First take a bottle of water and put a small motor inside it. then take a tube and paste it on the top of the bottle after that make a slide from the tube that help it to come down easily. Now yourDAM is ready
To make a working model of dam, take a water bottle and place a small aquarium motor inside it. Glue a tube on top of the bottle and make a slide from the tube which will help water flow easily.
Prepare an area for the experiment--over a sink, in a tub, or on a water table. Gather all your materials nearby.
Cut the top off the milk carton and lay the carton on its side. Measuring up from the bottom, go 1/2 inch up and poke a hole with the nail in the center of the side (hold the carton from the inside to keep it from collapsing). Moving up from that hole go up another 1/2 inch (1 inch total) and poke another hole above the first. Move up another inch (2 inches total) and poke a third hole in a straight line above the first two. Move up 2 more inches (4 inches total) and poke a final hole aligned with the rest.
Cover the four holes with a single strip of masking tape.
Mark the inside of the carton with a water line near the top to use when doing the experiment more than once and always fill to that line.
Fill the carton with water to the line and set the carton on so that the water will run into the drain.
Remove the tape quickly to allow water to drain from all four holes at the same time. Make note of how far each stream travels in the sink. Also, note what happens as the water runs out and the water level drops.
Re-tape the carton and do the experiment again. This time, though, only uncover one hole at a time, measure the distance the water travels and re-tape it. Move onto the next hole and do the same, refilling the carton to the fill line each time.
Provide answers to why the water from the hole closest to the bottom travelled farthest. That hole has the greatest mass of water on top, which equals water pressure, causing it to travel further and faster. This is how hydroelectric plants work in conjunction with dams. The water pressure at the base of the dam turns huge turbines that generate electricity.
There are many ways to make a working model of a dam. One is to use a water bottle and water.

Itaipu dam is a hydroelectric generating facility for Paraguay and Brazil. The model of the dam is clearly sketched on the map.
like dogs
dam dont know
i m zaid . i prefer the model which is more inventive dont make windmills, dam ok .i prefer you make model like trafic control such that it can solve the problem of city which is densed or some thing inven tive.ok
