VISITING IN-PERSON IS FABULOUS!

 I LOVE SCHOOL VISITS! 

to get on my 2026-2027 calendar email sandramarkle@yahoo.com

I just had the most amazing time visiting schools! I say that after every visit! 

I share a science magic show with large groups. We have a blast!  I challenge everyone to think and vote on possible outcomes for each activity. Next comes that tension-building AWESOME moment when I count 1...2...3. And just as everyone practiced the crowd hums AHHHHHHH! as science makes magic! 

Oh, and the BIG crowd pleaser of every show is when the aliens visit.

Then it's time for crowd brainstorming. Creative thinking. And FUN!

Of course, I share my amazing research adventures that are behind-my-book stories. Being inside NASA's space program, camping out with penguins in Antarctica, touring a chocolate factory, up-close-with an elephant named Baby Mike, a weta, a sloth, a boa constrictor named Rosie...and so much, much, much more.

I love the read aloud times with small groups. And there are those special times when I just visit classrooms. Then I share one of my books and listen to young writers reading their own stories. 

I also love time for small group visits with older students sharing my writing and book creating process. 

Of course, we take time for those memory moments...group photos, books to award-winning young authors, STEM team heading off to competition. 

It all comes down to........................................... 

IN-PERSON VISITS MEAN FOREVER AFTER

WORLD READ ALOUD DAY FEBRUARY FUN!

Start off this month's FUN by Visiting with me as I share COULD YOU EVER WADDLE WITH PENGUINS! (Scholastic)

Now, discover more fun on these dates.

February 16: OPERATION SANDBLAST The submarine USS Triton left New London, CT beginning what became the world's first underwater circumnavigation of the earth. It took 84 days and covered 41,500 miles. It also followed, generally, the route of the first ever circumnavigation of the globe by Ferdinand Magellan from 1519-1522. 

Challenge Ss to think about being inside a sub for 84 days. What would they have taken along to entertain themselves? And it would have had to fit in a small space! What would they have loved about this adventure? But what would they have missed most?

Also, challenge Ss to think about Magellan's crew being away from home for years! And no way to text or call!

February 17: NATIONAL RANDOM ACTS OF KINDNESS DAY. Think of some way to be nice to someone else.

Now, give each Ss another Ss's name to be their Secret Kindness Friend for a week or just a day. Have them leave their friend a note on a Kindness Message Board. Think what other little acts of kindness they might do?

February 20: is LOVE YOUR PET DAY. *I have to share one of my favorite love your pet books.

Challenge Ss to write a one paragraph story about their pet...Or their wished for pet.

February 22: POPCORN While this may not be the exact date, it's believe February, 1630 was when Native American Quadequina introduced early colonists to popped corn. You may be shocked to learn popcorn was the original puffed breakfast cereal. Popcorn was also worn by the early Native Americans. Have kids pop up some jewelry too. After threading dental floss through a needle have them poke the needle through the thickest part of the popped kernel. String necklaces or bracelets. After wearing, hang outdoors for bird snacks. 

February 25: READ ACROSS AMERICA begins today! It ends on March 2nd, Dr. Seuss's birthday. So be sure and read a Dr. Seuss book out loud today. *Here's my favorite.

And don't miss me reading to your Ss too.

I'm reading WHAT IF YOU COULD SNIFF LIKE A SHARK!? (Scholastic)

CELEBRATE PENGUIN AWARENESS DAY!

 I've written three books about penguins and each book has been about a different kind of penguin.

THE GREAT PENGUIN RESCUE
(Millbrook/Lerner, 2017) is about African penguins. 

A MOTHER'S JOURNEY (Charlesbridge, 2005) is about Emperor penguins.

PENGUINS: GROWING UP WILD (Currently Available on Amazon Kindle) is about Adelie penguins.

I love penguins because I had the wonderful opportunity twice to live with 160,000+ Adelies in Antarctica during the summer while they raised their chicks, watch Emperors from an icebreaker while they were riding on icebergs (off duty from wintertime egg hatching) and see even more kinds of penguins (Fairy Blue and Yellow-eyed) in New Zealand. 

So, here are some activities for you to enjoy getting to know the penguins in my books.

HOW PENGUINS STAY DRY
First, use the link to download 2 printable pictures of an African penguin--for each child.  

Next, supply children with paper cups of water and eyedroppers. Have them drip five drops of water on the uncolored African penguin. Then have them drip five drops on the colored African penguin. Ask, "What difference do you see?"

The children will observe the water soaks into the uncolored penguin and beads up on the colored on. African penguins, like all penguins, have a special gland that lets them spread an oily coat over their feathers. Like the wax, that lets their feather shed water. And penguin feathers are incredibly small (I know because I've held some in my hand). But the tiny feathers tuck tightly over each other, like roof shingles, to form a thick, watertight coat. In fact, penguins have more feathers than most birds--as many as 100 feather per square inch.

Emperor Dad On Duty

A MOTHER'S JOURNEY shares the less familiar story of what female emperors do while the dad's hunker down incubating their egg through Antarctica's freezing cold winter.  I know what winter in Antarctica is like. I experienced it firsthand at McMurdo Station.

Winds could be strong enough to lean into. Snow like tiny ice-glitter would fill the air. And temperatures averaged -50F to -70F (painfully cold to breathe) and dropped as low as -129F. It's an impressive cold. 

So the female emperor penguins get credit for traveling through this--in the dark--to reach open water and to feed, stay strong, and return just in time to feed their newly hatched chick. 

And the males get credit for staying the winter with the egg tucked into their brood patch (to share body warmth) and hold the egg on top of their feet to keep it off the cold ice and snow--even as they shift around with the huddle of other males. This activity will let kids get the idea.

Use any kind of baggie--even a self-sealing plastic bag. Put a ball inside to be the emperor penguin's egg.  First, have the children put their egg on top of their shoes (feet together) and practice waddling to move slowly without losing their egg. 

After a little practice, children are ready to be in a large penguin huddle with their egg on their feet. Tell them to pack as close together as they can. Then challenge them to waddle whenever you call "MOVE". And everyone at the outside of the huddle shifts one person to the inside. Repeat several times. 

It's fine for anyone who drops their eggs to return it to their feet. But point out Dad penguin must be quick in real life. Chilling puts the chick developing inside the egg at risk of not surviving to hatch.
