Fred Flintstone's Adventures with Wedges

Fred Flintstone's Adventures with Wedgesis part of a Simple Machine series starring the Flintstone's characters.

This series breaks down the individual components of simple machines into separate books. The focus is for younger readers and the text, dialogue and pictures are designed to introduce, define, and provide examples of wedges. The book does a great job introducing the concept and provides some interesting examples to help young readers understand what a wedge is and how to identify one.

Fred discusses door wedges, wheel chocks, axes, nails, chisels, darts, knives, and teeth. Each is illustrated and the characters explain why these fit the definition of a wedge.

My one question about this series is name recognition. I loved the Flintstone's as a child. However, talking to my niece's boys they don't seem to know much about them. Parents might enjoy sharing their memories of the series with their kids. I'm just not sure if the connection will be the same if there isn't a connection to the cartoon.

The Fort on Fourth Street

The Fort on Fourth Street: A Story About the Six Simple Machinesis a great concept for teaching simple machines, but it didn't quite deliver as strongly as I'd hoped. The book demonstrates how simple machines are used in the construction of a fort.

The idea is engaging. Many kids want a practical reason for learning about simple machines. Making a fort is an attractive reason to learn about simple machines and to learn to use tools. However, the author chose a rather difficult format for this book, the nursery rhyme "The House that Jack Built." At the end of each introduction of a simple machine used to build the fort, we get a listing of all the simple machines used. It is repetitive and not that helpful.

What is lacking is a good definition of a simple machine. We are supposed to infer what a simple machine is through the list of items we are given that are simple machines. However, it doesn't quite work. At the end of the book, the author has a page that gives textbook definitions of simple machines, but the definitions aren't age appropriate for the target audience of the text. This information would have been much more useful embedded in the story of the grandpa building the fort. The author sprinkled little bits and pieces, but it needed to be more organized and direct to help kids walk away with a real understanding of why X is a simple machine and Y is not. Also why X is a specific type of simple machine. At the end the author has a little picture quiz with answers that tries to clarify some of the definitions, but that would have been better suited as part of the story.

Smash! Wile E. Coyote Experiments with Simple Machines

Smash!: Wile E. Coyote Experiments with Simple Machines (Wile E. Coyote, Physical Science Genius) is a great introduction to simple machines for kids. While cartoon stories sometimes depend too much on the cartoons and not enough on the science, this book doesn't disappoint.

For those familiar with the Road Runner and Coyote episodes this book will have a predictable feel. Each chapter explores a different simple machine having Wile Coyote attempt to use that machine to attack the Road Runner. In keeping with the cartoon theme Road Runner escapes unharmed in each instance, but a valuable lesson is learned about simple machines.

Wile Coyote's story is a good fit for simple machines as he's always using different methods to attack his nemesis. The author does a good job in staying with the Coyote traditional story line and embedding the science vocabulary and concepts around the story without losing the continuity of the story.

This is actually one of the best simple machine children's books I've read to date. The language is accurate and detailed. Children who come to this story knowing little about simple machines will learn the names of the simple machines and discover more about how each is used while being entertained. For children who have been introduced to simple machines, this provides more information and a great funny review of the material.
