In John Himmelman's early chapter book series, Albert Hopper is a frog—and a science hero! He seeks to explore the world and beyond, generating laughs and imparting STEM wisdom as he goes.

Albert Hopper, Science Hero is on a mission: to travel to the center of the earth! With his wormlike ship Wiggles and the help of his niece and nephew, trusty Junior Science Heroes Polly and Tad, Hopper is ready to go where no frog has gone before.

Thick layers of rock and rubble, tunnels of lava, and temperatures of 6,000 degrees stand between our heroes and their prize. Will they make it? Find out in this funny and informative adventure.

Chapter 1


“Calling Junior Science Hero Polly. Calling Junior Science Hero Tad. Report to the laboritorium, and quickly!”

Polly and Tad raced to their uncle’s lab. A huge metal worm filled the room.


Praise for Albert Hopper, Science Hero

"A ground-shaking, pulse-pounding journey to the Earth's core and back (with a few side trips along the way). In typically grandiloquent tones—"We shall be…WORMING TO the CENTER OF THE EARTH!"—froggy explorer Albert Hopper invites Junior Science Heroes (and niece and nephew) Polly and Tad on a voyage of danger and discovery aboard aptly named mechanical drill Wiggles . . . . Will leave readers eager to…GO AGAIN!" Kirkus Reviews -
