We just learned about the Turbine.
Another part of machine science is a Steam Turbine.
Remember a turbine is like a water wheel where it has blades that are pushed along.
When liquid is heated up and creates steam, the movement of the steam goes over the blades and makes them move.
These moving blades spin around a rod in the middle that helps create electricity or move a part of a machine.
