A clock for the sea — Watchmakers · The Makers
Joss reads about sailors who got lost because they did not know how far east or west they were. Help him understand how a very good clock solved it.
Your task
Pick the best answer at each step.
- The Earth turns 360° in 24 hours, so 15° each hour, or 1° every 4 minutes. Sailors compared the time of local noon with a clock still showing home time. The difference tells how far east or west they were: that is longitude.
- Invented guild stories to learn from. Never try fire, hot metal, glass, blades or power tools on your own: crafts like these are learned with a trained adult.
- Every craft came from many people in many places. Nothing about you is collected.
Score
- Craft knowledge — You understood how this craft works.
- Making it well — You put the steps in a sensible order and used the right tools.
- Care for people & planet — You kept people safe and used materials wisely.
In real life
In the 1700s the English clockmaker John Harrison built marine chronometers precise enough to find longitude at sea.
Watchmakers
The guild stories are invented, to learn from. Fire, heat, blades and tools are only for trained adults: learn these crafts with a trained adult, never at home. Nothing about you is collected; progress stays on this device.
