(1) Build a house with cardboard with slanted roof and paint it with desired colour. Fix
the house to a thick base cardboard.
(2) Fix the solar panels on the roof . Fix the LEDs inside the house near a window.
Connect the output from solar panel to the LEDs. Connect to a swtich and fix the
switch behind the house.
(3) To erect a windmill, make windmill blades using an empty powder can. Fix the
blades to a circular disc and connect to the swindle of DC motor attached to a
vertical stand. Paint with desired colour and connect to a 9V battery through a
switch and erect the toy windmill on the base cardboard using plaster of paris.
