Science Project on “A Water Turbine”, Project Experiment Topics on Energy in Different Forms for Class 8, 9, 10 and 12 Students.
A Water Turbine
Materials Required:
- A Cork
- A Knitting Needle
- Four thin pieces of plastic
- Proximity to a tap
Bore a hole through the center of a cork and insert a knitting needle through it. Make six slits on the surface of the cork and wedge thin slices of plastic into each slit. Hold the turbine under a steam of water.
The turbine rotates as the water hits the vanes. The speed will depend upon how fast the water flows. This is how water falls from the top of the dams on large water turbines which rotate and generate electricity.
The knitting needle passing through the cork serves as a central shaft that allows the cork to rotate. As the water falls on the thin strip of plastic, it pushes it down.
This makes the cork rotate and the next strip comes under the flowing water, this is again pushed downward and the cork continues to rotate.
The working of these basic machines has been developed with technology. Turbines in hydroelectric power stations work as water wheels but produce electricity if connected to a generator.
Even the modern adaptation of windmills is for the same purpose.
Even the forceful movement of sea waves can be utilized by wave generators to produce electricity. The energy of the sun has been tapped by solar cells which create electricity.
This electricity can in turn be used for a variety of purposes.
