Bam! Ka-boom! Bu-u-urp! The Carbon Cycle

 
From BAM! to BURP!: A Carbon Atom's Never-Ending Journey Through Space and Time and YOU 
by Melissa Stewart; illus. by Marta Alvarez Miguens 
40 pages; ages 5-8
‎Charlesbridge, 2025

themes: atoms, carbon cycle, science

You’ve probably heard of atoms. They’re the tiny particles that make up almost everything we know in the Universe (including you).

Here’s the thing about atoms: they never disappear. They just keep moving from one thing to another, from one creature to another … from leaves to dinosaurs to fish to … us!

Melissa Stewart takes readers on a journey through the carbon cycle, beginning with a big crash (that’s the BAM of the title) – when a small rocky planet crashed into Earth. Bits of that planet melted, and the atoms (including carbon) rearranged into new molecules – like carbon dioxide spewed out of the cone of a volcano during eruption. In her book, Melissa shows that molecule eventually getting sucked up by a leaf. Once the carbon dioxide is broken down, that carbon atom is used to make glucose – hooray for photosynthesis! And carbon is happy – whoops! I spoke too soon because a long-necked dinosaur just came by and ate that leaf!


What I like about this book: I like how Melissa makes the journey of a carbon atom seem like such an adventure. And how she asks readers to think about where a carbon atom they exhale or burp might go next. I like the “Wonder Wall” she has at the end of the book – a wall full of post it notes with questions (and, thankfully, answers). Additional back matter explains more about the carbon cycle, fossil fuels, and climate change.

After reading this book, I had One Question for Melissa:

Me: In your author note you mention that a kid's question inspired you to trace the path of a carbon atom from us all the way back to dinosaurs and beyond. And this isn't the only time a kid's question has inspired a book (I think aardvark started that way?) - can you talk about the value of listening to the questions kids ask and how they've inspired your own curiosity?

Melissa: I like your question a lot! Yes, my book Can an Aardvark Bark? was inspired by a question from my nephew, Colin. Key aspects of Thank You, Moon and Summertime Sleepers also trace back to experiences with my niece, Caroline, and my nephew, Emile, respectively. Since children are my audience, I always pay close attention to their opinions and ideas. What excites them? What makes them curious? What leaves a lasting impression? I want to understand how they see the world and their place in it, so that my books will truly resonate with them.

Beyond the Books:

Make a list of things you find in your house and around your yard that have carbon in them. (hint: living things have carbon, some rocks have carbon)

Experiment with Fizzy Drink science! You need some fizzy drinks (diet cola works) and some mints (mentos work) and a place where it’s okay for messy science to happen. Here’s a video about carbonation science.

Got rocks? Some rocks, like limestone, have carbon atoms in their make-up. You can test whether rocks have carbon in them by dropping some hydrochloric acid – or even strong vinegar – on them. If they have carbon, they will fizz or foam. Those hard water deposits on your tea kettle are probably calcium carbonate. Go ahead – toss vinegar on them to test. Another good source to test for carbon: baking soda!
