STEM Tuesday — Geology — Interview with Author Jennifer Swanson

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 recently released OUTDOOR SCHOOL: Rock, Fossil, and Shell Hunting. In a shining starred review, Kirkus says it’s a “stellar guide that engages readers with rocks, minerals, fossils, and shells.”

Mary Kay Carson: How did you come to write Rock, Fossil, and Shell Hunting?

Jennifer Swanson: I wrote this book because the publisher reached out to me to ask me to write it. That happens sometimes when you are a STEM nonfiction author. The publisher comes up with an amazing idea and then they look for an author to write the book. Why did they ask me? Well, probably because of my background as an author of STEM books for kids, but also because I am a huge fan of science and the outdoors. I grew up with a creek in my backyard and practically spent my entire childhood running around outside along the creek, climbing trees, tromping in the forest, and much more. Writing this book was awesome! because it helped me to relive my childhood in a lot of ways.

There is a whole Outdoor School series! Check out the other two amazing books: Outdoor School: Hiking and Camping by Jennifer Pharr Davis and Haley Blevins, and as you know, Outdoor School: Animal Watching by Mary Kay Carson. If you have kids who love the outdoors, these three books are a must. Kids of all ages will find themselves armed with tons of maps, tips, and tricks to explore the outdoors like never before. If you want to continue the fun, draw images of what you see, organize the collections that you gather, and get to the library to look for more fun books about these topics.

MKC: The book is billed as “The Definitive Guide” and is 440 pages. What was researching it like?

Jennifer: As I mentioned before, I spent  my childhood outside, so I guess you could say that I’ve been researching this book my whole life. But to be more specific, with a book this long, there is a lot of research. I got very familiar with adult field guides of rocks, fossils, and shells (those are very big books, if I do say so myself). And then I wrote the experiments and actually did them. I mean you have to make sure they will work, right? The writing part took a lot of time, as did the editing. We had to go over each illustration to make sure it accurately represented every rock, fossil, and shell in it. Plus, I added in some safety notes throughout as well as suggestions for where to go to find all of these amazing objects to add to your collection.

MKC: Were you a rock or shell collector as a kid? Are you still?

Jennifer: Yes! I collected them all, or tried to anyway. I had a ton of rocks as a kid and shells, too. I never did find a dinosaur fossil, though. Isn’t that the goal of every kid? But I did get close (sort of). I found a cow skull when I was eight. It was the prize centerpiece of the science club I had in my garage. As an adult, I don’t collect as many rocks, fossils, or shells, as I realize that they are important parts of the ecosystem. So while I look for them, I usually leave them in place in the wild.

MKC: To whom did you imagine yourself writing to while drafting this book?

Jennifer Swanson is the award-winning author of over 35 children’s books, including Brain Games, Super Gear, Astronaut-Aquanaut, and Save the Crash-test Dummies. A self-professed science geek, she started a science club in her garage when she was 7 years old. When not researching cool STEM stuff or writing about it, you can find her walking along the beach with her husband and her dogs, looking for shells.

Jennifer:  Like all my books, I write my books for kids who love science, engineering and the outdoors. For me, writing STEM/STEAM books is about having a conversation with a young reader. It’s about getting them excited about the topic so that they get curious, ask questions, and want to explore more on their own. I love including fun facts so that my readers say, “Wow! I didn’t know that.”  The target audience is kids ages 10-14 years, but really it’s a great book for kids of all ages (yes, that means adults, too). If you love the outdoors or just want to get more familiar with it, this book is awesome for just that!

MKC: Could you give us a peek into your process by sharing where you are right now on a current project?

Jennifer: Right now I’m working on my new book, Saving the Amazon which features a team of scientists from the Field Museum in Chicago who work to help countries decide if a certain part of the land in the Amazon should be conserved for national parks or protected lands. The team goes into an area and  inventories everything! from the animals that creep on the land to the birds that fly in the trees to the fish in the waterways, plus the plants and people that live there, too. It’s a fascinating process and one I’m honored to be able to tell kids about. My process is to interview each scientist/expert on the team, look through photos, papers, and other resources they have and then to visit the Field Museum for onsite research. For me, this is one of the most exciting parts about writing the book– doing the research and interacting with the scientists. The book will be published by Charlesbridge Publishing in 2023. I’m so excited about it!


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– Geology — Writing Tips & Resources

STEM Tuesday

Layering It On

This month’s #STEM Tuesday book list focuses on geology, which Merriam-Webster defines as “a science that deals with the history of the earth and its life especially as recorded in rocks.”

In reading this month’s books, I was struck by all the images of rock layers, including this one from Jen Swanson’s OUTDOOR SCHOOL: Rock, Fossil, and Gem Hunting.

An image of rock layers

I learned that every layer gives us a piece of  information about the Earth’s history. Some layers have fossils revealing how long ago the layer formed. Others contain rocks and sediment that tell us if water was involved in deposition. Taken together, these layers help us see the big picture about Earth’s history.

Text Features — A Book’s Layers

Books are layered just like the Earth. Text features are the layers that help readers understand the book’s content. These text features include elements like captions, graphics, and labels. Let’s take a look at the graphic below from from DIRTMEISTER’S NITTY GRITTY PLANET EARTH by Steve Tomecek to learn more about text features.

  • Table of contents – Normally found at the beginning of the book, a table of contents is like a map. It tells you the topics the book will cover and how to find them by listing the page numbers. 
  • Subheadings – Often nonfiction chapters are carved up into smaller chunks, each with its own subheading. These subheadings tell you exactly what the next section of text is about.
  • Illustrations/photographs – You know that saying, “A picture’s worth a thousand words?” Just think how much easier it is to show you the tectonic plates in the image above, rather than trying to describe what them using text. Illustrations and photographs convey information that may be more difficult to describe in the text.
  • Captions – These are most often found under an image. They normally are a sentence or two long.
  • Labels – These are snippets of information placed on an image itself. Labels call out parts or features of an image, like the labels I’ve used in this graphic to call out the various text features.
  • Sidebars – Sidebars have additional information related to the main part of the text.
  • Graphics like graphs and charts– These organize information visually. They are especially helpful for showing processes or giving meaning to numbers.
  • Maps- Show you important locations mentioned in the text.
  • Special print (typography) – Sometimes print is bolded, like glossary words the author wants you to know. Italics and underlines provide emphasis.
  • Index – Found at the end of a book, an index is alphabetized, helping you quickly look up ideas, concepts, and names and find which pages will tell you more.
  • Glossary – Gives definitions for bolded words in the text. Think of it like a little dictionary in the book.

Teaching About Text Features

Have students look at some of the books on this month’s Geology list, then:

  • Consider creating a bingo card of text features for students to cross off as they find them.
  • Ask: Did students find any other text features not mentioned? How do they add to their understanding of the book?
  • Without reading the main text, have students look only at the text features and make some guesses about what they believe the main text is about.
  • Challenge students to incorporate text features in their next piece of informational writing.

STEM Tuesday — Geology– In the Classroom

STEM Tuesday


This month we’re going to dig into some great books about GEOLOGY! These books will help students learn more about Earth, its surface, structure, and processes. They are a great starting point for different activities and discussions in the classroom. Are you ready to get a little dirty?

Dirtmeister’s Nitty Gritty Planet Earth: All About Rocks, Minerals, Fossils, Earthquakes, Volcanoes, And Even Dirt! by Steve Tomecek
A comprehensive book about geology beginning with the formation of our planet. Chapters cover minerals, earthquakes and volcanoes, plate tectonics, the rock cycle, old dead things (aka fossils) and the importance of soils. Next Gen STEM standards listed at the back.

Classroom activity: Lead a discussion about the rock cycle. How are rocks recycled to create new rocks? Have students create a rock cycle diagram to show what they know. In small groups, students can use wax crayons to create a demonstration of the rock cycle. At the beginning, the crayons represent igneous rock. Next, shave the crayons to simulate weathering. Students can then use the shavings to demonstrate the processes of erosion and deposition. To simulate rock pieces being deposited underground, place some of the crayon shavings in a packet of aluminum foil. Students can then use heat and pressure from their hands to demonstrate the formation of sedimentary rocks and metamorphic rocks. What needs to happen for these “rocks” to become igneous rocks?

Older Than Dirt by Don Brown
Before dirt there was rock. Before rock there was magma. Before that there was – a BIG Bang! This book presents the history of our planet in graphic panels narrated by a couple of wise-cracking characters. They explain tectonic plates, terraforming through volcanic action and faults, and warn that geological activity continues to change the landscape.

Classroom activity: Earth’s surface is made of large pieces of crust called tectonic plates. Throughout Earth’s history, these plates have slowly moved to create the continents, islands, and mountains that we know today. Have students investigate how mountains form and the role of tectonic plates in their formation. Students can create a model or diagram showing what they have learned.

The Scientists Behind Earth’s Processes by Andrew Solway
An evaluation of twelve female and male scientists (1700’s to present day) whose theories and discoveries informed and influenced our knowledge of the Earth. From dating the Earth to climate changes, fossils to earthquakes, continental drift to mapping the ocean, and predicting the weather to exploring space. Includes an interactive timeline showing how they influenced and built off each other’s theories and a “find out more” section.

Classroom activity: Have students choose a geology pioneer to research. What has their chosen pioneer contributed to the science of geology and our understanding of Earth? Have students work together to create a living timeline of geology’s most important discoveries and scientific achievements.

Looking to get even deeper in the dirt? Browse through the pages of these activity books and choose a few to do in class or at home!
