STEM adventures for curious kids ages 4–8 — set right here in the harbor.
Every Propeller Pals story entertains first — and teaches second. No lectures. No talking down to kids. Just great adventures.
Each book teaches one real engineering concept — propulsion, buoyancy, navigation — through story, not slides.
Tuggy, Heli, Connie, Drifty — each pal has a real job, a clear personality, and a team to depend on.
Calm pacing, gentle problem-solving, and a satisfying finish — the formula for a book kids ask to read again and again.
Each Propeller Pal lives and works in Propeller Town — a bustling harbor city where every vehicle has a story.
The Helper of the Harbor
Small but mighty, Tuggy guides big ships safely to dock. Teaches: propulsion & push/pull forces
Coast Guard Helicopter
Always ready to respond, Heli spots trouble from the sky. Teaches: lift, rotation & rescue
The Containership
Connie crosses oceans carrying cargo from all over the world. Teaches: global trade & navigation
Fan Boat Explorer
Fannie glides through the wetlands on a cushion of air. Teaches: ecosystems & air thrust
The Curious Drone
Drifty sees everything from above and loves to learn. Teaches: observation & technology
C-17 Transport
Pete carries big loads and works with the whole team. Teaches: aviation & logistics
"Tuggy Tug's Big Day" — a 24-page board book where Tuggy helps a giant ship dock safely in Propeller Town harbor, learning all about propellers and teamwork along the way.
Format
24-page board book, 8"×8"
Ages
4–6 (early reader 6–8)
STEM Focus
Propulsion & push/pull forces
Every story embeds one key concept from real engineering, navigation, or marine science — the way kids actually learn: through characters they love.
Spinning blades push water or air backward — which pushes the vehicle forward. Newton's Third Law, made simple.
Buoyancy, displacement, and hull design — the science of floating told through Connie and Tuggy's adventures.
Left and right, compass directions, reading maps — practical skills woven naturally into every adventure.
Lift, rotation, and hover — Heli the Coast Guard helicopter shows kids the science of staying up in the air.
Fannie's marshy home is full of life — birds, fish, and plants that depend on each other, explored gently story by story.
Every problem in Propeller Town is solved together. Engineering thinking + cooperation = every good adventure.
Propeller Pals books are designed to align with NGSS and Common Core early learning standards. Free activity guides, coloring pages, and classroom discussion prompts are available with every title.
Propeller Pals books are designed for children ages 4–8. Board book editions are ideal for ages 4–6, with early reader editions coming for ages 6–8.
Each story teaches one clear STEM concept — like how propellers create thrust, why boats float, or how helicopters lift off — through fun, gentle adventures. No lectures, just great stories.
Propeller Town is a fictional harbor city inspired by Charleston, South Carolina — full of boats, cranes, helicopters, fan boats, and all kinds of propeller-powered vehicles.
