Steam Turbine DART
Instructions:
Read the following sentences. Cut them up into strips and then order them so
that the passage makes sense.
For power plants built near the ocean, cold sea water is
often used in the condenser to absorb heat and carry it
away.
The steam that drives the turbines is part of a cycle.
Many power plants generate electrical current using steam
turbines.
The sea water is kept separate from the water that boils
and turns the turbines.
First, steam is produced by burning fuel to boil liquid water.
Then the steam is cooled back into liquid water in a
“condenser,” and that liquid water is reboiled to repeat the
cycle.
This steam spins the turbines as it passes through them.
Once you think you have the correct order, try to draw a diagram of what the
text describes.

Students will probably not be able to draw a detailed diagram of steam
turbine, but here is an illustration for reference:
