Big Bertha: How a Massive Tunnel Boring Machine Dug a Highway under Seattle, by Amanda Abler/Illustrated by Katy Wu, (Sept. 2024, Little Bigfoot), $18.99, ISBN: 9781632173065

Ages 7-10

Have an emerging middle grader who loves reading about heavy machinery and vehicles? Big Bertha is the book for them: an earthquake rocks Seattle, Washington in 2001, damaging an elevated highway by the city’s waterfront. If another quake were to hit, the roadway could be at danger of collapsing. The decision was made to replace the highway with a double-decker tunnel running underneath the city. Bertha is the huge tunnel boring machine – the height of a 5-story building! – built in Japan and brought to Seattle to dig and build the tunnel. Named for a former Seattle mayor, Bertha is depicted as massive; readers will be amazed at her scale and power. Deputy Project Manager Greg Hauser and his crew, dedicated to the project, took sleeping shifts and stayed with Bertha all the way, even sleeping in shifts to stay with her as she worked. Do you know kids who love building with LEGO and blocks? Do they construct cities in Minecraft and Roblox? Readers interested in engineering and heavy machines will be fascinated by Bertha, who “chewed up dirt and boulders, removing the earth ahead of her” while her “red erector arms pieced together arcs of concrete to form the outer walls” of the tunnel. Back matter includes a photo of Bertha and her crew; numbers, and facts about the machine and the construction.

Big Bertha has a starred review from Booklist.

 

For the future marine biologist:

Narwhal: Unicorn of the Arctic, by Candace Fleming/Illustrated by Deena So’oteh, (Oct. 2024, Anne Schwartz Books), $18.99, ISBN: 9780593377789

Ages 4-8

Is there anything Candace Fleming can’t do? She writes picture books, novels, fiction, non-fiction, and she’s a conservationist, making her a super human being in my book. Fleming’s newest work is a lyrical piece about a year in the life of a narwhal. Fleming combines nonfiction description with storytelling verse, with playful descriptions – “You are… . shy, / swift, / small (for a whale)” and detailed: “your tusk… / a single / twisting / rod of ivory / that sprouts from your upper left jaw”. The narwhal moves with his pod through the seasons, following food and avoiding danger. So’oteh’s digital illustrations bring the clear cold of the Arctic to beautiful life, with brilliant blues and greens and murky blues showcasing the underwater world. A gatefold displays an incredible narwhal pod dive that will delight readers, and near escapes from a pod of killer whales on the hunt, being stuck under the ice, and discovery by a polar bear! This is picture book nonfiction done spectacularly well and is perfect for readers who love animal stories.

Narwhal has starred reviews from Publishers Weekly, Kirkus, Booklist, and Horn Book.

 

For the stargazer:

The Mathematics of the Universe, by Soledad Romero Mariño/Illustrated by Renee Hao, (Oct. 2024, Schiffer Books), $18.99, ISBN: 9780764368387

Ages 5-9

Verse, quotes, and beautiful illustrations come together to explain the patterns of our universe, from the spiral of a snail’s shell to the swirl of a galaxy. It’s a beautiful introduction to STEM and mathematics, inviting readers to explore concepts like spheres and hexagons, symmetry and spirals, and inviting readers to look closer at nature and unpack the mysteries they see: “The universe seems in such disarray, / but it follows an order, not one thing astray”.

Want to show your readers more about mathematics in nature? The Carnegie Museum of Natural History has some great photos that explain these concepts, too!
