STEM Tuesday– Deserts — Book List

From the Antarctic to the Sahara, deserts cover about twenty percent of our planet. Despite harsh conditions, plenty of plants and animals – even people – have found a way to live in the desert.

Weird, Wild, Amazing! Desert: Exploring the World’s Incredible Drylands by Tim Flannery; illustrated by Sam Caldwell

Welcome to the weird wildlife you might find in a desert, from ants to lizards, rattlesnakes to scorpions. Each of the seventeen animal profiles is filled with in-depth and sometimes bizarre facts that highlight issues like climate change and conservation or explain more about evolution and habitats.

A Walk in the Desert (Biomes of North America) by Rebecca L. Johnson, illustrated by Phyllis V. Saroff

A lower middle grade text, this book uses photographs, notebook-like illustrated sidebars, and an engaging text to explore various North American deserts and the ways numerous plants and animals have developed strategies to exist in these challenging conditions. It also explores the interconnected food web and provides ideas for further research.

Keystone Species that Live in Deserts by Bonnie Hinmans

After introducing the concept of keystone species, the photo illustrated book explores the role of the desert tortoise, the addax, Indian vulture, Australian dingo, and guanaco within their desert ecosystems. Resources include extensive footnotes and bibliography, as well as a glossary and index.

Desert (Earth’s Biomes) by Tom Warhol

With a conversational tone and fun photos, this text defines the uniting definition and features of deserts. Then it explores the unique landforms, plants, and animals found in deserts around the world, dividing them into hot desert, temperate deserts, and costal deserts. Concluding with a short discussion about the threats they each face, as well as helpful resources and a glossary.

Desert Ecosystems (Earth’s Ecosystems) by Mirella S. Miller

This is a quick introduction to how deserts are formed and where they are found. Sections focus on animals, insects, birds, and plants. The last two chapters discuss desertification and how people can help save the world’s deserts.

Desert Biomes Around the World by M. M. Eboch

Deserts may be hot or cold, but the one thing they all have in common is that they are dry places. This book looks at deserts around the world and the adaptations that allow plants and animals to survive.

Cactus Queen : Minerva Hoyt establishes Joshua Tree National Park by Lori Alexander

What if you knew a place that was filled with thorny, spiny beauty and dainty wildflowers, but all other people saw was a wasteland? In the early 1900s that’s how people thought of the Mohave desert. But Minerva Hoyt saw the desert as a habitat worth saving, and she went all the way to Washington to let the Park Service know.

Death Valley National Park by Nate Frisch

Death Valley is the hottest, driest, lowest place in the U.S. It’s the place to go if you want to see sunbaked earth, salt flats, and sand dunes. It’s also filled with plants, from cacti to pine trees, birds, reptiles and mammals, and a rich history of human habitation.

Deserts (Explorer Travel Guides) by Nick Hunter

Inviting the reader on an exploration, this lower middle grade book uses engaging sidebars to offer packing and survival tips, amazing facts and figures, descriptions of previous explorers, and conservation notes. Stunning photographs highlight the landforms, plants, animals, and people who live in the deserts. The book also contains interviews with an explorer and a conservationist, a world map, fact file, places to visit, and suggestions for further research.

The Great Victoria Desert (Deserts Around the World) by Lynn Peppas

This is part of an engaging six-book series (largely written by Molly Aloian) which includes the Atacama, Gobi, Kalahari, Mojave, and Sahara deserts. Each book opens with a map, description, and fascinating facts about the specific desert. A discussion of the unique geography, features, plants, and animals is followed by a look at human habitation and development throughout the centuries. They all contain photos, “notable quotations” pertaining to the specific desert, fun sidebars, a timeline, and additional resources.

STEM Tuesday– Survival Science — Christine Taylor-Butler

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

Today I’m doing something different. I’m not interviewing a different author. I’m going to use the time to talk about writing nonfiction and in particular, the books I wrote as part the “Save The . . .” series developed by Chelsea Clinton and Penguin Random House. The reality is, that in studying and understanding these animals, we may in fact, be learning how to save ourselves.

How I got started: I grew up in an inner city environment surrounded by overachieving nerds at a time when the Civil Rights Act was still being debated. Back then I didn’t think much about what it took to survive. All the basic necessities were available. By the eighth grade I had a math teacher, Walter Havenhill. According to him, I was the only student who took his extra credit problems seriously. So he recommended I look into a school called MIT when I was ready for college. Years later, that’s where I received two degrees. It was during that time I realized my life was about problem solving. Back then there were no computers or cell phones. There was paper, pencil and libraries. There was no topic called STEM/STEAM. Everyone tinkered and experimented and created.

As I grew older I saw a shift in the way students were learning. I had been a college interviewer in the evenings. Over time I found quite a few students focused on how to get into a good college by being the “best” numerically. Most read only what was required to pass a test. But there were others, a small minority, who were exploring the world outside of the classroom. They had inquisitive minds and were sometimes looking around their homes for resources to use. Or going out and knocking on doors to find out how they could help on a project. Those are the students I left engineering to write for. Most of my published work is now nonfiction.

Animal survival:  A few years ago, Penguin Random House asked if I wanted to join a group of authors writing books about endangered animals with Chelsea Clinton. The project looked not only at explaining the animals and their survival instincts, but why they became endangered and how their disappearance created unexpected consequences for the human race. Even better, there was a section on how young readers could get involved.  I was all in.

The books are broken into several parts:

  1. Who the animals are and where to find them
  2. What do we know about these animals? What do they eat, where do they live, and how do they raise their young? What are methods they use to survive their environments?
  3. What happened to make them endangered?
  4. The race to save the animals. Who is helping and what can YOU do to participate.
  5. Resources so you can look up some of the information yourself.

Tiger coverIn Save The . . . Tigers. I learned that once upon a time there were enough tigers living in the wild to fill the Roman Colosseum — twice. Think about that. That was about 100,000 tigers. But now there are less than 4,000 among the six remaining species living outside of a zoo or sanctuary. All survive in various parts of Asia, that range from moist hot rainforests, to cold Russian climates.

Tigers are apex predators. That means they are at the top of the food chain and can briefly run faster than a car drives on a street or highway. They are heavy, so they don’t run for long periods of time. Just short bursts. And they sleep a lot to conserve energy for hunts. Mostly during the day. Hunting is hard work. Tigers are only successful in one out of every twenty attempts to catch prey. And yet, tigers don’t tend to eat humans. They’d rather ambush other animals.

But their bodies and furs became valuable to humans. Hunting them for sport reduced their numbers. Humans moving into their habitats to build farms and homes made things worse. It reduced the prey available for tigers to eat as well. Even so, there are now people studying the animals and helping to increase their numbers. And they’re learning a lot in the process. For instance, did you know that tigers (as well as all cat species) have structures in their eyes that we don’t have? That’s why the eyes glow in light at night. Tigers hunt in dark, so their night vision is better than ours. So watch out!

Blue Whales coverSave the . . . Blue Whales was harder because blue whales are rarely photographed. They are the largest mammal living in the ocean. Some grow as long as 110 feet. That is as long as a 737 airplane. But water covers about 70 percent of the planet. And our oceans are very deep. So the whales weren’t easy to find or catch. A lot of what scientists knew initially was from examining dead bodies and guessing. As humans created steam powered ships it became easier to hunt them. Whale blubber was used for fuel and explosives. Other parts of the whale bodies were used for clothing and umbrellas.

Scientists discovered that by reducing the numbers of whales, we hurt the planet. Before they were hunted, whales removed as much carbon from the atmosphere as all the forests on the planet – millions of tons. They ate krill and stored the krill’s carbon in their bodies. You would have to eat 1,000 cheeseburgers to consume the calories a whale eats in a single gulp of krill. And those whales take a lot of gulps per meal. When blue whales dive and poop those actions mix and distribute nutrients throughout the ocean. Now whale numbers are fewer and carbon dioxide on Earth is increasing. Eighty-eight countries have stopped whaling. Three continue to hunt: Japan, Norway and Iceland. There is pressure for them to decrease the amount.

Polar Bears coverLast was Save the . . . Polar Bears. With warming climates these bears are at risk, not because of hunting but because of lack of food and sea ice in the Arctic regions. Most bears can eat a variety of foods. Polar bears are different. They eat mostly seals. One seal can last a polar bear for eleven days. The polar bear body can make fresh water from the seals as well. Also, did you know that a pregnant polar bear can go without food for the last months of her pregnancy? She’s pretty hungry when the cubs are born, so hunting seals becomes a priority. She will teach the cubs to hunt when they are older. When they’re old enough, they’ll move away and start living on their own. But seals live and hide their young on sea ice. With global warming, there’s less of that ice to find. When food is scarce polar bears have been known to enter villages. But that’s very rare.

When I first started researching this book that there were 19 populations of polar bears being studied. But NASA had been secretly tracking a 20th population for several years. Those polar bears were found with the help of indigenous tribes. They didn’t rely on sea ice for survival. Could studying the new population give us clues on how to save all the other groups of polar bears too?

Who is tracking?

There are many organizations, sanctuaries and museums listed in the books. Here are a few to get started.

The International Union for Conservation of Nature (IUCN) keeps track of efforts around the world. They’ve studied 138,000 species so far and rates them based on level of endangerment. There is a significant amount of information on animals you might be interested in studying. The link takes you to their “red list” for endangered animals.

Polar Bears International. They have scientists, Zoom sessions, web cams and tons of information kids might find useful (teachers and librarians too). Too much to describe here.

The Global Tiger Forum is an international group working to conserve tigers in the wild.

International Whaling Commission – has 88 member countries and is responsible for whale management and conservation.

Smithsonian National Zoo and Conservation Biology Institute’s global efforts help save wildlife species from extinction. They train future generations of conservationists at research facilities around the world.

What can you do? There are many ways but here are a few tips to get started:

Recycling is a good easy way to start. A lot of animals are harmed by plastics which make their way into the environment and into the oceans. Better yet, can you reduce the amount of plastic you buy? How about filling a water bottle that can be washed and reused?

Don’t buy clothes or jewelry made from animal parts. That decreases the reasons to hunt animals.

Donate to organizations that help save animals. Even a small amount will help increase animal chances of survival. And the money will help create or sustain habitats that provide a safe environment for animals to raise their young.

Look at ingredient labels on foods and other household items. Avoid ones made with palm oil. Healthy forest habitats are torn down and replaced with palm oil farms. That not only hurts the animals but hurts our environment as well. Forest are like lungs for the planet.

Know that a single individual can make a huge difference in healing our planet. Learning about animals is great way to start. The bonus is that many of their survival skills can prove useful if you’re ever in danger. Where to find shelter, food and warmth. How to avoid predators. Don’t forget, humans are animals too.

STEM Tuesday– Survival Science — Writing Tips & Resources

One often forgets that “Species Survival” can apply to one’s very own environment. My own home is in a thickly populated area – highways, houses and apartments, stores – but nature is still here. Species Survival is more than tigers and whales. It also applies to the species we take for granted because we see them every day, including insects, small animals, native plants, and – the focus of this post – trees.

I find many of my friends have no idea what kind of trees they see and encounter. A project for classroom or life is learning to identify trees. There are lots of resources. I found this fabulous, friendly book, published in 1963, and still available. Tree Finder: A Manual for Identification of Trees by Their Leaves (Eastern US) is currently available at Indiebound. The illustrations are charming and would be very helpful to anyone wanting to learn about trees. It’s a good size to carry around with you.

Tree Finder Book

Another resource is The Sibley Guide to Trees, by David Allen Sibley. There’s a lot of reading but you can find other tree identifiers besides leaves, useful if you are looking in winter.

Sibley Guide to Trees book

The US Forest Service provides lots of technical information about the state of trees and forests. I was able to find a whole section of tree material at https://www.fs.usda.gov/learn/trees. In addition, they have many publications for different localities. I was able to find Southern New England Forests to research trees in my own area.

A fun and useful project with leaves is leaf printing. You can make paintings, wall hangings, journal pages, even tee shirts, depending on the ink you use. The basic method is to roll the ink onto a leaf and then with a brayer, spoon, press, or baren transfer the leaf pattern to the surface where you want the image.

There is plenty of information about leaf printing online, and here are some books are linked below.

An activity for both adults and kids is a tree journal or a nature journal. No particular artistic ability is needed because it can be filled with casual sketches, notes, materials pasted in. In the interest of species survival, I suggest a notebook or sketchbook made from recycled materials. Some places are listed below.

A nature notebook would follow in a long line of past documenters of nature. Beatrix Potter, the creator of Peter Rabbit, was a dedicated nature journalist. Her exceptional artwork, along with a dedication to preserving England’s rural history, has contributed to preserving the beautiful countryside in the Lake District.

Claire Walker Leslie has many books out on journalling. I attended a workshop with her many years ago and was greatly influenced. I have kept visual journals ever since. I highly recommend Keeping a Nature Journal, 3rd Edition: Deepen Your Connection with the Natural World All Around You. The value of keeping a journal goes beyond documenting your world, it provides a creative outlet that often helps almost as a form of meditation and contributes to mental and emotional well-being.
