Wells of Knowledge Science Series
"terrific teaching tool"
(School Library Journal)
provides an age- appropriate depiction of the history of
measuring time--from simply observing the movement of the sun to using
shadow stick clocks to our modern atomic and quartz clocks.
book also covers
time zones, meridians, and more. It actually verges on covering too much information for one audience, but it's still a really interesting, good read that will leave kids feeling like questions have been answered!
