How to generate electricity from a small motor that is used in toy cars?

I want to build a small dam for a science fair but I am not getting the turbine for generating electricity. But I am having a small motor that is used in electric toy cars. Just tell me how to generate electricity from it by connecting it to a home-made turbine?|||Hydroelectricity makes use of conversion of water's potential energy into mechanical energy to turn generators to generate electricity.



A dam stores up the potential energy of the water and the flow from the dam provides kinetic energy for turning the generator.



You need to attach paddles to the motor shaft. Cause the water to flow against the paddles, like a water wheel. Electricity will be generated by the motor.|||Connect the rotating part of the motor to a parallel coil of wire and put the coil between the poles of a horse shoe shaped magnet and allow the motor to spin. an emf (current) should be induced on the coil provided the coil forms part of a complete circuit.
