Tools of Timekeeping:
A Kid's Guide to the History & Science of Telling Time

"Hitch a ride with Tools of Timekeeping if you want to travel through history and find out why we keep time the way we do. It’s a fascinating glimpse into humanity’s efforts to tame time."
—Jude Isabella, Editor of YES, Canada’s Science Magazine for Kids

"Tools of Timekeeping is a wonderful resource. Knowing how people first learned to think about time and its division gives great context to the devices and tools—like calendars and clocks— that we take for granted."
—Terry Devitt, Editor of The Why Files, “The Science Behind The News”

"An excellent book to help families explore the past and future of time and timekeeping."
—Richard Paselk, Ph.D., Curator, Scientific Instrument Museum at Humboldt State University
