Canal Activity

Can you navigate a canal barge through a lock?

Think about the operations that are necessary to pass from the highest part of the lock to the lowest.
Which sluices (paddles) have to opened and closed and when to prevent the water draining out, maintaining level or causing a flood?

Flash version - find the correct order to move the barge through the lock by clicking on the actions in the order they must operate. Start activity.
