Reviews

VOYA Magazine
“With a friendly, relaxed writing style, Formichelli and Martin cover the history of timekeeping beginning with the first humans, who measured time simply by watching the seasons, and ending with the invention of astoundingly precise atomic and optical clocks. The book covers the development of the first calendars, interesting clocks throughout the ages, the world's time zones, and daylight savings time. Intriguing science experiments demonstrate various concepts of time and give the reader instructions to build several timekeeping mechanisms. The authors also include a timeline of major developments in the science of timekeeping and provide lists of websites and famous monuments involving time. To be able to address a topic as complex as that of time in such a concise and interesting manner is truly impressive.”

Booklist
“Versatile and hands-on projects range from very simple exercises that can be completed in moments, such as reading seasons from a shadow, to more sophisticated temporal experiments like making your own incense clock. These projects could be used as a fun diversion on a rainy afternoon at home or as the crux of an elementary science lesson.”

Children's Literature Review
“Do you ever find yourself running out of time? Who was it that set the standard for time anyway?. . . This timekeeping guide takes readers back to the beginning. Fun facts and timekeeping historical timelines can be found here. Readers will also find lots of activities for making their own candle clock, incense clock, hand sundial, and even finding time in the stars. There is a lot of fun information here. Teachers and parents will love making this guide a part of their library.”

Dig Magazine
“Timekeeping Explore the History and Science of Telling Time with 15 Projects takes the reader on a fascinating time-focused journey from past to present. Here’s the “how-to” on making your own hand sundial, finding a needle in a haystack, and testing pendulum power. One you’re sure to enjoy."

Dave White, Publisher, Social Studies for Kids
“Timekeeping: Explore the History and Science of Telling Time is well worth a read—or two or three. The fun illustrations complement the informative text, taking readers on a tour de force of time and timekeeping through the ages. With its combination of solid concepts and fun activities, this book will be a popular addition to the bookshelves of many a student, parent, or teacher.”

Marla Conn, Educational Consultant
"Timekeeping does a fantastic job of teaching the history of time from prehistoric days using simple sundials to present day GPS technology. The content meets the Common Core State Standards in math, science, social studies, and technology, while the activities provide interactive hands-on learning experiences that make learning fun and meaningful!"
