A Ship in the Welland Canal
St. Catharines
This large ship waits inside a lock. As the water level changes, the ship rises or falls with it. Then the gates can open.
Did you know?
The Welland Canal bypasses Niagara Falls using eight locks.
Look together
What happens to the ship when the water level rises?
An idea to try
Draw the same boat at two different water levels inside a rectangle.
For the adult reading along
A little more to discover
The Welland Canal lets ships bypass Niagara Falls. Its locks overcome the difference in level between the two lakes. The drawing simplifies a lock and a cargo ship; it does not show every installation or a particular manoeuvre. Gravity moves water into and out of the locks.
