What a day it was! Ms. Mitchell was right; I was exhausted at the end, but all of it was worth it.

Humble ISD Elementary school second, third and fourth grade students dove with me into the deepest oceans to uncover the secrets of deep diving mammals. After, we travelled to African deserts tagging along with scientists who worked with live-size toy lions to reveal what the lion’s mane is for.

The students were an amazing audience; attentive, curious and asked so many questions that I barely had the time to answer them all.

Thank you all for a wonderful experience!

“Teachers and students learned a lot and are excited to read your books; we already have a check-out waiting list!” Ms. Mitchell said later on an email.

What else can I ask for? Happy reading!


On January 5th, Archimedes Notebook posted a wonderful review of "The Secret of the Scuba Diving Spider," unfortunately, life got in the way and I did not see it until today.

I am xcited to share good news for Animal Secrets Revealed! series! School Library Journal Series Made Easy gave it a wonderful review.

Click on the image to the left to read the review and recommendation, find where to download the free teacher's guides, and take advantage of a special offer for school and public libraries by Enslow Publishers.

Teachers and librarians, are you looking to bring the excitement of science and nature to your school?

Animal Secrets Revealed! can trigger your students' innate curiosity and engage them in an educational exploration of the natural world.

Some scientists let their curiosity make them do truly weird experiments. Meet Ken Catania. He studies strange-looking creatures, such as the star-nosed mole and its unusual way to smell underwater. More recently, Catania has been focusing on electric eels, and their ‘shocking’ abilities.

He discovered that eels can control how much electricity they put out. They use low voltage pulses to sense for prey, and they can turn up the power to make prey (think of fish) twitch or go numb. That was fascinating, but then Catania came across an 1800s illustration and an odd South American story from famous explorer Alexander von Humboldt. Humboldt wrote of eels attacking a group of horses that had stepped into a pool where the eels lived.

“The aggressive behavior of the eels, taking the offensive against the horses, seems the most fantastic and questionable part of the story,” he said.

Just when scientists thought they knew all there was to know about electric eels, here comes an old tale that makes them wonder. Can eels really jump out of the water? Catania had to solve the mystery and so he did using props shaped like alligator heads and human arms, and electric connections to see with his own eyes whether eels in his lab could jump as Humboldt’s allegedly did.

The Shocking Secret of the Electric Eel book also includes four more secrets: how parrot fish don’t let the sea bugs bite, the jumping spider’s amazing ‘hairy’ hearing, the mystery of European eels and their heads (these are much smaller that the electric eel and won’t shock you), and the secret of the underwater night hummers.

May I entice you with more animal secrets? I invite you to visit my website to explore the other titles of this series.

I am resuming my weekly blogging about nonfiction books that have caught my attention. This definitely qualifies with 5 out of 5 stars. Black holes are still full of mystery, however the author and the illustrator succeeded showing us that hard science does not have to be hard to understand. It's fun, it's accurate, entertaining and definitely informative! Check it out by clicking on the image.

"Toward the tail it appeared serrated,...with something moving flail-like at the extreme end. The movements were like those of a crocodile. Around the head appeared a sort of mane, which drifted around the body like kelp."

"A sea otter is quite large; a male can be as big as a German shepherd dog. They are good parents too. Sometimes sea otter moms will wrap their pup in kelp (a large, brown seaweed) to keep it in one place while she dives for food. River otters are half or a third of the size of a sea otter, but they are equally fascinating...." Intrigued? Click on the otter on the left to go to Ana's Nonfiction Blog.

I have joined Random Acts of Publicity, created by Darcy Pattison on Facebook. This event is to BLLuRT (Blog, Like, Link, Review, and/or Talk) about a friend's book or another favorite book to spread the word about it. I think Marianne Dyson's award-winning "Space Station Science" is a must read for kids (and adults) and a must have for libraries because it is about one of the most amazing and important human achievements. Currently, the SS is in our minds, as well as the astronauts in it and their families, because there have been problems bringing them supplies. Check the news links in the blog and follow this story by cliking on the astronaut on the left. Come and join me!
