STEM Tuesday– Fossils– Book List

Ancient Stories Cast in Stone

Every fossil tells a tale. It could be a story about an adventurous life in the ocean, before becoming buried beneath layers of sediment. Or it could just raise lots of questions, starting with: how did that get here?

Mary Anning and Paleontology for Kids: Her Life and Discoveries, with 21 Activities by Stephanie Bearce

Readers get to know Mary Anning as a child and, later, as she discovers her first skeleton. Mary did more than dig up bones, though. She cleaned them, figured out how to put them together in a complete skeleton, and drew detailed scientific illustrations about her finds. Scattered throughout the book are sidebars that dive into details about aspects of life in the 1800s as well as the hands-on activities.

Gutsy Girls Go for Science: Paleontologists: With Stem Projects for Kids by Karen Bush Gibson, illustrated by Hui Li

Paleontologists are the scientists who study fossils, from ferns to trilobites, dinosaurs to ancient humans. In this book, we meet five women in paleontology, beginning with twelve-year-old Mary Anning who, in 1811, found a dinosaur in the cliffs near her home. We meet Mignon Talbot who studied crinoids and is the first American woman to discover and name a dinosaur. There’s a field kit checklist, lots of hands on “field assignments” and plenty of text-boxes, along with short bios of other paleontologists not featured.

The Monster’s Bones : The Discovery of T. Rex and How It Shook Our World (young reader’s edition) by David K Randall

The life of a paleontologist is filled with grit and heat, stone and hammers, and the occasional train robbery. After a nod to 19th century paleontologists, this book takes us into the fossil beds of Wyoming and Montana with Barnum Brown and the American Museum of Natural History. Wealthy capitalists fund fossil-hunters hoping to feature the largest, fiercest monsters in their museum halls.

Tales of the Prehistoric World: Adventures from the Land of the Dinosaurs by Kallie Moore, illustrated by Becky Thorns

How do stromatolites in Australia connect to Mars? Starting with the answer provided by these oldest known fossils (3.5 billion years old), we are led on an engaging journey forward through time. Detailed discussions of the life found in each period are sandwiched between captivating accounts of the intrigues, adventures, and conflicts of scientists, kids, farmers, and miners who discovered some unique and surprising fossils.

Kid Paleontologist: Explore the Remarkable Dinosaurs, Fossils Finds, and Discoveries of the Prehistoric Era by Thomas Nelson, illustrated by Julius Csotonyi

A great discussion of the field of paleontology is followed by an introduction to “10 Famous Paleontologists,” a list of “10 Famous Fossil Sites” in the world, and an engaging dinosaur classification chart. Stunning “true-life” illustrations and a conversational narrative first explore ten dinosaurs which defy classification (including one that was a burrower) and then examine many other familiar and lesser-known dinosaurs from the perspective of what their fossils, imprints, CT scans, and stomach contents have taught paleontologists about each species and what is still unknown. Highlighting where initial guesses or information has been corrected by subsequent fossil discoveries. A great book to inspire future fossil hunters.

Rhinos in Nebraska : the Amazing Discovery of the Ashfall Fossil Beds by Alison Pearce Stevens

Twelve million years ago rhinos lived in Nebraska – alongside horses and other grassland creatures. It was peaceful until… a supervolcano exploded, spewing tons of ash into the air and burying the rhinos. This book takes readers to the Ashfall Fossil Beds where they’ll look over the shoulders of scientists digging up the bones of more than 50 rhinos and uncover a few mysteries along the way.

The Illustrated Guide to Fossils & Fossil Collecting by Steve Kelly

Amazing photographs of fossils combine with reconstruction illustrations to give the reader a sense of what each animal or plant might have looked like. Following a discussion of fossils, geologic timeline, and reconstruction challenges, the detailed directory of 375 plant and animals fossils includes an additional fact file, and the relationship of the fossil to its current relatives and their role in the environment.

Fossils for Kids: An Introduction to Paleontology by Dan R Lynch

This photo-illustrated book dives into rocks, minerals, and fossilization. A vertical color-coded geologic timeline accompanies a lively, question and answer discussion of seventeen kinds of animal fossils, six plant and amber fossils, and an examination of microfossils, trace fossils, and pseudofossils. Advice on safely collecting fossils and avoiding fakes is followed by a list of fossil sites around the U.S.

Fossils for Kids: a Junior Scientist’s Guide to Dinosaur Bones, Ancient Animals, and Prehistoric Life on Earth by Ashley Hall

Written by a paleontologist with the goal of exciting future scientists, the book employs a conversational and lightly tongue-in-cheek narrative and great illustrations to explore fossil formation, classification, and identification and then dives into an examination of the fossils, stats, and discovery locations of dinosaurs, vertebrates, invertebrates, and plants. Wonderful side bars expand upon the science, explore famous scientists, and offer a “make your own fossil” activity.

My Book of Fossils: A Fact-filled Guide to Prehistoric Life by Dr. Dean Lomax

This photo-illustrated, browsable hi-low book explores the creation and collection, excavation and discoveries of fossils. Interspersed with fascinating features and scientific discoveries about bacteria, plants, and animals, are gemstone fossils, famous paleontologists, reconstructing the past, and an awesome visual glossary/index.

STEM Tuesday– Cryptography (Math)/Spy Science– Writing Tips & Resources

 

noun: cryptology

  1. the study of codes, or the art of writing and solving them.

As an advocate for STE(A)M, I want to connect cryptology to the arts. It may seem an unlikely connection, but there are many examples of hidden messages in literature, music, and visual art. I give examples below and include an art activity and a link to an article that gives examples of contemporary hidden messages.

Literature

For older readers, there is the classic THE DAVINCI CODE by Dan Brown. Many of you may have wondered (I sure did) how much was real and how much made up. But this post isn’t about the novel but using it as an example of code in literature. Middle grade writers like Blue Balliett and Ellen Raskin incorporate puzzles to solve and provide clues for an alert reader. I enjoy stories about secret messages and clues and it adds another level of mental activity to the reading.

Music

Music has provided opportunities as well for secret meanings. I’ve included classical examples here. And one of my favorite musical examples is in the Alfred Hitchcock film “The Lady Vanishes.” Miss Froy disappears but not before she entrusts Iris and Gilbert with a musical phrase that passes a secret message to the Foreign Office.

From the online article Musical Cryptography: Hiding Messages in the Music! (link below) from PuzzleNation Blog.

 This sort of musical wordplay appears in compositions by Ravel, Debussy, and Shostakovich among others. Johann Sebastian Bach did this often enough that the succession of notes B-A-C-H is now called a Bach motif.

The composer Dmitri Shostakovich lived under a very repressive regime in Russia. He included passages in his compositions that “critiqued” the government. However the members of the government didn’t know enough about music to see that. This was dangerous because penalties for speaking against the government were severe.

Visual art/graphic design

For an activity this month, I am looking at Secret Messages in a way we see every day. The opportunities to be a spy are few these days, but knowing how to spot messages coming to you is a good skill. According to John Hopkins Center for Talented Youth, Cryptology is the study of the codes and ciphers used to create secret writing. We usually think of spies and stories, but there is “secret writing” all over.

For instance, in the article 36 Hidden Messages in Company Logos You See All the Time, by Kelly Kuehn (link below) you can see how people are influenced without even realizing they are being influenced. Check out the article for other examples.

You may have thought the dot over the “i” was used to give the logo a pop of color, but it’s actually part of a hidden—and creative—message. The red dot is actually a bowl of salsa. The two T’s are people, and the yellow triangle in between them is a chip. It’s supposed to represent people coming together to share a tasty snack of chips and salsa.

Once you know that this is common, you can find examples of hidden messages all over.

When I was teaching graphic design in at university, I had the students make 50 (yes, 50) small logo sketches, known as thumbnails, with their initials. We used tracing paper and pencil and it was about ideas, not perfection. Then we could discuss the merits of some of the individual ideas and use them to move on to a more polished design. You can, of course, make fewer sketches – how many you need to get the idea you like.

There are two aspects to consider. One is the visual part. Is it attractive? Colorful? Compact? Attention getting?

The second aspect is the underlying meaning. Does it respond to the personality of the designer? And – does it say more than an initial quick glance would reveal? Here is where the hidden meaning comes in. This requires higher level thinking to manipulate the space to include a secret message.

It helps to have a plan.

  1. What is the overall spirit of the logo? Some possible answers are serious, playful, sporty, mysterious. Write it down to remind yourself.
  2. What is the secret message? Your answer to #1 might be sporty so somewhere there could be the shape of say, a soccer ball or a running shoe. Can you incorporate it into the design so that it isn’t immediately apparent, but is easily recognizable? There are many books on logo design, both how-to and the best-of.
  3. Try to make the final drawing clean and in black and white.

Yes, a challenge. Sometimes it helps to work with a partner or a team, the way a professional design studio would work.

After settling on an idea, then make a Very Clean drawing.  The drawings can be scanned (at 300dpi) as jpgs or pngs, for use on such documents as school assignments. For younger grades, a rubber stamp or stickers are fun for embellishments.

Have fun with your secret message logo!

STEM Tuesday– Cryptography (Math)/Spy Science– In the Classroom

In my former career, I worked with communications and communication security (which included cryptography). It is a topic that will always be near and dear to my heart. This month, I read the following books:

 

How to Be an International Spy book

How to Be an International Spy by Andy Briggs

This book covers lots of different topics associated with being a spy. The science around it all ranges from psychology to quantum physics. It includes lots of practice activities to help you fully engage in the topic.

 

Top Secret Science Book

Top Secret Science: Projects You’re Not Supposed to Know About by Jennifer Swanson

If you’re looking more for the history of secret projects, this is the book for you. It looks at a variety of programs that were run in secret.

 

Can You Crack the Code book

Can You Crack the Code? by Ella Schwartz and Lily Williams

If your goal is to learn how to create and crack secret codes, you might want to check out this book. It does a great job of covering the major cryptography methods. There are lots of secret codes to practice with, too.

 

 

Rather than making up activities to go along with these books, I want to share some of the fabulous resources that are already out there that would pair well with this month’s theme.

Check out “The Farm”

The CIA may be a secretive organization, but they’ve got an online presence. There are stories, games, activities, and other things for young readers to explore on their CIA Spy Kids site: https://www.cia.gov/spy-kids/games

They’ve also developed lesson plans for teachers: https://www.cia.gov/spy-kids/parents-teachers

Delve into Cybersecurity

Cybersecurity ensures that electronic devices are protected from criminal or unauthorized use. There are lots of career opportunities in cybersecurity, so it’s a great topic to learn more about.

The University of Texas at San Antonio’s Center for Infrastructure Assurance & Security (a.k.a. UTSA CIAS) has lots of resources for teachers and students on their website. Their activities cover grades K through 12. Here’s their main page: https://cias.utsa.edu/k-12

Their Cyber Games are found here: https://cias.utsa.edu/k-12/cybersecurity-games

Microsoft and Minecraft teamed together to provide resources for teaching cybersecurity, too. Check that out here: https://www.microsoft.com/en-us/education/blog/2023/10/elevate-cybersecurity-expertise-with-microsoft-and-minecraft-education

Learn About Public Key Encryption

Public Key Encryption is used to secure many different types of transactions on the internet, from email to online store payments. This video from PBS NOVA labs does a great job of explaining at a high level how public key encryption works: https://youtu.be/5xI4IJbHDiM?si=mM6cZJdTDUjeqVOs

NOVA Labs also has a cybersecurity game online: https://www.pbs.org/wgbh/nova/labs/lab/cyber – there is an educator guide to go along with it.

Cryptography in History

Pretty much all the books this month talk about the long history of secret-keeping (and cryptography to help with that). Here are some web sites that explore cryptography in history.

“The Secret Code of Lewis and Clark” activity: https://lewisandclarktrail.com/legacy/secretcode.htm

“Cryptology in the American Revolution” videos from NSA’s National Cryptologic Museum:
