Twist, Dig, and Drill: A Book About Screws (Amazing Science: Simple Machines) Library Binding – January 1, 2006

Very concise and elementary explanation of a screw and how it works as a simple machine. Great everyday examples.

Love this book! It's a great science book about screws and yet very appropriate for a four year old. We coupled it with a tool set for him. He loved having it read to him.

I love this book and the others in the set! I teach 2nd Grade Science and used this set while teaching simple machines. The books are easy to understand, list many examples of the simple machine being discussed, and are colorful and inviting. The fact that it lists every day items that children are familiar with really helps them to better understand the simple machine it is describing. The end of each book includes an activity to explain how the simple machine is used, fun facts about that simple machine, and a glossary. Each book also includes a list of related books and web sites to continue the study and increase the curiosity of the simple machine being discussed. I highly recommend them all!

Shipped quickly and product was just as expected.
