How can a little tugboat move a ship that's hundreds of times bigger than it is? In this episode of Carpool Classroom, Mrs. Nelson explores the surprisingly powerful world of tugboats! Young learners…
First, let's talk about tugboats.
Tugboats are basically the strong little helpers of the water.
They're much smaller than the enormous cargo ships, container ships, and other vessels they help.
But tugboats are specially designed to be powerful.
They have strong engines and propellers that can push a lot of water.
And tugboats have jobs that bigger ships sometimes can't do very well.
That ship might be hundreds of feet long.
It can't exactly make a quick three-point turn.
So tugboats can come alongside it and push or attach a strong towing line and pull.
They help huge ships turn, slow down, move away from docks, and get into the correct position.
But that still leaves our big question.
How can something so small move something so enormous? Here's our first clue.
The huge ship is floating.
