Teaching Overview
Learning Points
- Each spring, thousands of fish migrate to their breeding grounds to spawn and lay eggs.
- In Utrecht in the Netherlands, many fish migrate through the city’s canals, but sometimes find their route blocked by locks, which makes them vulnerable to predators.
- The fish doorbell is a livestream that anyone can watch, to see if fish are waiting; if lots of fish are trapped, the lock keeper can open the gate and let them through.
Curriculum Keywords
