Your task
Is each sentence true or false?
- Tides are the slow rise and fall of the sea. They are mostly caused by the pull of the Moon, with a smaller help from the Sun. On many coasts there are two high tides a day, and each one comes about 50 minutes later than the day before.
- 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
Today giant container ships still time their arrival to the tide in some ports, and tide tables are published for almost every coast. The same pull that moves tides can also be used: tidal power stations turn the moving water into electricity.
Shipbuilders
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.
