STEM Tuesday– CSI – Forensic Science and Anthropology- In the Classroom

By on November 12, 2019   /   CSI - Forensic Science and Anthropology, STEM Tuesday  

This month we’re investigating forensics and the science of crime scene investigation. Today, investigators rely on science to tell the story of a crime. High-tech cameras snap detailed crime scene pictures. Microscopes allow scientists to examine and identify the tiniest pieces of evidence. Understanding DNA and blood typing has created ways to tie a suspect to a crime scene without an eyewitness. Today, no one needs to catch a criminal in the act in order to solve a crime. The tools and techniques of science allow investigators to track down a criminal long after he or she has left the crime scene.

The books we’re highlighting this month show how science is used in crime scene investigations to find out what happened at a crime scene. They are a great starting point for different science activities and discussions in the classroom. Here are a few to try:

Blood, Bullets, and Bones: The Story of Forensic Science from Sherlock Holmes to DNA by Bridget Heos
Crime scene investigation is not new; early detectives discovered ways to test for poisons, and conducted autopsies to determine cause of death. Over the years, crime-solving tools have become more sophisticated as technology improves. This book examines evidence from prints to ballistics, blood spatter to DNA and more.
• Make a timeline of the evolution of forensics and crime scene investigation.
• Discuss how changes in forensic science have changed the way investigators solve crimes today. Have students research a famous unsolved crime from the past (such as the Zodiac killings, the Whitechapel murders, or the Marilyn Sheppard murder) and discuss how modern forensic methods might have made a difference in solving these crimes.

Fingerprints : Dead People Do Tell Tales by Chana Stiefel
Fingerprints are unique identifiers. Not even identical twins have the same fingerprints. This book explains the techniques scientists use to collect fingerprints and to identify criminals, and contains stories about how fingerprints helped solve real crimes.
• Have students examine their own fingerprints and find the marks and patterns that make them unique. Ask them to figure out how many of each type of fingerprint pattern they have among all 10 of their fingers. Have them compare their results with classmates.
• Have students try to lift fingerprints from a clear, hard surface. Have them sprinkle cocoa powder over the surface and gently brush. Next, have students place a piece of clear tape on the fingerprint and gently peel the tape off to lift the print. They can also experiment lifting fingerprints using different surfaces and powders.
• Have students attempt to match fingerprints taken from their classmates. Have them look for the patterns and characteristics that make each fingerprint unique.

Written in Bone: Buried Lives of Jamestown and Colonial Maryland by Sally M. Walker
Forensic scientists use their knowledge of human remains to help solve mysteries of remains found in colonial-era graves near Jamestown, Virginia. Using science, they help recreate the lives of a ship’s captain, an enslaved African girl, and more.
• Ask students to discuss what it means to be a forensic anthropologist. How does the job of a forensic anthropologist differ from that of a crime scene investigator?
• Often forensic anthropologists do not have an intact body or skeleton to examine. Instead, they build a picture of the victim with on a few bones as clues. Have students research how forensic anthropologists use the humerus bone (upper arm) and the tibia bone (inner leg) to predict the victim’s height. Have them test the correlation between height and bones by taking measurements from their classmates. Have them create a formula to predict the height from the length of a tibia or humerus bone. Then have students test their formula with measurements from another group of volunteers.
• What have forensic anthropologists added to our knowledge of the past? Have students choose and research a famous forensic anthropologist. Ask students to pair up and discuss how two different forensic anthropologists added to our knowledge of the past.

STEM Tuesday –Planes, Trains, Automobiles, and More! — Interview with Author Jennifer Swanson

By on October 22, 2019   /   STEM Tuesday, Transportation  

Welcome to STEM Tuesday: Author Interview & Book Giveaway, a repeating feature for the fourth Tuesday of every month. Go Science-Tech-Engineering-Math!

Today we’re interviewing Jennifer Swanson, author of Save the Crash Test Dummies.  Booklist gave it a starred review, calling it an “innovative blend of history, technology, and engineering…insightful fun. STEM at its best.”

Mary Kay Carson: Tell us a bit about your new book.

Watch the book trailer on YouTube!

Jennifer Swanson: The idea for this book came when I was writing another book — about electrical engineering. I did a section on the self-driving car and I was hooked. I wanted to ride in one, very badly. I sent email after email to Google asking if I could ride in one. Of course, I got no response. But that didn’t stop my interest. After all, I survived three teenage drivers, surely I could survive a self-driving car. 🙂  Anyway, I began to think, practically everyone rides in a car every day. I bet they don’t even think about how safe it is– OR how it got that way. Enter the crash-test dummies. We couldn’t live without them. Literally. Having them has helped engineers to save many, many lives. I knew then that I had to find a way to introduce the crash-test dummies to kids.

MKC: Any fun finds while researching the book?

Jennifer: I read a lot of car manuals and watched a LOT of videos of crashes. It was pretty cool. I do have to say my favorite moment, though, might have been when I came across the old crash-test dummy commercials that I remember watching as a kid. They are so fun! Here is a YouTube link to one of them if you want to check it out.

MKC: Do you choose to specifically write STEM books?

Jennifer: I have loved science my whole life. After all, I started a science club in my garage when I was 7 years old. My mom gave me a microscope and I used to collect leaves and flowers to look at under it. Gradually, my interests grew and I spent hours in the creek behind my house, making compounds with my multiple chemistry sets, and began dreaming of becoming a doctor one day. While that didn’t happen, I did get my B.S. in chemistry from the U.S. Naval Academy and my M.S. Ed in K-8 science education. Now I’m not just a science author, but also a middle school science teacher for Johns Hopkins Center for Talented Youth.

MKC: What approach or angle did you take to writing this book?

Jennifer Swanson is the award-winning author of over 35 nonfiction books for children. Her passion for science resonates in in all her books but especially, BRAIN GAMES (NGKids) and SUPER GEAR: Nanotechnology and Sports Team Up (Charlesbridge) which was named an NSTA Best STEM book of 2017. She has presented at multiple SCBWI conferences, National NSTA conferences, the Highlights Foundation, the World Science Festival and the Atlanta Science Festival. Visit her at jenniferswansonbooks.com.

Jennifer: When I write about technology and engineering I try to find a unique entry point, one that is FUN and unexpected. For this book, I really wanted to write a book about self-driving cars, but that seemed a bit, well, blah. I mean I find the engineering and technology that makes a self-driving car exciting and interesting, but not everyone does. So I asked myself how I could make this book interesting to people who maybe wouldn’t normally pick it up to read. The idea came to me after watching an old-time crash-test dummy commercial on TV. While on a walk with my husband, I made the comment that if we all went to self-driving cars, we wouldn’t need any more crash-test dummies. He responded by agreeing, saying you’d probably save alot of crash-test dummies. then. WHAM! That was it! Save the Crash-test Dummies, the history of car safety engineering. What a unique way to tell this story. Not only that, when I tell people the title, they usually smile (always a good sign). You see, finding a way to make engineering intriguing and complex topics easy to understand in my goal in my books.

Who did I write this book for? The kid who has TONS of questions about how the world works. That’s who I write all my books to. After all, I still am that 9-year-old kid that was full of curiosity and spent many hours devouring encyclopedias and nonfiction books at the library. Research ROCKS!

MKC: Could you give us a peek into your process?

Jennifer: My writing process is to find the hook for the book first. Usually that is in my title. For example, I wanted to write a book about nanotechnology and sports, so I titled my book SUPER GEAR: Nanotechnology and Sports Team Up. For my book comparing Astronauts and Aquanauts, I titled it (of course) Astronaut-Aquanaut: How Space Science and Sea Science Interact. When the hook to your book is in your title, people understand what the book is about right away. The second part of making a book is to find the structure. I ask myself, “what is the best way for this information to be presented?”. Then I read widely and look at a lot of mentor texts. Eventually I set on a structure. After I have those two things, I dive in into the research and write.

Win a FREE copy of Save the Crash Test Dummies!

Enter the giveaway by leaving a comment below. The randomly-chosen winner will be contacted via email and asked to provide a mailing address (within the U.S. only) to receive the book.

Good luck!

STEM Tuesday –Planes, Trains, Automobiles, and More! — Writing Crafts & Resources

Getting into Character

Planes, trains, automobiles, and more – this month’s look at transportation books might seem a bit impersonal, characterless, emotionless. When I looked closer, though, I found all kinds of characters. Let’s spend a few minutes examining how authors infuse character in these books about more technical topics.

Support Independent Bookstores - Visit IndieBound.orgBiography is an obvious approach, one taken in Elon Musk: And the Quest for a Fantastic Future. Following one individual’s life, author Ashley Vance shows us the development of his passion, the technical challenges he conquered, as well as the human challenges he dealt with. The results are an in-depth look at the skills needed to develop advanced transportation systems such as spaceships and electric cars.Support Independent Bookstores - Visit IndieBound.org

When tackling a topic such as the Titanic, which incorporate so much human tragedy, utilizing character is a natural fit. In Titanic: Voices from the Disaster, author Deborah Hopkinson interweaves individual’s stories to convey the magnitude of this event.

But even in a book with a much more technical focus, such as Who Built That? Bridges by Didier Cornille, space is given to including character. A single paragraph at the beginning of each chapter presents a brief expository bio before the chapter dives into the history and a step-by-step look at how each specific bridge was constructed.Support Independent Bookstores - Visit IndieBound.org

Support Independent Bookstores - Visit IndieBound.orgUse of character isn’t limited to actual human characters. Take a look at Save the Crash-test Dummies by Jennifer Swanson and you’ll see how inanimate dummy characters play a role in conveying the mechanical and historical content.

Why did each of these authors use character? I’m thinking deeper than the obvious answer: to draw the reader in. I’m comparing and contrasting how they presented these characters. The placement in the sequence of the text, the words used to describe the characters, the impact of character development, or lack of it. In analyzing this, I’m considering how I’ll use character in future writing to present topics that appeal to a wide variety of readers.

 

Try It Yourself:

  • Compare the first two pages of the first chapter of two books. Titanic and Elon Musk work well. Highlight every word or passage that characterizes the humans. Which techniques do these authors use? How similar or different are they? Consider why.
  • Now focus on a single book, Save the Crash-test Dummies, is ideal for this exercise. Scan the book for places where the nonhuman characters are characterized. Where is that in the sequence of the book? Can you find examples of characterization in places other than the main text?
  • Think about characterization in expository versus narrative text. Look for examples of each in this collection of books. Find an example of expository characterization (as in Who Built That? Bridges) and rewrite that is narrative. Yes you probably have to make it up; that’s okay for an exercise. Find an example of narrative characterization and rewrite that as expository. Which was harder? Why? How would making that change to the text impact the larger piece of writing?


Heather L. Montgomery writes books for kids are wild about animals; she’s learned to bring characterization into her works. Her recent Something Rotten: A Fresh Look at Roadkill follows an inquisitive narrator who visits scientists who use roadkill bodies to make discoveries. Her Little Monsters of the Ocean: Metamorphosis under the Waves characterizes juvenile marine creatures to tell the story of how they each grow up.
