Sailors knew how to measure latitude, their location north or south of the equator, but they could not measure longitude, their location east or west of their home port. Because of this, many lives were lost worldwide. The key to solving this problem lay in devis

I felt this missed the mark. While Borden covers all the major points, I don't feel she got across to the young reader just how this clock maker solved the longitude problem. The emphasis was on the battle the Harrisons had to fight before finally being awarded the prize for solving the longitude puzzle. While interesting, a great human interest story and a cautionary tale...fighting "city hall" is not for the faint is not truly the important part of the story. The important part is ...more

For many years sailors knew how to measure latitude for their location of north or south of the equator. But they could not measure longitude of their location east or west of their home. This caused many people to die because getting to a certain location was hard. To solve this problem a certain clock was made so that this wouldn't happen anymore. John Harrison worked for more than forty years to create the perfect clock.

This picture book is great for introducing longitude and latitude to an e

This book was interesting. It was set up more like a fiction, story like read rather than a fact read, which is cool for an informational book. But it goes on the adventure of creating the first sea clock. This wasn't something I found super interesting. But the way the book is written is very cool!

I found this book a bit boring and long for a children's book though I believe this would work well in a history or social studies classroom and depending on the student they might find this interesting. I would not use this for any grade.

I thought that this book was a great informational book in relation to social studies; the more geographical and historical aspect of it. I also thought that it would be very appealing to young readers because of the illustrations and depiction of the world on the cover of it. Growing up, the bigger the concepts, the more interested I would become. This book tells the process of creating a longitude clock for sailors in the 17th century. It tells the good, the bad, and the outcome of each making ...more

Sea Clocks is "the story about longitude"; the story about how to solve the problem of understanding where a ship's location was when placed at sea. It follows the historical life of John Harrison, the clockmaker who tried to solve the problem of this longitudinal enigma. Although the story gives an accurate and historical account of the thought processes and clock-making trials of Harrison, it quickly becomes tedious and repetitive as clock after clock is described how and why it was created an ...more

Fittingly enough, Sea Clocks’ plot line follows the chronological timeline as sea clocks were invented and subsequently implemented. This story breaks up its sentences so that they are short yet still reminiscent of natural speech rhythms, which may help reluctant and slow readers. It is a bit heavy on what seems to be unimportant details at the beginning, though the text picks up pace and shares the story of how John Harrison created the sea clock (to solve the “longtitude problem”). It does no ...more

A great informational text read-aloud on the amazing perseverance, stick-to-it-iveness, and ingenuity of John Harrison, the humble and now-famous inventor of Sea Clocks. Great art accompanies this fascinating text! Very accessible for grades 5+.

Strongly recommended! :)

well worth reading.

It was a Yorkshire carpenter who made the first clocks accurate enough to determine Longitude at sea.

Determining Latitude is easy.

Determining Longitude is far from easy.

The story of how one clock maker found the answer to telling a ships longitude at sea. This helped everyone navigate the waters better.

Interesting story, but felt that it might lose a kid's interesting with the style of writing. It barely held my attention.

I was reminded of this book because I read an essay about the longitude prize and all the scientists who worked on it. I loved that I could find a children's book about this.

There were already two Louises in my family when I was born: my mother and my grandmother, Nana, who lived with us when I was growing up. So early on, I was given the name Leezie. This is a name that my family still calls me. Years later, my niece was born and also named Louise. Then there were four of us with the same name! Louise is a fine name to have except that people often spell it incorrect ...more
