Book Review: Once in a Blue Moon

Kids all seem to go through a phase of loving trivia, and if you’ve got kids who want to know about the tallest, biggest and weirdest things in nature, they’ll enjoy the book Once in a Blue Moon by Emily Hawkins.

The book explores wonders of astronomy, meteorology, big trees, weird animals, volcanoes and more to show off the rarest events and phenomena in the natural world.

Kids ages 7-10 will learn about the lake (Lake Hillier, on an island off Australia) that has water that’s bubblegum pink, the world’s deepst came (Veryovkina Cave in the country of Georgia) and the world’s biggest tree, a banyan in southeast India with a canopy that covers more than five acres!

Readers will learn what a blue moon is, how supernovas happen and about Haley’s comet and solar eclipses, among other space-related phenomena. Closer to home they’ll learn about stinky flowers, bleeding trees, glowing fungi and pizzly bears.

There’s content about times when it’s rained frogs (and when frogs have exploded en masse), when snow made giant snowballs all by itself and how clouds stack on themselves like pancakes. The book also explores ball lightning, sun dogs, St. Elmo’s fire and more.

I love books like this and I know kids do, too. There’s so much weird and wonderful about our world and even as adults we don’t know about all of these things. I found it fun to learn, for example, that there’s a volcano on the island of Java that not only sends out blue flames from vents near its crater, it’s also home to an acidic lake.

Illustrations by Vlad Stankovic illuminate these weird natural wonders and are sure to get kids interested in learning more about some of these remarkable animals, plants, rock formations and more.

About the book: 80 pages, hardcover. Published 2026 by Wide Eyed Editions. Suggested retail price $30.

Ghost crafts are a lot of fun for kids to make and they’re a way to get into Halloween crafting that’s not really scary. Here are some easy ghost crafts for you to make with kids, whether it’s your kiddo at home or a class full.

I love this simple ghost made with a pompom or cotton ball covered in paint and used as a stamp. This one is from Crafts on Sea and you can have kids just hold the pompom or hold it with a clothespin to make it a little less messy.

Use cotton balls and printable facial expressions to make these silly ghosts from Housing a Forest. The post includes the printable templates or you can just add googly eyes.

Little fabric ghosts are a classic, whether you make them with white fabric or fall or Halloween fabric. Buggy and Buddy shows you how to make these little ghosts with a few cute embellishments. Just make one or two or make a garland or Halloween tree full of them.

There always seem to be paper plates lying around, and this paper plate ghost from Crafts by Amanda is a fun one. There’s a printable in the post for the facial features and arms, or kids can draw their own faces (and leave off the arms if you want to keep it simple).

What kid doesn’t love peeling dried glue? Turn that impulse into a craft with these glue ghosts from Friends Art Lab, and don’t miss the tip in the post that helps you turn these into window clings.

This handprint ghost in the window craft from Glued to My Crafts is so cute and easy for kids to make alone or with help. The post shows lots of variations so it would be fun to make these in a classroom and let each kiddo design their own “window” or add embellishments.

These sweet little tissue paper ghosts from Red Ted Art are actually mini pinatas, but you can just make it as a ghost without anything inside if you’d rather.

And you know I love a good kids’ sewing project so I can’t resist sharing these little felt ghost puppets from The Craft Train. Kids can sew them by hand or you can make them out of paper if you don’t want to try sewing them. The template for the ghosts is free to download, and you can also just make little softies instead of puppets if you like.
