Beauty and the Beak

Beauty and the Beak: how science, technology, and a 3-D printed beak rescued a Bald Eagle.
by Deborah Lee Rose and Jane Veltkamp
48 pages; ages 5-12
Persnickety Press, 2017

themes: engineering, animal rescue, nonfiction

In a huge nest of twigs, high above an icy cold Alaskan river, a Bald Eagle chick cracked open her egg.

At first she's covered in down. But soon her wings become longer and stronger. Bit by bit her feathers grow in. She's a teen, taking test flights, and then off on her own. She hunts, eats, and soon is ready to fly back to the land where she was born. But one day she is shot in the face. A bullet shatters her beak, tears her eye, and leaves her bleeding.

"Beauty" is rescued and taken to a wildlife center where she can heal. But she can't eat or drink because her beak hasn't grown back. Then Janie, a raptor rehabilitator, takes Beauty to a raptor center in Idaho. She works with an engineer to try something crazy: create a prosthetic beak for the eagle - and make it with a 3-D printer! But would it work? It did, and Beauty learned to eat and drink again on her own.

What I like about this book: This is a true story of how engineering and technology come to the rescue! That would be enough, but there are 16 pages of back matter packed with details about Beauty's beak and other prosthetic devices, as well as tons of facts about Bald Eagles.

I also like that this book comes out in the tenth anniversary year of the Bald Eagle being taken off the Endangered Species List. Even though they are no longer "endangered", Bald Eagles still face many risks - especially from human activity. People shoot them, or the eagles collide with cars, trains, or power lines.

Beyond the Book:
Listen to sounds made by Bald Eagles at Cornell Lab of Ornithology's website. You can also learn how to identify Bald Eagles.

Watch Bald Eagles via "eagle cam". Here's one in Washington DC. Season is over, now, but you can review the summer highlights.

Check out this post on "Wild Engineering."  And then head over to see this video about how the engineers created Beauty's new beak.

Then try your hand at engineering a prosthetic tail for fish! Download this pdf for some science and engineering fun.

Wednesday Explorers Club - unseasonal observations

Walking through town the other day I saw some trees blooming. Even my forsythia is blooming again. It's October! Granted, we've had a lo-o-ong summer, but the red on trees should be leaves turning color.

Which brings me to phenology: the study of cyclic and seasonal natural phenomena. According to the US National Phenology Network, "Changes in phenological events like flowering and animal migration are among the most sensitive biological responses to climate change. Across the world, many spring events are occurring earlier—and fall events are happening later—than they did in the past." 

You can help scientists by keeping track of flower blooms, bird migrations, insects emerging, and other natural phenomena by becoming a citizen scientist through Project BudBurst. All you need is a journal, a pencil, and insatiable curiosity. Despite its name, you don't have to wait until spring to make observations. You can start now. Have fun!

Super Women ~ Six scientists who changed the world

Super Women, Six scientists who changed the world
by Laurie Lawlor
64 pages; ages 8-12
Holiday House, 2017

"Imagine being a highly trained astronomer who's forbidden to look through a state-of-the-art telescope," writes Laurie Lawler. Or that you're an accomplished underwater cartographer not allowed on a research vessel, or a chemist not allowed to work in a research lab.

Not because you don't have the skills - but only because you're a woman. We're not talking about women in science hundreds of years ago, but within our lifetime. Absurd, right?

And yet, Lawlor has compiled half a dozen stories of real scientists who had to fight against gender discrimination to do their research. Her tales include:
  • Eugenie  Clark, known as the "shark lady" - an oceanographer who dives into the sea to study sharks and other creatures living in the deep. Her research helped people understand that sharks can learn. Scientist, explorer, Clark authored more than 175 scholarly and popular science articles and been a champion of ocean conservation.
  • Gertrude Elion shares the 1988 Nobel Prize in Physiology & Medicine with George Hitchings and Sir James Black. Her research contributes to drug treatment for cancers. But when she graduated in 1937 with high honors in chemistry, she was turned away from research labs because hiring a woman would be "too distracting".
  • Katherine Coleman Johnson served as a human "computer", one of a team of mathematicians who helped send Alan B. Shepard, Jr. into orbit around Earth. As an African American woman and mathematician, she faced many obstacles working in the brand new space agency, whose technical staff was mostly white and male. In 2015, President Obama awarded her the Presidential Medal of Freedom.
  • Marie Tharp mapped underwater mountains, valleys, ridges, and plains. She was one of the first scientists to notice evidence for plate tectonics. Other researchers discounted her thoughts as "wacky ideas" and "girl talk", but eventually she convinced them. She worked with another researcher to create the world ocean floor map.
  • Florence Hawley Ellis wanted to be an archeologist, but men joked that she'd never find workers willing to follow her into the field. In addition to digging up artifacts, she collected information from Pueblo and Navajo elders about customs, stories, social organizations and more. She also noticed historical evidence of droughts and ongoing perils of climate change in the Southwest. 
  • Eleanor Margaret Burbidge is an astronomer who hunts deep-space objects. She viewed the first image of a quasar that was billions of light years from Earth. But in the early years of her career, institutes denied women access to telescopes because the living quarters were meant to be places where male astronomers wouldn't be bothered by wives or family. She finagled a way to live off campus and use the telescope and has contributed greatly to the field of astronomy.
The book is filled with photos, and complemented with a glossary where you can quickly look up "quasar".

Wednesday Explorers Club ~ A Seedy Walk

Head out on a seedy field trip. Pull a large pair of old socks over your shoes and up your legs. Then head outside and walk through a weedy area - maybe next to a country road, or at the far end of a park, a hay field or even your garden.

You might be surprised by how many seeds "hitch" a ride.

When you get home, pull the seeds off your socks and take a close look at them - a magnifying lens will help. Can you figure out what plants they come from?

Sort them by what they look like. If you have some potting soil, fill up some paper cups and plant the seeds. Can you grow them into new plants?
