Building Children’s Science Identities One Notebook at a Time ~ by Jessica Fries-Gaither

 I’ve loved the natural world my entire life. Thanks to a childhood full of hikes in metro parks, afternoons splashing in creeks, and workshops at a local science center, I grew into an adult who enjoys sharing these wonders with others. Becoming a science teacher was a natural step after I decided that the research life wasn’t for me. And eventually my other lifelong love—reading—caught up and led me to extend my influence beyond the walls of my classroom by writing my own books. 

In my 23 years as a science educator, I’ve become increasingly convinced that simply teaching science content is not enough. Rather, we need to help children build identities as scientists themselves. Being able to recite all the concepts and vocabulary in the world means little if kids can’t see themselves in science and see science as relevant to their lives. 

Here's something else I know to be true: while children don’t bring the traditionally accepted body of scientific knowledge to their interactions and explorations with the natural world, they are indeed scientists. Spend any amount of time with a curious preschooler and you’ll witness many sophisticated science and engineering practices at work: asking questions, testing variables, and iterative problem solving. 

Sadly, traditional means of schooling can drum the curiosity right out of kids. And the problem is only compounded when science is presented as the domain of dead white men. How can we better structure experiences both in and out of school to help students bolster their scientific identities? One of the most powerful practices I’ve discovered to link students to scientists is keeping a science notebook.


Anyone who pursues science for a career or a passion keeps records of some sort. Chemists, molecular biologists, geneticists, and others keep lab notebooks which record their experimental methodologies, data, and analysis. Ecologists, paleontologists, and geologists keep field journals which detail observations and findings on location. Even citizen scientists and hobby birdwatchers document their findings in notebooks or digital apps. The documentation of procedure and findings is an essential practice of science for a variety of reasons: archiving results for future reference, replicating experiments, and sharing findings with others.

Science educators often have students keep science notebooks as well. But simply requiring the notebook isn’t enough. To maximize on the identity-building potential of a notebook, students must understand that they are engaging in the same practice as that of professional scientists. Want students to record observations through sketches? Read about John James Audubon, Beatrix Potter, or Charles Darwin and view samples of their notebook pages before starting on your own. Need to focus on modeling? Galileo’s notebooks might hold inspiration. Planning experiments? Read about Charles Henry Turner’s groundbreaking work with insects. 

The recent explosion of picture book biographies provides a terrific opportunity to help kids make connections between their own work and that of scientists. I created a [partial] list of picture book biographies and their correlations to science and engineering practices from the Next Generation Science Standards on my own blog and try my best to keep it updated.

Additionally, my first picture book, Notable Notebooks: Scientists and Their Writings (NSTA Kids 2016), profiles a diverse group of historical and contemporary scientists and engineers for whom notebooks are an essential tool. There are some recognizable names (Galileo and Newton, for example) mixed in with unfamiliar ones (Lonnie Thompson), and ones that you might not have known were scientists at all (Beatrix Potter). Linda Olliver’s beautiful illustrations make the scientists come alive, and the addition of photographs of actual notebook pages are sure to intrigue readers. In one of those “I can’t believe this is my life” moments, my book was sent to the International Space Station and read aloud by astronaut Joseph Acaba through the Story Time from Space program. The video is available on the Story Time from Space website and is perfect for sharing with children at school or at home.   

For teachers looking for more guidance in this area, I published a book on the topic this year. Science Notebooks in Student-Centered Classrooms (NSTA Press 2022) is a practical and research-based guide to implementing a notebooking practice and a testament to how science notebooks support a sensemaking culture in elementary classrooms. 

It’s worth noting that science notebooks aren’t just for school. Explorations of science and nature happen outside of the classroom, and parents can encourage children to keep records of what they are doing and learning. Homemade notebooks with a few pieces of paper stapled together work just as well as a notebook purchased from the store. Read Notable Notebooks together, talk about the ways that scientists use notebooks in their work, and then put it into practice. Sketch the worm wriggling through the garden, or write the steps for creating that perfect batch of slime. Take that notebook on a visit to a local park or the beach, and encourage kids to draw, describe, question, and investigate. Give them time to share their work and reinforce the idea that by keeping their notebooks, they are, in fact, acting as scientists.

The notebook pages featured in this post come from Jessica's students.

Messing around in my Nature Journal

 Have you ever smooshed a marigold or buttercup across a page in your journal or sketchbook? Maybe it left a yellowish smudge… And while you may have done it by accident, a couple weeks ago I smooshed plant parts onto the page on purpose.

It was part experiment, part “artist date” a’la Julia Cameron, and a whole lot curiosity. I wanted to know would blue pigments in my bachelor button blossoms smear blue pigment on the page? Would the centers of oxeye daisies make as nice a yellow as buttercups?

Materials
I began by collecting a variety of plants that I thought might provide some color:

bachelor button flower
bleeding heart flowers and leaves
oxeye daisy flower
buttercup flowers and leaves
yellow hawkweed flowers
creeping charlie leaves
wild strawberries

Method
 I knew I could extract pigments by boiling the flowers and adding a mordant (a mordant is a chemical that helps keep the pigment from fading, such as vinegar or alum). But I wanted something more immediate. So I pressed and smeared, smooshed, and squashed petals and plant parts directly onto the paper.


Results: Yellow hawkweed and buttercup petals left bright yellow smudges; the yellow center of the daisy left only a faint mark. Bachelor button petals left a bright blue. Strawberries left pink smears, not the red I expected. Bleeding heart flowers left no pigment on the page. As for the leaves, creeping charlie and bleeding heart leaves left different shades of green.

Charlotte the Scientist is Squished

Charlotte the Scientist is Squished
by Camille Andros; illus by Brianne Farley
40 pages; ages 4-7
Clarion Books, 2017

themes: investigation, science

Charlotte was a serious scientist.

She's got a lab coat, protective glasses, a magnifying lens, and a clipboard for important notes. What she doesn't have: space to do her experiments.What does she expect? She's a rabbit, so of course she's going to have lots of brothers and sisters living with her.

So Charlotte puts her scientific method to use to solve her problem. She starts by asking a question. Then she forms a hypothesis: If I can get rid of my brothers and sisters, I will have room to be a scientist. To test her hypothesis, she conducts an experiment - or two - which don't quite end the way she hoped.

Time for Plan B: if she was going to get some space, she would have to go there. To space. And when she gets there, she has lots of room for all her experiments. There's only one problem: Charlotte misses her family.

What I love about this book: what a fun way to introduce kids to the scientific method! There's great  back matter, including a list of the steps of the scientific method. I also love the end papers, which are blueprints of her space lab. And I like how Charlotte finds the solution to her problem.

Beyond the book:

Do Science!  Make some kites and fly them in the March winds. Experiment with kite shapes and tails, size and weight, materials (can you make a kite out of stuff from the recycling bin?). Try flying kites under different conditions. 

Keep a Question Notebook - someplace you can write down questions you have. Like how do birds fly when it's windy, and can you teach bumblebees to drink sugar water from a jar lid?  Leave some room beneath the question so you can scribble ideas for how to find out the answers. Then use the scientific method to find the answers.

Meet the Author: Scientists sometimes get their ideas from strange places. Author Camille Andros says she got her idea for this book while in the shower. Here's an interview with the author.

Today is Perfect Picture Book Friday, an event in which bloggers share great picture books at Susanna Leonard Hill's site. She keeps an ever-growing list of Perfect Picture Books. Review copy provided by publisher. It should hit bookstore shelves early next week.

Never Insult a Killer Zucchini!



Never Insult a Killer Zucchini  
by Elana Azose & Brandon Amancio; illus. by David Clark
32 pages; ages 7-10
Charlesbridge, 2016

Topics: alphabet, science experiments, humor 

Opening: “I grew zucchinis when I was a boy. They’re my favorite!”

It’s time for the science fair and Mr. Farnsworth is the judge. When the killer zucchini hears Mr. Farnsworth profess his love for zucchinis, it falls in love. Maybe Mr. Farnsworth could be a friend? But when Mr. Farnsworth says, “He looks like a yummy afternoon snack,” all bets are off. The killer zucchini is determined to squash Mr. Farnsworth and stay off the menu. And it uses the science fair experiments to exact revenge until chaos breaks out and only Mr. Farnsworth can save them all. 

What I like about this book: I like that the story is told through dialog balloons and comic-book type illustrations. I also like that the outrageous science fair experiments are introduced in alphabetical order. I love the whimsy of the illustrations, too.

But what I really like is the back matter. “Think the projects in this book are just mad science?” ask the authors. Nope; they all come from the real world – even the “eraser beam” and “invisibility suit”. Each experiment is explained in the back using language that we comic-book readers can understand. 

Beyond the book: Think of the weirdest science experiment someone might want to try. Then find out if anyone has tried it! Antimatter experiments? Yup, being done. Killer zucchini? Not so much, although there are plenty of carnivorous plants. Here’s a video. 

Do some science. You can find experiments at this site. And this one. 

Make some goop! Just follow these instructions.
