Hydroelectric power station

The video explains why salmon need ladders, focusing on the impact of hydroelectric power stations. It describes how these stations generate electricity using water and how dams can block salmon from swimming upstream to spawn. To help salmon overcome this obstacle, fish ladders are built, such as the one in Pitlochry, Scotland.

Why do salmon need a ladder according to the video?

• To build nests

• To find food

• To climb trees

• To overcome obstacles in their path

What is the primary function of a hydroelectric power station?

• To store water

• To generate electricity using water

• To provide habitat for fish

• To control floods

Which component of the power station converts kinetic energy into electrical energy?

• Generator

• Turbine

• Dam

• Reservoir

What challenge do dams present to salmon?

• They attract predators

• They reduce oxygen levels

• They increase water temperature

• They block salmon from swimming upstream

What solution is implemented at Pitlochry in Scotland to help salmon?

• Constructing a tunnel

• Creating a fish ladder

• Installing a water pump
