In case you haven't "heard," National Geographic Channel has a seven-part series coming in November called Great Migrations (links are no longer available). Affiliated with the television event are a number of educational opportunities you might want to investigate.

Accompanying the series is a children's book, Great Migrations:  Whales, Wildebeests, Butterflies, Elephants, and Other Amazing Animals on the Move by Elizabeth Carney.

Great Migrations contains the dramatic, stunning photographs you have come to expect from National Geographic. Each animal is given a four page spread. The first two pages are amazing scenes in vibrant color. The second two pages are facts about the migrations those animals take that includes a map of the region where the animals occur (geography lesson).

I do have one caveat. The font on these informational pages jumps around drastically in color and size, even within a paragraph. While this is eye-catching from a design point of view, on the other hand it is a real challenge for beginning and struggling readers to follow.

If you are going to watch the series and want to have a reference on hand to emphasize points or delve a bit further into details, then this book could be a useful tool. It will be sure to get children interested in learning more.

There is also an adult book, Great Migrations by K. M. Kostyal, which I haven't seen yet.

This trailer to give you an idea what the series is like (may not be suitable for sensitive children):

Isn't that stunning?

Note:  I'm sure there will be some scenes of predators capturing prey in the actual show, so it may not be suitable for young or highly-sensitive children.

Great Migrations by K. M. Kostyal


Our Weekend Science Fun is inspired by the book Inside Hurricanes by Mary Kay Carson. The book is reviewed is at Wrapped in Foil.

We were excited by the story of a unique dome-shaped beach home that survived when Hurricane Ivan hit Pensacola Beach, Florida in 2004. The owner had designed it so that winds blew around it and that storm surges could pass under. It turned out that the home with an interesting design passed the hurricane test. We decided to try out some of these ideas on our own.

Activity:  Does building shape influence level of damage by hurricane-force winds?


  • computer paper
  • access to a computer and printer
  • tape or glue
  • scissors
  • hairdryer, to supply "hurricane winds"

First we will make structures of three different shapes:  rectangular, circular and a pyramid. (See photograph below.)


Go to and print out the Great Pyramid pattern. Cut it out and assemble. Tape or glue tab.

Paper House - Rectangular

Start with a piece of computer paper.

(If you have difficulty seeing these instructions, let me know.)


Cut another sheet of computer paper roughly in half lengthwise. Lay both layers on top of one another (we're trying to keep the weight of each house roughly the same). Bring the ends together to form a cylinder and tape or glue to hold.

Predict which of these shapes can withstand wind the best.

Find a flat surface that is near an electrical outlet, so you can plug in the hairdryer. Now place a penny or other marker on the flat surface. Rest one of the buildings on it. Plug in the hairdryer. If possible record how fast and/or how far the building travels when you blow the hairdryer on it. Try to stand a consistent distance from the building with the hairdryer. Repeat with the other buildings, making sure to place them on the same mark each time.

If you aren't seeing any differences between the buildings, try lowering the setting on the hairdryer and/or standing farther away.

Extensions:  Try modifying the shape of the building, changing the weight of the paper you use to construct the buildings, or changing the speed of the hairdryer.

Isn't it fun when reading a book makes you want to try out something yourself?

Today let's use the recently released book  Astro: The Steller Sea Lion
by Jeanne Walker Harvey and Illustrated by Shennen Bersani to explore an interesting sea mammal. Astro-the-steller-sea-lion

Astro, who was orphaned at birth and raised by humans, has become an ambassador for his species. If we could interview Astro, here's what he might have to say:


Interviewer (from now on in bold): Can you start by you telling our audience what kind of animal you are?

Astro (plain text):  I am a Steller sea lion.

Does that mean you are stellar, like a star?

No, my species is named for Mr. George Wilhelm Steller, a famous explorer and naturalist who discovered us in Alaska in 1741.

I have been to California and seen California sea lions, are you one of those?

No, my species tends to be larger and lighter colored. We are also much less common. In fact, those of us that live along the eastern Pacific coasts are threatened, and those along the western Pacific coasts are endangered.

What does that mean?

It means that if people aren't careful we could go the way of the Steller's sea cow.

What is a Steller's sea cow? I've never heard of it.

The Steller's sea cow was another sea mammal named by Mr. Steller in 1741. They looked sort of like the manatees now found in Florida. They were gentle plant-eating giants. Because the sea cows were good to eat, they were extinct only 27 years after Mr. Steller found them.

Yikes, that is sad. Hope that doesn't happen to your species.

With luck, this new book will help inform many people about us.

Tell me about "your" new book.

Jeanne Walker Harvey has written the story of my life up to now. She explains how I was orphaned at birth on an island off the coast of California. A scientist found me and took me to the Marine Mammal  Center. The humans took really good care of me. In fact, whenever they tried to send me back to the wild, I just kept coming back to them. Finally, they found a home for me at the Mystic Aquarium in Connecticut, where I live now.

And you know the best part?

What's that?

Jeanne is donating a percentage of the royalties from the book to both the Marine Mammal Center and to Mystic Aquarium.  Think of all the sea creatures like me that will help.

Anything else about the book?

What I want to know is how Shennen Bersani did those fantastic illustrations. She always shows my best side.

Hey, I thought I was asking the questions.

Didn't you write to her?

Yes, I asked her how she made the illustrations and here's what she said:

"I've been using colored pencils for a long time, I've even taught classes and workshops on their use... so most of what you see in Astro is colored pencil on Arches watercolor paper, with a splash of acrylic paint."

How are the colored pencils so rich? They look like photographs, only much more luminescent.

"Layers!  Layer upon layer of pencil is used with a 'toothy' paper.  Layers are the best way to explain it.  Does that explanation help?  I use a graphite pencil, nothing fancy there, to draw out the image on the Arches.  (You can see some of my actual sketches turned into coloring pages on the Sylvan Dell website under Astro Teaching Activities.)  Then I color them in with the colored pencils, and highlight some areas with acrylic paint."

Many of the people look like my real friends. How did she do that?

About the models, Shennen Bersani said:

"I traveled cross-country to step in Astro's, umm flippers.  I met with some of the actual people who worked with Astro - and included likenesses of them when possible. I also had fun including my family members, friends, neighbors, and myself."

Isn't that fun? We should tell the children in the audience to check out Shennen Bersani's picture in the back of the book and on her website, and then look for her in the illustrations. It will be our little secret.

Would you tell her that I appreciate all her hard work?

I think she knows. So, Astro, do you think there will be a sequel to your book?

Actually, I was thinking I'd make a great movie star!


If you are interested in using this book as a teaching tool, visit Sylvan Dell Publishing's Astro page for Teaching Activities in the form of a .pdf booklet.

Check out how you can use zoo or aquarium observations as a science project at Dragonfly TV.

The Sea World Education Department has downloadable .pdf teacher's guides on Seals, Sea Lions, and Walruses (scroll down page for links), as well as other ocean-related topics.

Have you ever seen the California sea lions at Pier 39 in San Francisco, California?


The California Academy of Sciences has a video that explains why their numbers have recently decreased and also why tagging certain individuals gives us useful information.

And here's a video of Astro in action. I think he's right, he would make a great movie star.
