Right in time to celebrate Women's History Month we have two brand new picture book biographies of women pioneers in STEM. For Nonfiction Monday, let's start with The Stuff Between the Stars: How Vera Rubin Discovered Most of the Universe by Sandra Nickel and illustrated by Aimée Sicuro. We liked this one so much, we're offering a giveaway in the Rafflecopter window below.

About the Book:

Vera Rubin was an astronomer who discovered some cool and important "stuff".

From a young age, she was captivated by stargazing.

As she got older, she began to investigate swirling clusters of stars, gases, and dust known as galaxies.

She studied where galaxies were found in space and how they moved relative to each other. When she saw the stars within galaxies move at different speeds than she thought they should, she demonstrated there was something in between the stars that we can't see or detect, something pulling the stars. That "something" had been previously named dark matter and there is a lot of it!


In addition to revealing groundbreaking science, author Sandra Nickel also celebrates Vera Rubin's passion for her work and how she kept going in spite of numerous obstacles, including others not understanding her work.

It is not easy to explain big concepts like galaxies and dark matter for young readers. Sandra Nickel has nailed it.

Aimée Sicuro's illustrations are out of this world. They vacillate between concrete and abstract, contrasting how grounded Vera was even when her thoughts were in the galaxies. You can see what I mean in the page spread below.

If you are a regular reader, you know how we love back matter and this book does not disappoint. It includes an Author's Note, which puts Vera's discoveries in context, a Timeline of Vera Rubin's Life, Notes about quotes used, and a Selected Bibliography for young scholars who want to delve more deeply.

The Stuff Between the Stars is sure to thrill budding astronomers. It would be perfect to accompany a trip to a planetarium, as well as for Women's History Month discussions. Gaze into a copy today!

Activity Suggestions:

    1. NASA Space place as a fun Galaxy Pinwheel to print out and make, as well as more information about what a galaxy is and more about dark matter.
    2. Galaxy jar craft:  Sandra Nickel describes the movement of stars in a galaxy as "like glitter caught in an invisible halo." Check the internet for instructions for a galaxy jar craft that involves swirling glitter in a paint-filled bottle or jar. One example at Crafty Morning.
    3. Find more biographies of Women in STEM at Science Books for Kids.

Today's featured title, 13 Ways to Eat a Fly by Sue Heavenrich and illustrated by David Clark, just came out last week and already there's quite a buzz about it. Let's find out why.

This fabulous picture book puts both the S (science) and the M (math) in STEAM. And a bunch of silly A (art), too.

The story starts with a cloud of thirteen different kinds of flies.

Big flies,
small flies,
fat flies,
Yum! These flies are someone's dinner.

As they travel through the book, the flies meet one untimely end after another as the reader learns about all the living things that rely on flies for their survival.

13 Ways to Eat a Fly has tidbits for everyone. The youngest readers will enjoy counting down the numbers. Slightly older readers will enjoy the gross and silly aspects, such as the absolutely hilarious chart of the edible parts of a fly along with a graphic listing the nutritional facts. Budding entomologists will soak up all the science, including the common and family names of each of the flies, interesting details about the predators, and an introduction to food chains. Educators will enjoy two pages of suggested books and websites in the back matter, so helpful for digging deeper.

Not sure you really want to read about icky flies? Don't worry, by the time you're done, you will be rooting for them!

Ever wondered how an author gets an idea for a book? You're in luck. This week I talked with author Sue Heavenrich by phone. Be a fly on the wall for our conversation!

You’ve written a book about insects for children. Were you interested in critters when you were young?

When I was a kid, I kept a notebook of organisms - sort of like a "life 
list" birders keep, but with animals and plants that I got to know. I
 loved to make lists: all of the kinds of squirrels found at the Grand
 Canyon; the different kinds of trees at the Girl Scout camp; what the
 black widow spider living in my window ate for breakfast (don't tell my
 mom - she still does not know about that spider!) So I am thinking it's 
not a surprise that I would begin to write a book about flies by making
 a list of flies seen in and around my garden.

That is so cool. Keeping a notebook and making lists are great tools for learning. Where did it take you?

I got my master's degree in biology working on insect behavior studies with Michael Breed at U of CO, Boulder. Two of the papers I published (My name was Susan K. Smith at the time):

  1.  In Animal Behaviour
  2.  In Physiological Entomology

It is fascinating that you studied cockroaches (I’ll have to tell you my cockroach stories some time.) Right now, I’d love to hear more about the garden you mentioned.

I have a vegetable garden. It is not so much about growing food, but it is a place to observe and learn about other living things. Definitely about the woodchucks, chipmunks, and beetles!

A few years ago I got involved with the  Great Sunflower Project, a citizen science study facilitated by Gretchen (LeBuhn). We grew sunflowers and counted the bees and other pollinators that visited. As a result, I got into gardening for bugs.

I grow plants with the aim to attract native insects and my yard has dandelions, violets, buttercups, etc. I enjoy looking closely at the insects that visit. I am especially fond of bumble bees, which are the teddy bears of the bee world.

Once I found an insect that looked like a hornet, but something was not quite right. It had two wings and the antennae looked wrong for a wasp. Turns out it was a fly that mimicked a hornet. That made me start thinking about the diversity of flies, and you guessed it, eventually led to the book.

We are thankful for that fly!
Besides in the garden, where else can we find you?

I blog about science and STEAM books at Archimedes Notebook
( and folks can visit me at my website

Thank you so much for your insights and sharing your interest in flies. Maybe some day we will all have gardens for flies.

Activity Suggestion:

Start a fly or insect notebook like Sue did. This can be a paper notebook or if you are older and have a phone, you can use apps like iNaturalist.

Keep records of the flies you see. Make a list of common and scientific names. Find out more about each type of fly in books or websites like the ones listed in the book.

If you like to draw, add illustrations to your notebooks. Drawing requires close and accurate observations. It is a useful skill. You can strive for scientific accuracy and have fun like David Clark did.

If you have a camera, you might want to take photographs. I keep photographic records of the flies I see around my yard in this blog.

Think flies are bland and boring and only eat garbage? Check these out!

Bottle Flies - Family Calliphoridae (prev. post)

Fun fact:  Bottle flies pollinate specialized carrion flowers like Stapelia (previous post).

Long-legged flies (Dolichopodidae)

Fun fact:  The adult flies are beneficial in the garden because they are predators of other small insects like aphids and leafhoppers, as well as spider mites (previous post).

Crane flies (Tipulidae)

Fun fact:  Although they may superficially look like giant mosquitoes, crane flies in a completely different family. They are fragile insects, not harmful in any way (previous post).

Bee Flies (Bombyliidae)

Fun fact:  Like bees, bee flies are pollinators. They use their long mouthparts to suck up nectar from flowers (previous post).

Hover or Flower Flies (Syrphidae)

Fun fact:  Adult flower flies pollinate flowers and the larvae eat aphids. Win-win!

Featured in the book:  Mediterranean fruit fly (Tephritidae)

(Photograph by Alvesgaspar at Wikimedia)

Mediterranean fruit flies are potentially invasive pests. Some states, particularly California, have extensive monitoring programs. If even a single fly is found, they spring into action to prevent it from taking hold.

Fruit flies (Drosphilidae)

Can you tell this regular fruit fly from the Mediterranean one above? Hint:  Flies in the family Tephritidae are also sometimes called "picture-winged" flies. Let us know the differences you see in the comments.

This family of fruit flies are not in the book, but are important. The study of fruit flies has led to incredible scientific advancements in the fields of genetics and embryology.

Fun fact:  Fruit fly larvae consume fruit that is rotting or fermenting. They eat the fungi/yeasts in decaying fruit as an important source of protein ( Nature article, previous post, previous post with life cycle).

So, do you think flies are cool now?

Today we are participating in a blog tour for the fabulous new picture book biography The Leaf Detective: How Margaret Lowman Uncovered Secrets in the Rainforest by Heather Lang and illustrated by Jana Christy. I'm so excited about this book, I'm offering a giveaway via Rafflecopter below.

If you are familiar at all with rainforest biology, you know that the forests are structured into layers.

The Leaf Detective book is as multilayered as a rainforest.

The trunk of the book is the biography of Margaret Lowman, an incredibly brave and determined biologist who developed new methods for studying the tops of trees, the canopy and emergent layers. Using ropes and a harness of her own design, she climbed up into the great unknown.

We had already been to the moon and back and nobody had been to the top of a tree.

The branches of the story are Meg Lowman's findings. For example, she discovered that most of the herbivores in the rainforest she studied were nocturnal, eating leaves at night and hiding during the day. To learn more, she climbed up into the trees at night.

The roots of the story comes after Meg realized that for all people didn't know about trees, they were still destroying them at an alarming rate. She started to come up with innovative ways for people to use intact forests as a source of income and thus making it economically viable to save them.

Let's not forget the leaves. Sprinkled throughout are leaf-shaped sidebars filled with interesting facts and additional details. So cool!

The illustrations are as green and lush and complex as a rainforest, too. The reader could get lost and spend hours in them. My favorite shows Meg sitting in her office, but the wall has disappeared and has become part of the natural world outside. It emphasizes that we aren't separate from the natural world, but we are part of it.

The bottom line? The Leaf Detective is perfect for young readers who are budding scientists, adventurers, conservationists, interested in women's history, the list goes on and on. Pretty much everyone will find something to explore in it. Pick up a copy and see how it resonates with you.

Activity Suggestions to Accompany the Book:

1. Investigate Leaf Age

One way Meg Lowman studied trees was to investigate leaf ages.

In areas where trees lose all their leaves in the fall, leaf age isn't a big question. However, some trees may be evergreen, or in warm climates may keep their leaves year around.

If you’d like to find out how long the leaves live on trees or shrubs in your neighborhood, choose some freshly emerged leaves and mark them with an acrylic marker. The young leaves are a lighter, brighter green color and are often softer in texture.

If you don't have a marker, you could also mark the leaves with tags or ties, anything that won’t wear or fall off or interfere with normal leaf development and photosynthesis. Record how many leaves you tag, when you tag them, and roughly where they are in the tree.

Check your leaves periodically. You might want to mark more leaves each time if you see new, fresh ones. This is a long-term project, so be patient.

We marked some of the new leaves on our lemon tree, which is evergreen here, a few years ago. Our marked leaves remained on the tree through one entire year. The tree dropped a lot of leaves a couple of times, but our marked ones held on. Unfortunately, our marked leaves were lost before the experiment was finished when someone -- who didn't know about our experiment -- trimmed the tree.

Let us know what kind of tree or shrub you choose and how long the leaves last.

2. Be a Fallen Leaf Detective

If you live in an area where the leaves come off in the fall, you can do a lot of leaf investigations. For example, you can figure out which leaves came from which trees.

Gather a good tree identification guide that shows both leaf shape and bark patterns. Identify the leaf by its shape, then find the tree by its bark pattern, color, and general shape.

Start with some trees you know well to practice then move on to unknowns. Remember that leaves blow around. Look for nuts/seeds to match with the trees that produced them, as well. Treat it like a game.

During a quiet moment, take a good look at the trees. Once the trees have lost their leaves, other aspects of their structure are revealed, such as the texture of the bark, the shape of the branches, even the leaf scars on the twigs. Compare different trees. Close your eyes and feel the bark. Listen. Smell the wood. Do trees smell differently? Talk about your findings.
