening?
  • Why is it happening?
  • What can be done?

Eva J.Pell will be your guide. She is an internationally known plant biologist, former Undersecretary for Science at the Smithsonian, and author of ResQ Takes on the Takhiand ResQ and the Baby Orangutan – adventure novels for middle grade about rescuing endangered species. In this session she will engage the audience with an interactive game which will be the jumping off point to talk about endangered species:

  • their biology
  • their natural history
  • why they are in peril

Eva will use her ResQ series as a point of reference about species endangerment. The presentation will be interactive, with participation/questions encouraged throughout. Come help Eva spread the word and work on how to protect our world order from species extinction.


Audience:  for ages 9+
