Free STEM Books for Kids
We’re committed to removing barriers to literacy by providing free books that children love. Our STEM books introduce science, technology, engineering, and math concepts to young readers ages 5-9, featuring inventors, builders, coders, and problem-solvers who inspire future innovators.
Birds Like Me Don't Fly
Hank has one enormous dream - he wants to fly! But his wings are small, his body is big, and his feet just won’t leave the ground. When the other birds laugh and say birds like Hank don’t fly, will he give up on his dream? Or could a plank, some tape, and a very big idea change everything? Grab your goggles and find out! This decodable reader practices the nk sound in words like ‘bank,’ ‘clank,’ ‘shrink,’ and ’think.’
Dig, Ned, Dig!
Ned has built a cozy shed in an unknown world, but his magic book says it’s time to dig! Can Ned figure out which end of the shovel goes in the ground? And what happens when his trusty shovel hits something hard and golden deep beneath the hill? Grab a pickaxe and find out! This decodable reader practices the ‘kn’ phonogram in words like ‘knelt,’ ‘knuckles,’ ‘knock,’ and ‘knew.’
Not Again, Dr. Can Do!
Dr. Can Do’s workshop is a disaster zone - redstone dust everywhere, contraptions piled high, and is that a chicken clucking under the repeaters? When he finally decides to tidy up, he spots mountains of extra stone and deepslate that simply have to go. But will a sensible inventor carry it outside, or will Dr. Can Do build something wildly clever instead? This decodable reader practices soft c in words such as ‘place,’ ‘space,’ ‘decides,’ ’notices,’ and ’excellent.’
Don't Mix All Three!
Red, Yellow, and Blue Dinosaur have one colorful job: paint the whole gray neighborhood! Red is bold and fiery, Yellow is sunny and giggly, and Blue has actually read the rulebook. Mix two colors and something magical happens - but what about that one big rule nobody is supposed to break? What could possibly happen if three silly dinosaurs mixed all three colors at once? This decodable reader practices 3+ syllable words such as ‘beautiful,’ ‘dangerous,’ ‘incredible,’ and ‘wonderful.’
I'll Do It Myself!
Jill’s yard is buried under cobblestone, and the line for the village stone bin is massive. Why wait all day when she could just build one herself? With a pattern from Dr Can Do and a chest full of buckets and redstone, Jill marches off to her workshop - but will every piece fall into place before sunset? This decodable reader practices VC/CV syllables in words like ‘bucket,’ ‘pattern,’ ‘sunset,’ and ‘problem.’
Panha Won't Come Down!
Panha’s town is buried under thick, gloomy smog, and she’s had enough! Has anyone ever really seen the sky behind all that gray? When Panha climbs the tallest hill and spots actual sunlight, she races home with a wild idea: invent a plane, fly above the clouds, and bring the sun back. But what will she find waiting up there? This decodable reader practices words with prefixes such as “declared,” “exclaimed,” “replace,” and “unfair.”
Go, Troll Queen, Go!
After a week of rain, the sun is finally out and the wind is perfect - can a homemade kite with a secret weapon really fly higher than every other kite on the street? Follow along as one clever kid measures, cuts, and draws a smiling troll queen onto paper wings, then sends her soaring past the rooftops. Will she rule the whole sky? This decodable reader practices es plurals in words like ‘splashes,’ ‘bushes,’ ‘rushes,’ ‘sketches,’ and ‘reaches.’
Not Done Yet!
Dr. Can Do has a brilliant plan for every cottage in the village - warm carpets, cozy floors, and piles of wool in every color you can imagine! But shearing a whole flock by hand takes so much energy. Could a gentle machine help? And what happens when his friend Jill suggests hiring a villager to run a brand-new Wool Shop? This decodable reader practices soft g words such as ‘gentle,’ ‘huge,’ ‘village,’ ‘gem,’ and ‘imagine.’
Frequently Asked Questions
Why is combining STEM content with reading practice beneficial for young children?
STEM stories make abstract concepts like measurement, engineering, and scientific processes concrete by embedding them in narratives that children can visualize. This builds the background knowledge that Scarborough’s Reading Rope model (2001) identifies as essential for comprehension, while giving children a genuine reason to decode text. Li et al. (2025) found that integrating content-area knowledge with literacy instruction enhances both domains. On Bookbot, every free STEM book is a decodable reader mapped to a phonics scope and sequence.
What free formats are available for Bookbot's STEM books?
All STEM titles on Bookbot are free to read on the website, and many also include features such as read-aloud narration or downloadable PDFs. A University of Chicago study showed that access to a free digital book library significantly improved literacy outcomes for young disadvantaged children, demonstrating the value of removing cost barriers so every child can explore STEM topics through reading.
How do Bookbot's free STEM books support systematic phonics instruction?
Every STEM book on Bookbot follows a structured phonics progression, introducing letter-sound patterns in a controlled sequence so children master each stage before moving on. Ehri et al. (2001) confirmed through meta-analysis that systematic phonics instruction produces significant improvements in word reading and comprehension for children in grades K-3. STEM themes like inventions, simple machines, and coding provide the motivating content while the phonics framework ensures measurable skill growth.
Can parents use STEM books for shared reading at home?
Absolutely. Shared reading aloud is one of the most effective ways to lay the foundations for a love of reading, and STEM stories give families rich material to discuss together. Manu et al. (2019) found that parent-child reading interactions are strongly associated with improved language and literacy outcomes. Many of Bookbot’s free STEM books include a read-aloud mode with word-by-word highlighting so parents and children can follow along and talk about science, technology, engineering, and math concepts as they read.
